    AA battery holders for 6V light overvolt.

    I have old 6V system and want to overvolt it with 6 NiMH rechargeable batterys for 7.2V. Will either one of these work these work?

    Yes. How would they not? The first has terminals for a 9V type battery connector. The second has wires terminals. Looks like they also have the first available with wire or solder tabs terminals.

    Yes, those holders will work. You probably will need to add tape or rubber bands to keep the cells from rattling loose and breaking the circuit.

    Bear in mind capacity is pretty low, something less than whatever each cell is rated, typically 2000-2500ma. For example, a 15W/6v MR11 halogen lamp will burn only an hour on this power supply. You'd need 2 cell holders and 12 AA cells to ride for 2 hours.

    I will probably only run a 6 watt flood on the bar for supplemental lighting and a backup for my Gemini Titan headlamp. I have a 6. 10 and 15 mr11 lamps. Thanks for the input.

    If you are going to overvolt to 7.2V anyway why not go with Lithium Ion or Lipo batteries? The voltage will be the same and capacity will be far higher per unit of weight. You will need an protection PCB to protect the batteries from overdischarge though.

    Cost, cheap battery's and I already have AA Ni-MH chargers.
