Anyway, that doesn't help me with the question I asked. I knew about LiFe batteries (Route 246), and I also know that they cost around 15$ each, and I need two plus the wire to use them in parallel. That's +32$ just for one pack of batteries.

I'm from Spain, and here it's not easy to find "rare" batteries. Can't find Route 246, mush less those Eagle Racing you use.

LiPo batteries cost 3$ and the car runs with just one, because they are 2S. I know they are 7.4v, that's why I use a UBEC to get that voltage down to 5v that is close to the 4.8v of the AAA batteries. Maybe I'm wrong thinking that a UBEC can do the job I need, that's supply the motor with enough "juice" to run. This is what I need to know.

Now that I say this, I'm noticing that AAA batteries when charged have around 1.4v-1.5v. Does the ASF electronics have any kind of low voltage protection?

I don't want to sound ungrateful for your answer "targetingxmod" (I thank you for your time), it's just that after all that time, you only give me the commercial solution that I already knew of.

I'm tired of only "playing" with Kyosho solutions, they are overpriced. This is a project. If I can get this to work, I can spare myself the pain of checking AAA batteries at my local club to help people to find out why their Mini-Z doesn't go as fast as before, and then match batteries to make packs.

I race with my Atomic AMZ, and soon with my BZ, as soon as it arrives. Xmods wasn't my "cup of tea".

Thanks again.
