This Battery does not have a low temperature heating function. Please do not charge the battery in a temperature lower than 32°F (0℃) to avoid damage to the battery.
1, Charging Temperature : 32°F（0℃ ) to 122°F (50 ℃).
2, Discharge Temperature : -4°F ( -20 ℃ ) to 140°F ( 60 ℃ )
3, If it is a 4-string lithium iron Battery pack, the charge protection voltage is 3.65v=14.6v, and the discharge protection voltage is 2.5V*4 = 10V.
How to charge the Battery?
Scheme 1: You can use a lithium iron phosphate 4-string(14.6V) charger to charge the battery pack.
Scheme 2: You can use photo voltaic solar panels to charge the battery through MPPT.
Scheme 3: You can use the inverter to charge the battery pack (note: the inverter needs a built-in AC to DC charging function)
NOTE: It is recommended to set the 12.8V lifepo4 battery controller (MPPT) or inverter discharge cut-off voltage to 10.8V. In this way, MPPT can give priority to the protection of the battery and extend the service life of the lifepo4 battery.
(25.6V lifepo4 battery controller /MPPT or inverter discharge cut-off voltage to 21.6V)
