Features of Optimumnano LiFePO4 battery pack:

1. Pack assembly technique: Use the most mature cylindrical structure design 32650
LiFePO4 battery, making use of assembly technique developed by us to form products of
Different modules required by customers which are against dust, water, vibration and good
In conductivity and heat raleasing. At present, the maximum capacity of module we've
Produced so far is 900Ah while maximum voltage of pack is 600V;
2. Battery management technique: Self-developed BMS, automatic testing voltage,
Temperature, current, insulation level and SOC, use advantage lossless balancing function
And GPRS wireless data transmission function.
º 3. Ensuring of best performance of each cell;
4. Seamless exchange: We can produce packs that are the same with lead-acid battery in
Voltage, capacity and dimension, without changing the mould.
5. Lighter, smaller and stronger: Optimumnano LiFePO4 battery pack system is featured
With lighter weight, smaller dimension and stronger power with service term above 10
Years.

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.
