Description:
(1) Output with high efficiency: Standard discharge current is 0.5C-0.8C , instant impulse discharge current is 10C for 10 seconds.
(2) Good performance under high temperature, it could work under 60°C temperature. The battery structure is safe and good.
(3) Good performance under low temperature. discharge capacity decreases to over 78% under 0°Cand discharge capacity decreases to over 70% under-20°C.
(4) Good safety performance: When the pressure inside the battery is too large, the one-way safety valve will release gas and heat to make sure battery perform well. When the internal pressure reaches a certain level, the valve will be open immediately which can protect the battery from burning and explosion.
(5) Good cycle life time, the discharge capacity is still over 80% after 2000 cycle times of single cell (80%DOD).
(6) It can fast charging. It could be charged to 80% within 20 minutes and charged full with 2-3h.
