6. Connection mode for parallel communication

6.1 RS485 Parallel Communication

While in RS485 parallel communication, dial-up addresses of battery module are 1,2,3,4……14,15; By this method, we can be allowed to read each data depending on battery module. Any battery other than address 0 can be connected to the host computer; FF polling mode used as consulting mode.

LiFePO4 Battery

Note: RS485 communication address can not be 0, the address set by the host computer is required to be the same as the battery communication address, do not have duplicate addresses, otherwise communication may be affected.

8. Standard Test Condition

Test should be conducted with new batteries within one month after shipment from our factory and the cells shall not be cycled more than five times before the test. Unless otherwise defined, test and measurement shall be done under temperature of 23±2C and relative humidity of less

75%.,air 86Kpa~106Kpa.

Unless otherwise defined, 30min,rest period after charge,30min,rest period after discharge.

9. Storage and Others

9.1 Long Time Storage

If stored for a long time(don’t used,exceed three months), the cell should be stored in drying and cooling place. The cell’s storage voltage should be 51V-53V and the cell is to be stored in a condition that the temperature of 23±2C and the humidity 0f 45%- 75%. Long-term use of unused batteries to recharge every 3 months 。Ensure that the battery voltage is within the above range。
