Freezing batteries - not with LiFePO4

Freezing batteries - not with LiFePO4

The lead acid battery will freeze when fully discharged. See this: The electrolyte of a fully charged lead-acid battery with density of 1.28 g/cm3 changes the structure to solid at -68°C. With density of 1.25 g/cm3 (slightly discharged battery), t

The 24V/200AH battery pack with CBM

Our customer reference photo - the battery pack with 2x 100AH cells in parallel. The configuration is 2P8S. The balancing is done using the CBM boards, 3 CBMs for each dual-cell.

TEST: The Winston LiFePO4 cell 160AH short-circuit at 1000Amp for 13 minutes

This test proves the safety of the LiFePO4 technology: no fire, no uncontrolled explosion into in fire, no sparking, no burning, no fire smoke (black).

Testing the ESS solution - 1.5 MegaWatt of cycled storage reached

We keep running and testing the Energy Storage Station. During each cycle we store and release about 5 kWh of energy. For testing we make 3 cycles a day. In the last 100 days we made 300 cycles already and stored and released the

The Energy Storage in Action

See the testing results of the . Our 5 kWh energy bank is working at 3 cycles a day. This means we store and release 15 kWh energy in a day.

We use to monitor the AC power of the solution.

Is there a difference between 100Ah and 100Ah?

Is there a difference between 100Ah and 100Ah?

The test data prove quite some difference in the performance of LiFePO4 cells from various manufacturers. This test shows the difference between the discharge results of GBS 100AH and WINA 100AH.

The discharge times at 1C (105Amp) from full charge to 12V a

Safe Disposal of Damaged Batteries

Safe Disposal of Damaged Batteries

Some times it happens that the LiFePO4 cells or batteries get damaged due to an improper use such as deep discharge or over charge. Such cells or batteries cannot be repaired and must be disposed of properly. If necessary, to dispose of damaged batteries
