About 12v 7ah rechargeable lithium ion battery

12v 7ah lithium ion battery apply with high-quality 3s Lithium ion battery cells, the battery system come with built in BMS. Total energy 85Wh.

12v dc battery pack structure.
The 12v battery bank build by 3S BMS. can effectively charge and discharge the battery pack . The BMS prevent any battery overcharge, over discharge caused by damage, And can control the battery charge, discharge current,Ensure that the battery pack and applications are not damaged;To ensure that in the event of a short circuit failure when the output off and automatic balance of the application of the battery pack at any time in the best condition. The 12v 7ah 20hr rechargeable battery also come with ABS battery casing. Provide strong protection from any physical damage.

Safety and economical

lithium 12v 7ah battery with Newest ICR18650 cells. Battery cell is tested before assemble. It does not have toxic chemicals and offers four times the power density at a third of the volume compared to lead acid. For these reasons it’s safe for household use.

Excellent discharge characteristics

lithium ion 12v 7ah With low internal resistance and high, flat voltage characteristics during strong current discharge, which ensures a wider application field. Like UPS/Solar System/CCTV System

Long cycle life

12v 7ah lithium ion battery Provide long storage life with few limiting conditions. It offers problem-free charge after long storage, permitting to use in a wide range of applications.

Safty Test:

  • Over-charge test
  • Over-discharge test
  • Short-circuit test
  • High-temperature test
  • Fire test
  • Squezzing test
  • Pin-Prick test
  • Fall down test
  • Water immersion test
  • Shooting test

lithium 12v 7ah rechargeable battery BMS protection

Overcharge protection: When the battery is under the charging state, the voltage keeps going up. When the protection board detects that the voltage of any cell is higher than the overcharge protection value, the protection board will start timing immediately. When the time reaches the overcharge protection delay, the protection board will turn off the charging MOS tube, at that time, it cannot be charged.

Overcharge protection recovery: After the overvoltage protection appears on the protection board, the battery voltage will going down under the static or discharge state of the battery. When the protection board detects that each voltage is lower than the recovery voltage of the overcharge protection, the protection board will output a signal and turn on the charging MOS tube to charge.

Over-discharge protection: When the battery is under the discharge state, the voltage keeps going down. When the protection board detects that the voltage of any cell is lower than the overcharge protection value, the protection board will start timing immediately. When the time reaches the over discharge protection delay, the output signal of the protection board will turn off the discharge MOS tube, the load lock circuit will work, but, it cannot discharge at this time.

Over discharge protection recovery: After the over discharge protection appears on the protection board, the battery voltage will going up under the static or discharge state of the battery. When the protection board detects that each voltage is higher than the recovery voltage of the over discharge protection. At this time, disconnect the load or charge, the protection board will output a signal and turn on the charging MOS tube to charge.

Overcurrent protection: When the battery is under the static or discharge state, the current suddenly increases. When the protection board detects that the current reaches the overcurrent protection value, the protection board will start timing at that time. When the current duration in the circuit reaches the overcurrent protection delay time, the output signal of the protection board will turn off the discharge MOS tube, and the load lock circuit will work. At this time, the discharge cannot be conducted.

Overcurrent protection recovery: After the discharge overcurrent protection appears on the protection board, the discharge MOS tube is turned off, and the current in the loop becomes 0. At this time, the load is disconnected or charged, the output signal of the protection board will turn on the discharge MOS tube to discharge.
