Please Idiot check my wiriing =)

First time wiring up lipos and hoping to have another set of eyes on this before I burn up my new lipos and wiring. Or tell me I am making this much harder then it needs to be.. Also any advice on the best way to charge them in parallel? I would like to balance charge them as 20ah 4s with my imax b6. Or buy something so I can balance charge multiple packs at once?

12x turnigy 4s 5ah 25-35C for 12s 20ah (500amp continues)

3x turnigy low volt buzzers set to 3.7v. 1x buzzer per 4 pack bundle

I was told 0/1awg would be overkill so thinking I will either run 2awg or 4awg.




Tested with 24v 54ah SLA batteries and she ran great.(gps 18mph) Could only do soft starts as the batteries could not supply enough amps. Hoping with the lipos under the steering wheel and the largest axle sprocket I could fit I will be able to spin the tires.

Stop: looks to me like you are about to feed 50.4 volts into a 24 volt system. Someone please correct me if I'm wrong.

You are connecting 12s in series when I think you need to connect 6 s in parallel to get 24.2 volts

As far as charging goes 6s in parrellel easily charges on any RCbalance charger.

And your 8g series connects need too be same gauge as the outputs. They see just the same amount of current. What amps are you pulling?

Correct this will give me 7500rpms. If heat does not become an issue I might move up to 16S for 10000 rpms and a good time. 8)

Thank you for the info! I will run them with 2/4awg. I have a 400amp kelly controller, but they are overrated. So most likely peak around 275-300a on take offs and average 50-100a. But will not know for sure until I pull logs from the controller or hook up an Ammeter.

What is the voltage rating for your controller?

24v-60v


More concerned about the way the lipos are wired though. Does that part look ok?

300 amps through 8g wire would give you a nice warm feeling behind your rear :lol: good thing you're beefing them up!
