Re: wiring up batterys

Wire them in series.


With Batteries:
Series ups the voltage
Parallel ups the capacity

i have had sucess in wiring up three batterys, i now have 23 volts, but i think i may have a problem now with charging it, do i need a 24vovt charger now

Either that or use connectors to attach them together then take them all apart to charge.

No, you charge the 3 packs individually. You can get chargers that will charge the lot in one go however because you have more wire between some of the cells in the batteries you have a greater resistance. This can create an imbalance in the pack when charging. Not as much of an issue with Nimh but I would always recommend charging the 3 packs separately
