Not at 0 degrees: can work normally. After placing the fully charged lithium-ion battery pack for two months, its capacity is greater than or equal to 80%. Ordinary lead-acid batteries are placed for two months, only 40%-50% of the nominal capacity.Do not remember half the charge is not a problem, the battery charge-discharge cycle life, life expectancy of up to. The Battery equippes with BMS and PCB protective plate in battery. BMS is used to supervise battery by measure its voltage, temperature, current and SOC (State Of Charge), give out alarm under wrong circumstance, cut off electric power link in severe situation in order to protect battery and make its life longer. BMS can balance energy among batteries to make them more identical and expand its discharge cycle.
The lithium battery is non-toxic and non-odor that is safe to use. Compared with ordinary lead-acid batteries, which have a large amount of heavy metal lead which is harmful to the human body and the environment, lithium-ion batteries are highly environmentally friendly products. We will do our best to make you satisfied and enjoy this shopping. Charging current: up to 2A. Charge cut-off current: 0.03C.Charging time: ~7h (2A charger).
