Why choose this SOK battery
More run time, cold-weather support and local monitoring in one pack.
Built-in heaterThe heater helps protect cold-weather charging down to the conditions stated by SOK when the battery is installed and operated correctly.
Bluetooth monitoringUse SOK's documented ABC-BMS app workflow to view battery information from a compatible iOS or Android device.
200A continuous outputThe BMS supports substantial 12V loads, provided cable size, terminals, fusing, disconnects and inverter surge demand are correctly designed.
System fit
Set every charger for the battery's 14.6V LiFePO4 profile.
SOK recommends 56A charge current, lists a 120A maximum charge current and specifies 14.6V charging. Confirm solar controller, shore charger, alternator charger and inverter/charger settings before connection.
12V systemsUse with 12V equipment or a properly sized inverter; do not connect 24V or 48V loads directly to one battery.
Series and parallelSOK permits parallel expansion and lists no more than four batteries in series, with a voltage balancer. Follow the manual and equalize state of charge before connecting.
High-current loadsCalculate continuous and surge current at the battery, then size conductors, protection and disconnects with installation margin.

Common questions
SOK SK12V280H 12V 280Ah Heated Bluetooth LiFePO4 Battery FAQ
Does the battery heat itself?
It has a built-in heater pad intended to support charging in cold conditions. Operation depends on battery state, temperature and the control logic described by SOK; it is not a substitute for proper installation.
Which app should I use?
SOK directs customers to the ABC-BMS app for Bluetooth monitoring. Follow the current SOK manual and app instructions for setup.
Can I connect multiple batteries?
Yes, SOK supports parallel expansion and limits series connections to no more than four batteries with a voltage balancer. Use matched batteries at equal state of charge.
Will it run a large inverter?
It may support substantial inverter loads, but inverter size must be based on the 200A continuous limit, surge behavior, cable voltage drop and all other system loads—not watts alone.
