    3. Deep cycle rechargeable lithium battery 12V 20Ah dimension

    Topband Deep Cycle Lithium Battery 12V 20Ah over 2000cycles @ 100% DOD

    4. Deep cycle lithium battery advantage

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