3.2v 100ah Rechargeable Lithium Battery Electric Bicycle Lifepo4 Cell
Overview:
LiFePO4 battery developed and produced by Optimum use the internationlly mature cylindrical structure design,maximizing theperformance with best battery structure, formular and material. Meanwhile, the conformity and dependence of cell are highlyimproved by improving production procedure and updated equipment.Now Optimumnano mainly produce 32650/32750 LiFePO4 battery,striving to maximize the power and density with identicalmodule and dimension.
Features:
1.High dimension ratio power: 32750-7Ah weight ratio power is 135Wh/kg,dimension ratio power is 370Wh/L; 32650-5Ah weight ratio power is 110Wh/kg,dimension of ratio power is 370Wh/L.
2.long cycle and service term:1C charge/discharge,100% discharge depth,80% capacity after 2000 charge/discharge cycles. sevice term above 8 years on ev;
3.Good safey performance : no explosion and burning after safety testing like overcharging/discharging,short-circuit, dropping, squeezing,heating,penetrating,etc.
4.Good performance at high or low temperature:105% capacity can be released when charge/discharge at 55 °C;80% capacity can be released when charge/discharge at -15°C.
5.Small self-discharge current:rest for one month with half soc,self-discharge current less than 5%;
6.High efficiency of charging: capacity efficiency ( ampere hour efficiency) usually 100%,100Ah for charging and 100Ah for dicharging;
7.Good performance of heavy current: the capacity stays the same with 100% capacity when the battery discharge at different rate at 0.1C-5C.

Quality features of optimumnanoLITHIUM( 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.
Application:
1. Large-scale electric vehicles: electric bus, electric car, E-Tour Car
2. Light electric car: e-bike, electric scooter,e-motor, electric golf car, forklift, cleanness car, electric wheelchairs
3. E-tool: electric drill, electric saw, lawn mower and so on
4. Remote control cars, boat, aircraft, toys
5. Solar and wind power generation energy storage devices
6. Small medical equipment and portable equipment.
