Note:

 

1. Each battery module has one slave BMS circuitry inside;

 

2. Master BMS circuitry(we named BMU) collect all information from each battery module through

 

RS485, then decide to cut-off the contactor or not;

 

3. We strongly recommend customer to use two contactors (one for charge and another for

 

discharge) in the battery system.

 

4. We can connect more battery modules in parallel to expand the system capacity.

 

 

The advantage of LiFePO4 battery compared with SLA battery:

1. Smaller size, normally 1/3 as conventional SLA battery

2. Lighter weight, normally 1/3 as conventional SLA battery;

3. Longer cycle-lifespan battery is about 300cycles while LiFePO4 battery can be 1200 cycles or more;

4. Good performance in deep discharge, LiFePO4 battery can be 100%DOD while SLA battery is 60%-80%DOD, which means LiFePO4 battery will need less capacity in the same condition;

5. The lead acid battery will be end of life and price will increase.

6. Environmentally friendly of LiFePO4 battery
