Advantages of LiFePO4 battery

The chemical structure of LiFePO4 is very stable

-- Long life cycles
>2000 times cycle life at 0.1C-1C discharge/charge rate

-- High energy density
Energy density: 135 Wh/kg
Weight: 1/3 of lead acid, 2/3 of Ni-MH
Volume: 2/3 of lead acid

-- Wide Temperature range
Working temperature range: -20° C--70° C
Perform good in high temperature: Reach 350° C-500° C in peak, about
200° C for LicoO2 and LiMn2O4

-- Fast charge
1C standard charge and discharge, above 93% of the capacity during 3.3~3.2V platform
Steady charge and discharge platform, can reach high current power charge and discharge
Good at high discharge rate, above 96% charge and discharge efficiency by 10C

-- Less self-discharge
Self-discharge<3%(month), while the monthly self discharge of sealed lead acid battery is 10%.

-- Environment friendly
Optimum LiFePO4 battery has great efficiency for energy conservation and emission reduction,
Without any hazardous and noxious substances

It according to customer's need:
Carton or wooden case
1. PVC film
2. Epoxy board+ PVC film
3. SLA case
4. Customized iron case or aluminum alloy case
Shipping: International express, by air, by sea
