I bought my gf an rc

[Ozwynn]

I got my gf an rc for Christmas. Just a cheap thing for $90. Has 1 motor on each axle and came with this junk Ni-Hi battery pack made from 6x 1.2v AA batteries with a 40 min run time and a 5-6 hour recharge time.

My question is can I replace the battery pack with 2x 18650 3.2v lithium batteries so I can have high capacity and high drain battery pack with 3-4 times the run time with a 1 hour recharge time (I have a Butt load of 18650 batteries and 2 port battery trays).

If my current battery pack is 2200mah and 7.2v… then which 18650 batteries should I use?

The RIGHT thing to do with RC's is to immediately rip out all the stock electrics and replace them.

Hobbywing sells real affordable brushless/lipo setups. The receiver is probably built into the stock speed control.. so look at flysky for an affordable tx/rx. Then it's whatever battery/charger you want.

I don’t know if I can do that.

I don’t know if I can do that.

Not with that attitude you can’t.

Hmmmm. With enough ingenuity anything is possible! Guy I work with built a rock bouncer in the same scale from scratch by soldering together brass rods for the chassis and links and using some spare axles and stuff he cannabilized from another truck.
