good dual batt instructions
 

go to minircmod.com and click on support good pics and instructions and if your lazzy you can buy one already done for 30 bucks. with the zip i would out the second batt inside unless you just have to do wheelies

That is a pretty good info site. I ganked some of their images for my FAQ. Shhhh, dont tell on me. ;)

i was going tell ya but i didnt know about legality of that so shh i want tell! hahah it will be good on the faq. good job there as well

Ok, these instructions are better but I'm still confused. Why does this mod need a 4.5 volt charger when 2 bats in a car = 3 volts? If this way is correct, then why is the mod on the well respected qfm site still up? Which one is correct? The QFM site only uses 2 batteries in the charger. This new site states that 3 batteries are required. What gives?

I would imagine they use a 4.5v setup to minimize charge time?? I dunno, I'm no electrical wiz.

I still dont get it. Can someone explain why the difference.
