FAQs

What is this 12V 300Ah battery mainly used for?

This battery is designed for larger 12V deep cycle power systems that need high capacity, strong output, and longer runtime.

Does this battery support Bluetooth monitoring?

Yes. This model includes Bluetooth APP support, allowing users to view battery information, monitor system status, and manage battery functions from a compatible mobile device.

Does it have a built-in heating function?

Yes. The battery includes internal heating. During charging, the heater activates automatically below 41°F (5°C) and stops once the cell temperature reaches 59°F (15°C). Low-temperature charge protection is also built in.

Can multiple batteries be connected together?

Yes. The manual states that up to 4 batteries can be connected in parallel for higher capacity, and up to 4 batteries can be connected in series for systems up to 48V.

What are the charging parameters for this battery?

The manual lists a max charge voltage of 14.6V, a max charge current of 250A, and a recommended charge current of 100A. For bulk/absorption charging, the recommended range is 14.2V to 14.6V.

What protections does the built-in BMS provide?

The built-in BMS helps protect against high voltage, low voltage, high temperature, low-temperature charging, and high current conditions. It also supports passive balancing near the top of the charge cycle.
