Velleman K7302 Battery Charger

Hi All,

Can any of you advise on the use of the universal battery charger K7302 please?

I would like to use it to charge either 6 or 8 AA NiMH batteries while external power is applied, but when it isn’t, for the batteries to operate the game when switched on.

My intention is to wire the unit, linking the input power to the input of the K7302 and then use two 1N4001 rectifier diodes to prevent reverse feeds.

Layout and basic diagram attached.

Any help, guidence is appreciated.
