A BMS (battery management system) protects a lithium forklift pack by balancing cells, limiting over-charge/discharge and reporting state of charge. ForkliftIQ supplies BMS units compatible with Heli, Hangcha, EP, Toyota, Linde, Jungheinrich, Hyster, Crown and other major brands lithium packs.
What the BMS does
The BMS monitors each cell, manages charge/discharge limits, controls cooling and communicates state of charge to the truck. A faulty BMS can shut the pack down or mis-report charge — match it to the pack chemistry and voltage.
Parts grade — OEM, aftermarket & economy
| Grade | What it is | Best for |
|---|---|---|
| OEM / Genuine | Original manufacturer part number | Warranty & critical components |
