Traditional lead-acid batteries are heavy, short cycle lifes. Egber 12V lithium iron phosphate (LiFePO4) batteries are specifically designed for lead-acid to lithium conversion – they share compatible dimensions and electrical parameters, allowing a direct drop-in replacement without modifying your existing system.
Higher energy density – At the same capacity, weight is only 1/5 ~ 1/6 of lead-acid (e.g., a 12V 100Ah lithium battery weighs just 10.5 kg)
No memory effect – Charge anytime without needing full discharge
Ultra-low self-discharge – ≤5% per month, stays ready after long storage
Wide operating temperature – Discharge from -20℃ to 60℃, reliable even in cold regions
No gas emission – No hydrogen produced during charge/discharge; current efficiency near 100%
Exceptional cycle life – >3,000 cycles at 0.2C 80% DoD – 3 to 5 times longer than lead-acid
All models below are 12V LiFePO4 battery packs, ideal for solar storage, RVs, golf carts, electric wheelchairs, UPS backup, security systems, marine equipment, and other lead-acid replacement applications. Every battery features IP65 water/dust resistance, a flame-retardant ABS case, and a 5-year warranty.

Every Egber 12V lithium battery is equipped with a high-performance intelligent BMS (Battery Management System). The BMS ensures perfect compatibility with your existing charger and loads while providing multi-layer protection:
Overvoltage & undervoltage protection – Prevents overcharging or deep discharging of individual cells and the entire pack
Overcurrent protection – Safeguards against excessive charge/discharge currents
Short circuit protection – Instantly disconnects the circuit to prevent fire hazards
Temperature protection – Automatically pauses charging (0~45℃) and discharging (-20~60℃) outside safe ranges
Peak buzzer alarm – Audible alert for abnormal conditions
Automatic thermal regulation (optional) – Built-in heating pad at the bottom + cooling fan in the case. The system automatically preheats the battery in low-temperature environments (down to -20℃) and activates the fan when temperatures are too high, ensuring reliable cold weather lithium battery 12V performance.
The BMS also supports high-precision data sampling and fast response. Optional LED indicators or Bluetooth module allow you to monitor voltage, current, temperature, and cycle life via a smartphone app.
Check dimensions – Compare your existing battery compartment with the dimensions in the table above. Some models may require a spacer or minor bracket adjustment.
Verify your charger – Egber 12V lithium batteries require a charge voltage of 14.6V (CC/CV). If your original lead-acid charger outputs 14.4V–14.8V, it can be used. Old constant-voltage chargers (13.8V float) may not fully charge the battery – consider replacing with a lithium-specific charger.
No wiring changes needed – Simply connect positive to positive, negative to negative. Use insulated tools for safety.
Parallel connection – Up to 4 identical Egber 12V lithium batteries (same batch) can be connected in parallel with manufacturer approval to increase total capacity.
Do not mix batteries – Never connect batteries of different brands, capacities, ages, or chemistries in series or parallel.
Long-term storage: -10℃ to 35℃, dry and ventilated. Recharge to 50%~80% SOC every 6 months.
Do not expose the 12V lithium battery to temperatures above 60℃ or open flames.
If the case is damaged and electrolyte (LiFePO4) leaks, flush with plenty of clean water and seek medical attention.
Only brand new Grade A cells – No recycled or low-quality cells
5-year warranty – Design life >10 years
Certified – ISO9001, CE, RoHS, UN38.3
OEM/ODM available – Custom capacity, housing, communication protocols, etc.
