BMS protection and charging

The onboard BMS disconnects the battery internally if voltage falls below 10V or rises above 15V. These are protection thresholds, not charging targets. If protection activates, follow Vault Power's recovery procedure. Use charging equipment and settings approved for this LiFePO4 battery; the separate Vault sodium-ion chargers are not established as compatible with this model.
