Custom engineering and B2B supply for agricultural and industrial drone platforms, supported by Herewin battery manufacturing and Xingtu Brazil market execution. The program begins with the real aircraft, battery bay, connector, communication, payload, working cycle and field-charging routine—not with a generic claim that one pack fits every drone.
One engineering path, with responsibilities clearly divided.
Xingtu Brazil and Herewin Power work as a joint commercial and engineering program for Brazilian buyers. Xingtu Brazil owns the local buyer conversation and commercial path. Herewin owns the battery-engineering and manufacturing work. This division keeps technical questions close to the factory while giving Brazilian buyers a Portuguese-language commercial route, import planning and local coordination.

Why custom development matters
A battery is part of the drone power system, not an isolated box.
Two aircraft may perform similar agricultural work and still require different packs. The battery must fit the platform electrically, mechanically and operationally. A label match alone does not confirm that the connector, communication, discharge behavior, housing or charging workflow is appropriate.
Power system
Voltage architecture, motor and controller demand, discharge profile and protection strategy must be reviewed together. An apparently similar pack may behave differently under takeoff, lifting or spraying loads.
Payload and mission
Spraying, spreading, mapping, inspection and lifting create different weight, power and endurance priorities. The project starts with the actual mission rather than a universal capacity recommendation.
Battery bay and dimensions
Available length, width, height, retention points, handle clearance and insertion direction determine whether a pack can be used safely and serviced efficiently.
Connector and interface
Power connector, signal connector, cable direction, mechanical interface and locking method need photos or drawings. A visual resemblance is not enough for compatibility.
Communication
The aircraft, battery and charger may exchange state or protection information. Protocol, message behavior and connector pinout require project-specific confirmation.
Flight and work cycle
Takeoff frequency, payload changes, reserve practice, battery rotation, cooldown and operator behavior determine the practical energy and charging plan.
Agricultural field routine
Dust, moisture, transport, repeated handling, chemical exposure and long field days affect housing, labeling, connectors, charging discipline and spare-pack planning.
Charging environment
Grid power, generator use, vehicle-based power, available phases, ventilation and field layout influence charger selection and the safe rotation of packs.
The review may lead to a customized pack, an adapted platform, or a request for more evidence. Fit is confirmed only after engineering review and written approval.
Application priorities
Agricultural drones first, with engineering paths for other industrial UAVs.
Agricultural spraying, seeding and spreading remain the program's primary focus because their operating routines place unusually high demands on battery rotation, charging and continuity. The same engineering method can be applied to other professional UAVs when the platform and mission are clearly defined.
Application names describe engineering directions. They are not claims that one public product is already validated for every aircraft in that category.
Agricultural spraying
Review the aircraft, tank or payload profile, repeated sortie pattern, field temperature, battery rotation, connector handling and charging resources.
Seeding and spreading
Evaluate load changes, frequent takeoff, work-cycle length, field logistics and the number of packs needed to keep the operating team moving.
Route, takeoff frequency, payload, reserve policy, charging base and repeatable turnaround determine the appropriate battery and charger direction.
Surveying and mapping
Mission duration, equipment load, operating altitude, field temperature and reserve strategy guide the energy-density and pack-integration review.
Inspection
Power demand, sensor package, access environment, mission repeatability and downtime tolerance shape the technical proposal.
Firefighting
Emergency use requires a clearly documented mission, load, thermal environment, operating protocol and validation plan before any configuration is proposed.
VTOL platforms
Transition loads, cruise profile, battery compartment, communication and aircraft-level validation must be handled as a complete integration project.
Long-endurance applications
Energy density, pack weight, discharge needs, cooling, reserve policy and aircraft balance are reviewed together without promising a fixed endurance result.
Customization matrix
The dimensions that move from buyer evidence to an engineered proposal.
The matrix is a project brief, not a public specification sheet. Exact values are requested from the buyer, checked against the aircraft and then confirmed in a model-specific proposal.

