LiFePO4 12v 40ah lithium ion battery 12v 40ah exide ups battery Storage Battery 

Product details:

12V40Ah Solar Battery Pack with SLA Case

Usage Notes:

Our 12V40AH module, with nominal voltage of 12V and capacity of 40Ah is assembled with high power LiFePo4 cells.It can be used individually and can be connected in serial or parallel to achieve given voltage and capacity.

 

Features:

a. Extremely safe and stable chemistry: PCB and/or BMS built inside to balance protect the battery.

b. Long life-cycle: Can be circularly used, best can up to 2000 times recycles, 8 times of Lead acid battery.

c. Lighter weight, with the best power-to-weight ratio: 1/3 of Lead acid battery weight.

d. Good performance at high temperature and high temperature resistance

e. Low self-discharge rate, less than 3% monthly.

f.  No memory effects and highly efficient charge.

g. Environment friendly: Clean and Green energy poses no pollution on our environment.

Advantage:
 

1.Long life, large capacity and good shock resistance

2.Low self-discharge and good discharge performance at low temperature

3.Strong charging acceptance and quick-charging capability

4.Strong over-discharge resistance and charge retention

5.Maintenance-free and no acid or water for maintenance in usage

6.Excellent large current discharge performance, and have obvious advantages in startup and climbing

7. High temperature performance

8. Environmental friendly

9. Lighter weight smaller size

 

BMS:

Our BMS consists of Master BMS Circuitry (we named “BMU”), Slave BMS Circuitry (we integrate it into our battery module) and contactor.

 

Besides the basic functions such as over charge/ discharge, over current, short circuit, over temperature and balancing, Our BMS owns the following features,

 

1. Master-Slave architecture makes the system flexible;

 2. Two level warning makes maintenance easier;

 3. CAN2.0 and industrial level electronic components make system reliable;

 4. Contactor makes high rate charge & discharge feasible;

 5. Periodic insulation measurement makes personnel safety possible;

 6. Host can control the system easily;
