The BMS includes low-temperature charging protection. The specified charging range is 0°C to 60°C, while discharging is permitted from -20°C to 60°C. If the battery is below 0°C, allow it to warm into the charging range before recharging.
Yes, through a LiFePO₄-compatible solar charge controller. Choose a controller that suits your panels and supports the battery’s charging voltage, current and temperature limits. Connect the panels through the controller rather than directly to the battery.
Please contact our support team with your planned system voltage, capacity and battery models before connecting multiple batteries. We will confirm whether your proposed configuration is supported and the maximum permitted number of batteries.
Only if it supports this battery’s LiFePO₄ charging requirements. Use CC/CV charging at 14.4V ± 0.2V, with a recommended current of 4A and a maximum of 20A. Lead-acid equalisation and repair modes should remain disabled.
