BUYER GUIDE
JK BMS Buying Guide for Lithium Battery Packs
A buyer guide for choosing JK BMS and similar smart BMS boards by series count, current, balancing, Bluetooth, display and communication.

Key Points for Buyers
- Confirm battery chemistry first because Li-ion and LiFePO4 use different voltage ranges and protection settings.
- Match series count, such as 4S, 8S, 16S or project-specific packs, before comparing current and price.
- Check charge current, discharge current, active balancing current, Bluetooth, display, CAN or RS485 requirements.
- For ESS projects, communication compatibility with inverter or monitoring equipment should be checked before ordering.
RFQ Information to Prepare
- Target model or product type
- Voltage, capacity and current requirement
- Application and installation space
- Quantity and destination country
- Packing, labels and document needs
