CC / CV No Memory Effect Lifepo4 UPS Batteries With Low Self Discharge
Brief introduction:
LiFePO4 battery developed and produced by Optimum use the
internationlly mature cylindrical structure design,maximizing the
performance with best battery structure, formular and material.
Meanwhile,the conformity and dependence of cell are highly improved
by improving production procedure and updated equipment. Now
Optimumnano mainly produce 32650/32750 LiFePO4 battery,striving to
maximize the power and density with identical module and dimension.

2.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.
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.
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.
3.Advantages of Optimum LiFePO4 battery :
- 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.
- 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;
- Good safey performance : no explosion and burning after safety testing like overcharging/discharging,short-circuit, dropping, squeezing,heating,penetrating,etc.
- 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.
- Small self-discharge current:rest for one month with half soc,self-discharge current less than 5%;
- High efficiency of charging: capacity efficiency ( ampere hour efficiency) usually 100%,100Ah for charging and 100Ah for dicharging;
- Good performance of heavy current: the capacity stays the same with 100% capacity when the battery discharge at different rate at 0.1C-5C.
4.Why you choose OptimumNano battery:
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.
