My old Nitro is SUPPOSIDLY sold and the guy will pick it up wednesday. I know I need 1 new battery for my TM cause when I switch from 12 to 24 volt, it does not change how much thrust it puts out. Also know that I need a new cranking battery cause just sitting for a couple days, it'll lose about 1/2 it's charge. Anything special that I need to look for on the cranking battery? What about all that banks talk for the TM battery? I'm going to get someone to look at it and install it due to the fact that I have an inline charger and it's not charging squat. I hope it's just a loose wire or something but I just don't know much bout it
