Deep Cycle Lithium Battery 12v 50ah For Storage Energy / Car / Solar Light
1. 12V 50Ah deap cycle lithium batteries advantage

  • Environmental friendly
  • High density of energy
  • Low self-discharge
  • Low internal resistance
  • Long cycle life of more than 2000 times
  • No memory effect

2. Specification

NO.ItemsCriteriaTesting method
1Rated Capacity50AhRest for 1 hour after fully charged, then discharge with 0.33C current until the battery reaches the discharge cutoff voltage. Repeat above process for three times, if the discharge time is not less than 120 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity.
2Minimum Capacity50Ah
3Internal resistance≤40mΩ50% battery SOC state frequency of 1 KHZ ac resistance tester
 Short circuit protectionYesConnect the positive and negative of this battery pack through a lead with the resistance less than 5mΩ.

Cycle life

≥2000cycleDischarge with the current of 0.33C until it can’t discharge, and then rest it for 1h. Charge the battery following CC(0.33C)/CV(14.6V) mode to full capacity, and then rest it for 1h. Repeat above process until full charged capacity is no more than 80% of normal value. Accumulated times is defined as cycle life.

Discharge Temperature

-20℃≥70%At 25±5℃ discharge the battery with the current of 0.33C to the cut-off voltage and record charge capacity. Store the battery at various temperatures for 2h and discharge the battery with 0.33C to the cut-off voltage.
7Charge Retention ability


Charge the battery to full capacity and store it for 28days, and then discharge it with 0.33C to the cut-off voltage.
Recovery capacity≥90%

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 overdischarge 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.
