48V 51.2V 105Ah IP67 LiFePO4 Marine Boat Propulsion Batteries: Featuring Magnet Power Off Switch

Supports 20 batteries parallel connections *51.2v 105Ah.

Special features:

Linkage with the BMS

• Normal operation: When the magnet approaches the Hall switch, the BMS recognizes it as "on" and allows the battery to be charged and discharged.
• Triggering power cut - off:
  When the magnet is removed (e.g., removed manually or separated due to the device tilting), the Hall signal disappears, and the BMS cuts off the main circuit within seconds.
  Combined with the built - in protection of the BMS (over - charging, over - discharging, over - temperature), double safety protection is achieved.
