3.2V Deep Cycle Lithium Battery Module LiFePO4 2000 Times Cycle Life

3.2V Deep Cycle Lithium Battery Module LiFePO4 2000 Times Cycle Life

1. Lithium battery module feature

• 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.
• 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.

2. Lithium battery module can be assembled with various cells,

Available to make all customzied battery pack. Cell's details as below:

3. Safety Characteristics

• Over-charge/Over-discharge Ability to withstand over-charge/withstand over-discharge, and there is no fire, no exploding and work well
• Short circuit Ability to withstand short circuit, and there is no fire, no exploding
• Acupuncture Ability to withstand nail puncturing, and there is no fire, no exploding
• Thermal shock Ability to withstand thermal shock, and there is no fire, no exploding

4. Our Service

• Fast Delivery, can handle shipping for customer if needed
• Samples are available with charged
• 2 years warranty
• Every battery pack can be customized according to your specific demand. OEM is acceptable.
• Expertist technical support and good after-sales service

5. Battery operation instruction

• Charging current:Do not surpass the largest charging current that specification stipulated.
• Charging voltage:Do not surpass the highest limited voltage that specification stipulated.
• Charging temperature:within temperature scope that specification stipulated.
• Charge with constant current, then with the constant voltage, no reverse charge, which is dangerous
• Special note: Short time doesn't affect the use of the battery overcharge too, but for a long period of time over discharge or over charge can affect the function of the battery failure, or the battery can't use permanent, appear serious safety hazards, need long time floating please use the recommended floating model specification.Battery when not in use for a long time, because of its own self-discharge characteristics can also cause discharge, to prevent the occurrence of a discharge, battery should maintain a certain capacity, maintain the voltage at 50% state of SOC.
