4. Deep cycle lithium battery advantage

Output with high efficiency: Standard discharge current is 0.3C-1C, pulse discharge current is 3.5C for 3 seconds.
Good performance under wide temperature -20-60℃. The battery structure is safe and good.
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.
Long cycle life time, the discharge capacity is still over 80% after 2000 cycle times of single cell(100%DOD).
It can fast charging. It could be charged to 80% within 20 minutes and charged full with 2-3h.
Low self-discharge. Less than 3% per month.
No pollution during manufacture and usage.
