Compatibility note: These links are related battery products, not confirmed compatible accessories for this 4S LiFePO4 BMS. Check battery chemistry, cell count, voltage, and connector requirements before linking them as a compatible bundle.
Use only a battery pack with the correct LiFePO4 chemistry and 4S configuration.
Confirm the BMS terminal markings and wiring diagram before connecting the battery.
Verify cell order and polarity before applying power.
Use a charger specifically suitable for the assembled 4S LiFePO4 pack.
Do not exceed the BMS's confirmed current rating.
Installation should be performed by someone familiar with lithium battery wiring and protection systems.
