Log in to purchase

ELB300 is designed for new energy batteries such as lithium iron phosphate, ternary lithium and lithium manganate, and can quickly solve the cruising range degradation caused by the difference in cell capacity due to inconsistent cell voltage.



Our high-voltage battery cell equalizer is an extremely useful tool that allows you to test, charge and discharge individual cells. It offers you the possibility to bring the voltages of all cells to a uniform level.




Uniform charging or discharging of the cells

Overcharge or over-discharge

Effectively prevents overcharging or over-discharging of any cell in the HV module.

Charge and discharge equalization

Independent channel design that detects and uniformly charges or discharges the cells in the module. When charging or discharging, it ensures that no cell in the module is overcharged or over-discharged.

Safety protection function

Protection against overvoltage, undervoltage, overcurrent, short circuit and reverse polarity protection.

Equilibrium maintenance present

The balance maintenance parameters can be set as required. This allows the balance to be quickly maintained according to the current parameters.