Battery technology directions
Capability directions selected by the mission—not a list of fixed best sellers.
Herewin's engineering scope allows the team to compare pack architectures and charger concepts. The correct direction depends on aircraft demand, weight, available space, environment, validation method and commercial order plan.
High-rate batteries
For missions where peak and sustained power demand must be evaluated against temperature, pack structure and aircraft behavior.
Smart UAV batteries
For projects that need battery-state information, protection behavior or communication matched to the aircraft and charger.
High-voltage packs
For platforms designed around higher-voltage architectures, subject to aircraft, connector, insulation and charger review.
High-energy-density packs
For weight-sensitive or endurance-focused missions where energy, structure, discharge and validation must be balanced.
Semi-solid options
An engineering direction that may be evaluated when platform, mission, availability and project evidence support it.
Heavy-lift solutions
Pack, multi-pack, current, retention, cooling and fault-management concepts for clearly defined heavy-lift platforms.
Long-endurance solutions
Energy and weight optimization for a defined aircraft and reserve policy, without a universal flight-time promise.
Customized PACK development
Electrical, mechanical, BMS, connector, housing, label and packaging work organized around the buyer's platform.
UAV chargers
Single- or multi-channel concepts matched to the confirmed battery, field power and operating rotation.
Performance values, chemistry, architecture and availability are confirmed only in the selected model's technical proposal.
Smart BMS and communication
Protection and information must match the real aircraft and workflow.
A smart BMS can support monitoring and protection decisions, but its usefulness depends on the cells, pack, sensors, aircraft, charger and communication requirement. The project therefore begins with the current system: what the operator sees, what the aircraft expects, which faults occur and how the battery is charged and rotated.
Voltage, current and temperature monitoring can be considered alongside protection logic and state information. The proposal defines what is measured or communicated for that project. Public capability language is not a promise that a particular battery will exchange data correctly with an unreviewed aircraft.
Protocol names indicate review capability only. Compatibility is not confirmed until the interface and platform behavior have been validated.
Voltage monitoring
Review pack and cell-level monitoring needs against the selected architecture and protection plan.
Current monitoring
Relate operating current, peaks and fault behavior to the real mission and aircraft demand.
Temperature monitoring
Consider sensor placement, charging, discharge, cooldown and the field environment.
Protection logic
Define relevant limits and responses as part of the engineered battery and aircraft validation plan.
State information
Confirm which state or alarm information is needed by the operator, charger or aircraft.
Communication matching
CAN, UART or project-specific communication remains subject to pinout, message and platform engineering review.

Chargers and field charging
Battery count and charger choice are an operating-system decision.
A field team does not operate a battery in isolation. It rotates packs through flight, return, inspection, cooldown, charging and readiness. Aircraft count, operators, sortie length, payload changes and acceptable downtime all influence how many packs and chargers the team may need.
The power source also matters. Workshop power, a rural grid, generator, vehicle supply or field base creates different input, ventilation, cable and handling constraints.
No charging time is published here. Charging performance and safe workflow depend on the confirmed battery, charger, input power and operating conditions.
Single-channel concept
May suit evaluation or lower-throughput routines when the electrical input and operating rhythm are confirmed.
Multi-channel concept
May support a larger rotation, but channel count alone does not determine real turnaround.
Charging rotation
Map flight, return, inspection, cooldown and charging so packs are not treated as permanently ready.
Field power conditions
Record voltage, phase, generator or grid conditions, grounding, ventilation and cable layout.
Charger matching
Confirm battery architecture, connector, communication, input power and intended operating routine.
Cooling and handling
Define a protected area and operator routine for hot, damaged, wet or suspect packs.
Battery count per team
Estimate from aircraft count, mission cycle, charger resources and reserve policy after collecting evidence.

Buyer requirement checklist
Better evidence creates a faster and safer engineering review.
The first enquiry does not need a finished engineering document. It should, however, identify the real aircraft and provide enough visual and operating evidence to prevent assumptions. Use the downloadable checklist to collect information from operations, maintenance and purchasing before the technical call.

Customs-related product information
Commercial and technical details prepared for import coordination when applicable.
The page does not guarantee that every listed certificate or document applies to every battery. Applicability is confirmed in writing before shipment.
OEM and private label
Brand presentation comes after product and compliance fit.
An OEM program can include more than placing a logo on an existing pack. The buyer should define the channel, brand responsibility, languages, product identity, manual needs, packaging route and expected continuity. Engineering and transport information must remain accurate even when the commercial presentation is customized.
Artwork begins after the battery direction is clear. Sample approval, color control, label content and responsibility for brand files remain part of the commercial review.

Connector options
Evaluated electrically and mechanically rather than treated as a cosmetic choice.
Housing options
Reviewed against fit, protection, cooling, handling and production feasibility.
Project configuration
Battery, BMS, communication, charger, label and packing organized as one controlled scope.
All OEM and private-label options remain subject to technical, documentation, authorization and commercial review.
Brazil commercial path
Local coordination before, during and after the manufacturing work.
Xingtu Brazil does not stop at forwarding a supplier quote. The local team helps the buyer prepare evidence, defines who will validate the sample, organizes the commercial proposal, plans import and delivery, and keeps the after-sales and repeat-order conversation connected to the original configuration.
Customized projects are normally produced in China for confirmed orders. Standard Brazil stock is not implied; future stock requires compatibility evidence, repeat demand and a justified commercial case.
01
Portuguese communication
Clarify the operating problem and keep technical questions understandable to the Brazilian buyer.
02
Requirement preparation
Convert photos, labels, dimensions and operating information into a structured engineering brief.
03
Commercial proposal
Present the confirmed scope, quantity, responsibilities and offline commercial conditions.
04
Shipment planning
Align battery configuration, packing, documents, route and handoff points before dispatch.
05

07
After-sales communication
Collect traceable evidence of problems and coordinate technical review with the manufacturing partner.
08
Repeat ordering
Reconnect the next order to the approved configuration, operating feedback and continuity plan.
An enquiry is not a purchase, quotation or stock reservation. Product, specification, quantity, price, route, availability and final terms require written confirmation.
