Recommendations

Before buying a charger, next data must be determined:

a) CHARGE CYCLE

We advise you to consider your choice of the battery, and to examine all our chargers. Every model was designed for a specific application. Before you choose, check the next points:

1. 1. Is the battery totally or partly discharged when it’s connected to the charger?
   2. How much time is there to charge the battery?
   3. Do you need a charger which can charge batteries with different tension and capacity? Contact us!

b) TENSION OF THE CHARGER

The tension of the charger must be the same as that of the battery: 2.0V per cell.

c) CHARGE CURRENT

The charge current must be chosen in accordance with the battery capacity. With charge current, we mean the current which is given by the charger when the battery is at its nominal voltage (2.0V/cell). The current decreases to 50% when the battery tension rises up to 2,4V/cell and to 25% when 2.65V/cell is reached. For example: 48V – 100A / 57,6V – 50A
/ 63.6V – 25A.

WoWa charge curve:

Equals the Wa charge curve, but the current in the principal phase is 20 to 40 % higher than by the Wa chare curve. The final charge phase is identical with the Wa charge curve.
