3. Why you choose OptimumNano battery:
Advantages of LiFePO4 battery
Safety
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%.
