Ampere Time 12V 300Ah, 3840Wh LiFePO4 Battery & Built in 200A BMS

Our battery can be used well below 0C (can be normally discharged), but we don’t suggest charging the battery below 0C.
It is like most kinds of the battery in the market now:
Operating Temperature: Charge: 0°C--50°C; Discharge: -20°C--60°C.
Currently our battery can be charged at low temperature, but it is charged with a very small charging current. And we’ve used auto motive grade battery cells which have superior quality. Even if charging in low temperature environment for emergency usage, it will not damage the battery.
We're planning to sell batteries with self-heating functions which allows it to be charged in freezing temps in a few months, and you could keep an eye on our store if you're interested.

Our 12V 300Ah battery with built-in 200A BMS has 3840Wh energy and could support max. 2560W load power and max. 200A continuous charge/discharge current.
If you use 546W for 6hrs, it will cost 546W*6hrs=3276Wh each time, and our 12V 300Ah battery with 3840Wh energy could support it.

Our 12V 300Ah battery could support max. connection as 4 in series for 48V, and 4 in parallel for 1200Ah. And you could connect them as 2 in series and 4 in parallel.
Please feel free to contact us for more connection suggestions.

Since lithium battery from different brands has their special BMS, we do not suggest you to combine batteries from different brands together as a system.
We recommend connect batteries with the same capacity from the same brand.

Our 12V 300Ah battery supports max. 2560W load power, and max. 200A continuous charge/discharge current. Pls kindly help check whether the battery could support your application.

The case of our 12V 200Ah and 300Ah battery is the same, and they have different amount of cells inside.

Our 12V 300Ah battery with built-in 200A BMS has 3840Wh energy, and supports max. 2560W load power and max. 200A continuous charge/discharge current.

Each 12V 300Ah battery build-in 200A BMS has max. 2560W load power.
If you use solar panels to charge your battery it is affected by the sun shine.
As you’re using a 400W solar panel to charge our battery, it will take more than 3840Wh/400W=9.6hrs to fully charge our battery with effective sunshine. Assuming that you could get 5hrs effective sunshine every day.

Our batteries do not currently have a communication port functionality, we are working on a plan, it is expected to go online this year.

We recommend the battery under voltage warning voltage at 11.6V and under voltage warning reconnect voltage at 12V, if you need more parameter of setting ,pls kindly contact us, and we will try our best to support you.

As our battery is not a starter battery, we don’t suggest you use it to start your car in long-term uasge, but it's okay to use it to do so for emergency.

You could mount it without a cover and strap it down, but need to make sure that the post bolts will not expose to water when it's charging/discharging. Or if you're not sure, pls feel free to contact us for more suggestions.
