Description:
(1) Output with high efficiency: Standard discharge current is 0.3C-0.8C,
(2) Good performance under high temperature, it could work under 65°C temperature. The battery structure is safe and good.
(3) Good performance under low temperature. discharge capacity decreases to over 78% under 0°C and 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.
Applications:
Electric motorcycle ,electric scooters ,electric golf car ,electric tricycle
Remote control cars, boats, aircraft and other toys
Solar and wind power energy storage equipment
UPS and emergency lights, warning lights, miner's lamp (best safety)
