Li-Ion battery 12V 13Ah (3s4p)

The rechargeable battery (ACB) is designed for stable output of high capacity during repeated deep charge-discharge cycles in electrical systems with a constant voltage of 12V. For safe operation, monitoring and control, the battery is equipped with a BMS (Battery Management System). The BMS system provides: passive balancing of cells, control of charging and discharging conditions (by voltage and current), temperature control.

  • Maximum charge voltage: 12.6V
  • Maximum charge current: 5A;
  • Maximum discharge voltage: 8.25V;
  • Maximum discharge current: 10A;
  • Element type: Li-Ion 18650;
  • Element diagram: 3S4P;
  • BMS type: 3S 25A passively balanced or active balanced;
  • Additional charger connector: 5.5x2.1;
  • Charge status indicator: LCD display;
  • Additional outputs: no;
  • Material: ABS plastic;
  • Size: 90x70x100 mm;
  • Weight: 640 g.

Operating features:

  • When charging the battery, connect the charger connector to the battery first and then to the AC outlet;
  • After the battery is fully charged, turn off the AC power and then disconnect the battery.
  • If you first disconnect the battery pack from the charger during charging, especially when the charging current is high (red light), the charger can be easily damaged.
  • When the charger's LED indicator turns green, continue charging for 2-3 hours to balance the battery cells.
  • Please use the charger and battery in a dry place, avoid overheating and hypothermia.
  • Please try not to charge the battery immediately after the battery is depleted. Let it cool down.
  • Please do not charge the battery while it is being discharged. Otherwise, you risk damaging the battery.
  • Do not discharge the battery below the discharge voltage limit specified for the specific battery.
  • If you need to store the battery for a long time, leave the battery 40-50% charged.
  • Please do not use Li-Ion batteries in lead-acid UPS/Inverters without deep modification of the latter. Use a LiFePo4 battery and there will be little modification to the UPS/Inverters.
