The use of LiFePO4 chemistry guarantees long life, operational stability, and a high number of charge and discharge cycles, while maintaining high energy efficiency. The integrated JK Smart 3S–8S 40A active BMS ensures maximum safety and intelligent cell management, which translates into longer battery life and higher system reliability.

General Description

The 12V 20Ah LiFePO4 battery with the JK Smart active BMS is the ideal solution for users looking for a modern battery with long durability and a high level of safety. Lithium-iron-phosphate (LiFePO4) technology is characterized by significantly greater resistance to deep discharge, lower self-discharge, and a significantly higher number of cycles compared to traditional lead-acid batteries. The 40A active BMS ensures even charging and discharging of individual cells, protecting them against overcharging, deep-discharging, overloading, and overheating. This solution will work well in both stationary and mobile installations, guaranteeing a stable 12V voltage and a real capacity of 20Ah.

Specific product features

• Nominal voltage 12V – the battery, built using LiFePO4 cells, ensures a stable operating voltage, ideal for use with most devices adapted to 12V systems (LED lighting, converters, pumps, consumer electronics, alarm systems, etc.).
• Capacity 20Ah – a real capacity that provides adequate energy reserves for devices operating in both continuous and cyclical modes. A battery of this capacity is ideal for small photovoltaic systems, campers, boats, caravans, strollers, etc.
• LiFePO4 Technology – high cycle count (up to several thousand in typical applications), low sensitivity to deep discharge, high thermal stability, and significantly lower weight compared to lead-acid batteries of similar capacity.
• JK Smart Li-Ion-LiFePO4 3S–8S 40A Active BMS – advanced battery management system:
  • Active cell balancer for increased battery life and long-term capacity retention,
  • Supports configurations from 3S to 8S (12V configuration used in this product),
  • Operating current up to 40A, which allows for the safe powering of devices with relatively high power consumption. power,
  • protection against overcharging, overdischarging, overloading, and short circuits.
• Safety of use – LiFePO4 is one of the most stable lithium chemistries:
  • low susceptibility to overheating,
  • no "swelling" effect characteristic of some lithium cells,
  • no gassing or electrolyte leakage, which increases safety in mobile and home applications.
• High charge and discharge efficiency – low energy losses, fast charge acceptance, compatibility with modern LiFePO4 chargers and photovoltaic systems (via an appropriate charge controller).
• Minimum self-discharge – the battery retains energy for a longer period of time when not in use, which is particularly important in systems (UPS, backup power), as well as in vehicles and boats used seasonally.
• Long-term cost-effectiveness – the higher initial cost is offset by a very long service life and lower service and replacement costs, making the 12V 20Ah LiFePO4 battery a more cost-effective solution than traditional lead-acid batteries.
