What batteries to use?

[Technic Jim]

Hello all,

Recently I have purchased two RC motors, a RC unit and a controller. I have had some good fun playing around with it but I seem to be spending a fortune on non-rechargeable, 1.5V batteries. I know that this isn't the best idea but I have bought some standard 1.2V rechargeables and they can't seem to power the motors. I know that most people use eneloop pro batteries but I'm not sure whether or not they'll work. Another idea which I had was to use 1.6V Ni-Zn rechargeable batteries but I'm not sure if the rc unit will accept them. If you have any ideas, they would be appreciated.

Thanks for the help, Jim

from what i've heard, eneloop batteries are something reliable, but i've never tried them, I also have the same problem (with 2500mah energizer 1.2V) they last not really less but with less power, because of the voltage, for the 1.6V batteries I think that you should search for what is the maximum voltage at full charge, and if it is like an alkaline one (it could be near their voltage) and so you can use it safely

I relie on Eneloop rechargable batteries or the Amazon Basic rechargable batteries (the white ones as the are just rebranded Eneloops). I thought about those relative new Ni-Zn batteries. But according to my web research they seems to be quite expensive (you need a new/special charge and the batteries are not cheap either) and not very reliable.

Eneloops may have lower initial voltage but they hold the current for longer.

You could consider wiring up an extra 1.2v rechargable in series with the 6 already in a battery pack, not pretty, but some handiwork with simple wires, electrictape and perhaps a piece of alu foil will bumped the voltage coming out of the batterypack to 8.4v compared to the 7.2 6 of those rechargeables produce.

Bumping it to 9.6 by adding not one, but two extra in the circuit would probably be safe as well

Not the cleanest mod mind you

Thanks for all the help guys. I'll probably buy some eneloop pro batteries and use them instead of the 1.6v and perhaps try a bit of modding to increase the voltage.
