Basic Performance
(1) Output with high efficiency: Standard discharge current is 0.3C-0.8C, instant impulse discharge current
is 10C for 10 seconds.
(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 90% 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 3000 cycle times of single cell(80%DOD).
(6) It can fast charging. It could be charged to 80% within 0.5h and charged full with 2-3h.
(7) No pollution during manufacture and usage.
Requirement for safety assurance
For the sake of safety assurance, please discuss the equipment design, its system and protection circuit
of Lithium-ion cell advance. And consult about the high rate current, rapid charge and special application
in the same way.
