LFP26650-3400 Ultra-Cold Lithium Iron Phosphate Battery

Cold Weather Battery

Product Features

It is well known that normal lithium-ion batteries are not good at low-temperature environments, lithium precipitation will occur if inappropriate usage, which is very likely to have a decrease in both electric and safety performance.

In order to effectively improve this major deficiency, JYH has expended a great deal of research and development efforts, adjusted and optimized the formula of the battery cells. Through unremitting efforts, we have achieved remarkable results, enabling lithium iron phosphate batteries to excel in charging and discharging capabilities under sub-zero temperatures. These low-temperature batteries not only maintain functionality below zero degrees but also boast a discharge capacity approaching 90%.
