I have a place in England that can build custom batteries. 5x2 NiMi 2600mah with three leads red, black and yellow for the center tap. I also found the connectors for these batteries. The place for the batteries is
www.componentshop.co.ukemail kyje@componentshop.co.uk Ask for 5x2 NiMi batteries with six inch leads, red for positive, black for negative and a yellow wire for a 6V tap.
The connectors are available from JST
ECK-03V
ELP-03V
Pins
Male SZF-01T-0.7
Fem. SZM-011-0.7
Batteries are approx. 21.00 U.S. 28 GPB
Coonectors I received samples so do not have a cost.
Hope this helps.
As to the charger, pretty much any 12V charger will work just using the positive and negative connections,
Lou
