These links use the current product catalog titles. They are starting points for discussion, not a compatibility guarantee. Confirm ratings, supported settings and available documents for the exact version before ordering.

How to choose a BMS for your battery pack

What to specify What to confirm with the supplier
Chemistry & series count Cell model, chemistry, number of cells in series, pack voltage range and required protection settings.
Charge & discharge current Continuous current, peak current and its duration, charger requirements and the conditions used for the rating.
Installation & temperature Board dimensions, mounting, enclosure space, heat dissipation and operating environment.
Protection & balancing Required voltage, current and temperature protections; balancing type, current and activation conditions.
Wiring & port arrangement Common or separate charge/discharge ports, connector pinout, harness and the model-specific wiring instructions.
Communication Electrical interface, protocol, message definitions, firmware version and compatibility with the host equipment.
Production supply Sample and batch quantities, approved revision, inspection requirements, forecast and component-change notification.

Request the documents for your selected model

No PDF downloads are currently published in this resource guide. Document availability and release conditions must be confirmed for the selected model. Tell us which of the following you need:

  • Datasheet with ratings, protection thresholds and test conditions.
  • Dimensional drawing and connector or harness information.
  • Model-specific wiring and installation instructions.
  • Communication protocol and supported firmware information.
  • Configuration software or app instructions, where applicable.
  • Available test reports and their model / version coverage.

Include the product link or model, intended chemistry, series count and required document revision. Use the document-request button beside a model below to start a WhatsApp conversation with that product included.

Questions before placing an order

Does RS485, CAN or Bluetooth mean the BMS will work with my equipment?

The interface name alone does not establish compatibility. Request the protocol, connector pinout, firmware version and any host-side requirements for the exact model.

Can I use one model for both NMC and LiFePO4?

Ask whether the exact hardware and firmware support your chemistry and series count, and request the applicable protection settings. Do not infer support from a broad category name.

How should I compare current ratings?

Provide your continuous load, peak load and peak duration. Ask for the conditions behind the published rating, including temperature and installation requirements, before comparing options.

Can I get wiring instructions from another model?

Request instructions for the exact model and revision you receive. Confirm the harness and connector pinout with the supplier before integration.

What should I send if I need custom BMS development?

Send the electrical and mechanical requirements, communication needs, sample quantity, annual demand and target schedule. Ask which changes are configuration options and which require new engineering work.
