When the ambient temperature is below 32°F (0°C), the charging current will only supply power to the heating film inside the battery. When the internal temperature of the battery reaches 50°F (10 °C), BMS will immediately turn off the heating function, all the charging current charges the battery.NOTE: The battery needs to be charged to turn on the heating function and the charging current is at least 5A. Bluetooth lifepo4 battery has higher energy density, more stable performance and greater power. It can be repeatedly charged and discharged without any memory effect. The battery can be charged and used no matter what state it is in. Our chins lifepo4 battery can be connected in parallels and in series for larger capacity and voltage.
Allow to be extended up to 4 in series and 4 in parallel (Max 4S4P) to get more capacity (Max 400Ah) and higher voltage (24V, 36V, 48V). Our lithium iron phosphate battery can be used in various areas, perfect for Caravan, Solar, Marine, Home Storage and Off-Grid etc. If the load you are using contains trolling motor, the maximum continuous output current of our battery must be twice of the motor.
Otherwise, our batteries cannot run your device. You can also consult us about this issue before purchasing the product, our engineers will give you the advice. In addition, our batteries cannot be used as a car starter battery. Nominal Voltage: 12.8V Charge Voltage: 14.2V - 14.6V.
