Rechargeable Lithium Battery 12.8V 40AH LiFePO4 Battery to Replace The Lead Acid Battery

Product Strong Functions

• High voltage platform, average voltage battery is 3.2V;
• High power density, light weight, average 1/3 weight of lead-acid batteries;
• More than 6 years of service. 3,000 times of charging and discharging with 1C DoD;
• High power endurance, battery can be charge and discharge in 0 ~ 30C, which is convenient to high strength start-up and acceleration;
• Low self-discharge rate : ≤ 1%/ month;
• Wide working temperature, easy run in low or hot temperature environment(-20ºC ~ 90ºC );
• Green environmental protection, no matter in production, use, and scrap, do not contain lead, mercury, cadmium and other toxic and harmful heavy metals and substances;
• No gas in charging and discharging, the current efficiency is close to 100%.

Major parameters of protection board:
1. Overcharge protection: Starting protection in the voltage range of 15.0v -15.6v,resume normal under the voltage 15.0v.
2. Over discharge protection: Starting protection in the voltage range of 8.0v-8.4v,resume normal over 8.4v.
3. Short circuit protection: Starting protection when short circuit,switch off the load,resume normal.
4. Average voltage: average 3.6v voltage per cell.

Lithium Iron Phosphate (LiFePO4, LFP) is kind of Li-Ion rechargeable battery for high power applications, such as EV , Energy storage, Power Tool and so on. LFP cells feature with high discharging current, non explosive, long cycle life (>2000@0.2C rate, IEC Standard), but its energy density is lower than normal Li-Ion cell (Li-Co) (higher NiMH cell). Please click Knowledge on LiFePO4 battery to learn more detail. LFP cell has 3.2V nominal working voltage and shall be cut-off power at 3.6-3.8V per cell during charging. Please see the table below to see comparison between LFP and other rechargeable batteries. LFP battery has the lowest cost if considering its long cycle life.
