Starting Point

I thought that the battle switch acted as a relay and could only relay up to 10A where as the motor could draw way over that. So didnt see how i could get away with 1 battery. Any chance of a quick paint job wiring diagram like mine?

Also i will need atleast two batteries, for running the motors at 14.4v and the axe at 28.8v. I know my 14.4v powers the wotty which inturn powers the reciver which inturn switchs on and off the battle switch relay but that is where i get lost.

i think that the battleswitch is just used as the thing that tells the relay to do what ever it cant switch something on its own i know that much

The battleswitch can switch things on - that's what it does when it activates the relay - but it only handles up to 10A so for the axe motor you need it to switch on a larger relay as in your setup.

Yeah so does the battle switch need its own battery as in my drawing for it to be able to turn on the other relays?

the battlesswitch is jsut a relay and rc interfacae, the rc side will fraw power from the receiver and the relay can get power from the reciver if tis under 5 volts and from the main battery if tis over.

Ah thanks that makes more sense, seeing as those SSR relays only need a 3V control I should just be able to use the power which it draws from the reciever to switch the other relays on and off.

yup

.

If you feel in the mood for a little nerdery, the insides of a servo and a diode will drive that ssr very nicely for free if not for a few quid.

Ok bit of an update could probably do with this being moved to the build or FW section but owell

I now have most the parts for my axe weapon (sprocket chain, hubs, motor and victor 883) still short of an actual axe and an axail. Included a few pictures of the parts.

Next question is about the batteries, I bought 8 packs of these off gravity with the chargers (so 8 battery packs and 4 chargers).

I am going to be running two circuits in my robot one at 14.4 volts and the other at 28.8 volts. So I will be semi-permantly connected the batteries into two twos and one four (I hope that makes sense).

So my question is whats the best way for me to charge these, just do them using the orginal chargers as individual packs or buy a charger (if one exists) that can charge the three assembles packs as whole units?
