Quality features of optimumnano LiFePO4 battery pack:

In optimumnano, each cell and pack is produced with the principle of "conformity in 6 aspects and 3 inspections in 3 stages", thus the high stability and reliability can be guaranteed. "Conformity in 6 aspects" is a principal developed by optimumnano's engineers in production and inspection process. The application of ensures conformity of packs and improves service term of pack obviously. And "3 inspections in 3 stages" refers to inspections on battery assembly, paralleled modules and finished packs.

The feature of LiFePO4 battery
1, Safe: The iron-lithium battery is more safe and reliable than the lead acid one. It does not explode or burn when bump, heavy stress, needle pricking, short circuit, overcharge and overheat.
2, Environment-friendly: Accredited with RoHS, without any hazardous and noxious substances.
3, Small in volume and light in weight: The iron-lithium battery is about 1/2 the volume and 1/3 the weight of the lead-acid battery.
4, Powerful: Able to discharge with 20C at 65. C max.
5, Steady performance: High power output: 1C, continuous: 3C pulse for normal cells and 20 C for special design. Low self-discharge rate, less than 3% monthly.
6, Long cycle life: Over 2000 cycles with capacity staying at 80% min.
7, Lower average price per year: The average price per year is 100 Yuan RMB less than the lead-acid battery for 5 years.
8, No memory effect: Always ready for charge and use, with no need to charge after a full discharge.
9, Wide temperature range: Available for use when the temperature ranges from -20° C to 70° C
10, Intelligent charge system: Voltage of each cell can be detected. Each cell can be protected against overcharge, overvoltage, short circuit and overheat, and so that battery can be charged balance. The capacity of readout power volume: Each battery has 5LED lights to readout the capacity of the battery.
