LILEAD D125 12V lithium deep cycle batteries perform better than lead acid batteries in most weather conditions. It can charge between temps of 0 and 55 32°F ~ 131°Fand can discharge between -20 and 60 -4°F ~ 140°F at 100% rate.

LILEAD D125 12V lithium deep cycle batteries need to be above freezing in order to charge them. As a result, it is best to use the batteries in a climate controlled location (not on the tongue of a trailer or using a lead acid battery compartment that has to be ventilated, thus allowing freezing air to circulate around the battery).

LILEAD D125 12V lithium deep cycle batteries can be placed in an insulated space, inside the yacht/ boat/ RV or other climate controlled areas. Some users have suggested using a battery heating pad that you can find online. We recommend using the battery in a climate controlled location.

Does the BMS limit charge current?
LILEAD 12V/24V lifepo4 battery BMS do not limit the charging current. Well, nearly all 12V/24V lifepo4 batteries standard charger, their charging model is CC (constant current) to CV (constant voltage). CC charge stage, the charge current is determined by charger, when battery volt reached 14.4V-14.6V, charge mould turn into CV charge. At CV charge stage, the charge volt is constant and charge ...more
