Hi,
I purchased the Velleman Universal Battery Charger / Discharger kit ( K7300 ) last year and have been using it very successfully since then.
Could anybody on this forum perhaps suggest a modification that I could make to the circuit in order to be able to charge a 12V 3.4A/H NiCd battery? The kit only supports batteries up to 9.6V.
My required charging current of 340mA falls within the capabilities of the kit, but I need to make provision for the discharge cycle which needs to sense the battery voltage accurately and switch to charge mode automatically once the battery has discharged to 10V.
I believe an additional jumper and resistor of +/- 8K between R17 and R18 should do the trick, but would like to get a second opinion first before attempting the modification. Has anybody out there attempted this yet ?
Cheers
Carl.
