BMS & Balancers

A BMS (battery management system) protects a lithium pack from overcharge, over-discharge, short circuit and overheating, and keeps the cells balanced. We stock JK Smart BMS for 4S–8S and 24S packs, JK Inverter BMS for 8S–16S solar batteries, and smaller boards for 3S–5S lithium-ion packs.

Before you buy

  • Match the string count to your pack: 4S for a 12V LiFePO4 battery, 8S for 24V, 16S for 48V, 24S for 72V.
  • Pick the amp rating above your highest continuous load. A 3000W inverter on a 48V battery draws about 60A, so a 100A BMS leaves headroom.
  • For a battery that talks to a solar inverter over CAN or RS485, choose a JK Inverter BMS (PB series).
  • Active balancing (0.4A to 2A on JK) moves charge between cells and matters most on large 100Ah+ packs.
