Hey Bean. You have a link to these Rc batteries you use?
I usually get them on ebay and get 4 batts at a time. they usuially sell (3) 7.2v NIMH rc batts for around 50 shipped. I was looking on ebay a few months ago and noticed that 1-2 companmies are now selling (4) at a time instead of 3
Theyre just your average cheapie 7.2v NIMH rc batts
When I got them all in summer 2005 tho, I did notice somethinga nd am just forewarning you. It took AT LEAST 6-7 cycles to get my NIMH rc batts to reach their maximum capacity tho FWIW. not a huge deal but I thought I got (12) BUNK batts. after 6 or so cycles I realized they were fine
and with NIMH, no memory effect even tho I do cycle them completely about once a year even tho there is no memory effect. I feel better and safer cycling them at least once a year so I know thjey are at 100% capacity
Mark, search ebay for 7.2 volt NIMH batteries and if that doesnt work try switching up your search terms, becuase it takes a few times of getting your search words just right for the NIMG rc batts to pop up so........
