12V 40ah LiFePO4 Battery for Car Starting Engine

Lithium iron phosphate batteries (LiFePO4 or LFP) offer lots of benefits compared to lead-acid batteries and other lithium batteries. Longer life span, no maintenance, extremely safe, lightweight, improved discharge and charge efficiency, just to name a few. LiFePO4 batteries are not the cheapest in the market, but due to a long life span and zero maintenance, it’s the best investment you can make over time.

Major advantages of Lithium Iron Phosphate (LFP Battery or Lifepo4 Battery).

• Very safe and secure technology (No Thermal Runaway)
• Very low toxicity for the environment (use of iron, graphite, and phosphate)
• Cycle life: from 2000 に 4500 times (see chart below)
• Operational temperature range: up to 70°C
• Very low internal resistance. Stability or even decline over the cycles.
• Constant power throughout the discharge range
• Ease of recycling
• RS485 and RS232 communication output

Our Line of Lifepo4 Batteries offers a solution to demanding applications that require a lighter weight, longer life, higher capacity battery, high safety. Features include advanced battery management systems (BMS), Bluetooth and CAN bus Communication, and active intelligent monitoring.
