Yes, a 6S LiPo BMS is required for the parallel connection of identical 6S LiPo batteries.
- A BMS is the primary way to prevent a battery pack from catching fire, so if you’re on the fence, you definitely need a 6S LiPo battery BMS. You also need an equalizer, sometimes they’re built into the BMS, and sometimes they’re not.
- A BMS board monitors each cell and if the voltage of any one cell in the pack deviates too far from a safe range, it disconnects the pack from the load. This can prevent overcharging and over-discharging, both of which are required for different reasons.
