  • Page 4 1.3-Checking and Bluetooth app ① When first receiving the battery, the voltage should be e ither 0V or around 13V. • The newest model BMS has a storage mode which completely shuts off of the BMS. In this state, the terminal voltage should be at 0V and the device will not show up in the Blue- tooth app device list.

Periodically check to ensure all batteries are the same voltage, especially when the bank is fully charged.
  • Page 10 3.1 - AC to DC charger A charger with a charge voltage of 14.4V to 14.6V is required for SOK 12V battery. A charger with a voltage of 28.8V to 29.2V is required for SOK 24V battery. Most AGM battery chargers produce charge voltages within that range and would be compatible with SOK lithium batter- ies .
