Deep-cycle 12V LiFePo4 Battery

Deep-cycle Grade A Maintenance Free Lifepo4 Battery 12V24Ah for Servers Backup Power UPS Solar Energy Storage Systems

Why should you choose a LFP battery?

Compared with other lithium ion batteries, LiFePO4 batteries have the following five advantages:
1. Stable structure and higher
security.
2. TheLiFePO4 battery has a cycle life of at least 3000 times, and its capacity can be maintained at more than 80%.
3. Environmentally friendly materials is applied.
4. Support fast charging, max. 0.5C .
5. A wider operating temperature range, which can work normally from -10℃ to + 65℃

Warning and Caution

•  Do not submerge the battery pack in water or get wet in the rain, keep the battery in shady and cool place when stored.
•  Do not charge the battery continuously over 24 hour.
•  Do not discharge the battery pack continuously when charging it.
•  Do not drive a nail in battery pack, hit the battery pack with a hammer, stamp on or throw the battery pack.
•  Do not disassemble or alter the batteries’ outside structure.
•  Do not use the battery pack under blazing sun, otherwise it may cause battery pack overheating then catch fire or function failure.
•  Do not put the battery pack into fire or heat the battery pack; do not store the battery pack in high temperature environment
• When charging or discharging the battery pack, if you find any abnormal smell or noise, you must stop the charging or discharging at once, and contact the manufactory.
• When using the battery pack out of range of 0~30℃, the capacity may decrease, that doesn’t mean the battery pack was failure.
• There is a protective circuit inside the battery to prevent contingency. Do not use the battery in the place of static electricity, (above 1000V), for it is easily destroyed the circuit board so that the battery doses not work and causes over-heated, distort, smoke or burning.
• Do not connect the battery pack's positive (+) and negative (-) poles reversed to charger or load, Do not connect the battery pack to charger's input power source (AC power supply).
• Do not let the battery pack's terminals (+ and -) contact with unnecessary wire or any metal or stored them together, that may cause the battery pack short-circuit.

Electrical propertie

After standard charging, laying the battery pack 0.5～1.0h, then discharging at 6A to ending voltage, record the discharging time.
Criteria: 240min

Discharge at low temperature
After standard charging, laying the battery pack at -10±2℃ for 16h, then discharging at 6A to low temperature discharge ending voltage, record the discharging time.
Criteria: ≥96min

Discharge at high temperature
After standard charging, laying the battery pack at 60±2℃ for 2h , then discharging at 6A to ending voltage, record the discharging time.
Criteria: ≥192min

Cycle Life
After standard charging, laying the battery pack 0.5～1.0h, then discharging at 5A to ending voltage,laying the battery pack 0.5～1.0h again, Repeat these steps above till two consecutive discharging time less than 168 minutes,record the cycle count.
Criteria: ≥ 2000 times

Charge retention
After standard charging, laying the battery pack 28 days, then discharging at 6A to ending voltage, record the discharging time.
Criteria: 96 min
