Where did you get 200+ amps goal?

Have you seen the one where he steals his own brass tapware to melt down :rofl::rofl::rofl:

Nope I haven’t I think I have seen like 4 videos of his.

Sounds like a huge leap forward. And 225A for a 105 pound rider… that’s probably more power than you can use anywhere but on a track.
I would recommend taking it easy and get 2x80A motors and a 120-160A capable battery.

Just my $0.02

Edit: realized that I over read that you will race it.
In that case, I would recommend to loook deeper into battery amps vs motor amps.
Your current motor selection is not a good match for a 225A battery.

A rough half correct example: if your battery can push 100A, and your motor can handle 200A (as in VESC settings), then your motor will be the limiting factor until you reach approx half of your top speed.

I’m sorry but what do you mean by this?

Thanks! I’ll look into that a litttle deeper!

Fark, I just realised that is one thread that got seriously shafted when Deckoz bailed on us :unamused:

:disappointed_relieved: Rip…

Yes but an XT90 off the battery won’t work. You need something 200A capable. That’s why I recommended two batteries over one.

Oh are you sure he means 225a per battery I think he means overall @DEEIF

Also good stuff in here @DEEIF

Ah my apologies. For a race setup I’d consider the opposite. But you’re gonna need copper bus bars on the whole system. The battery will be pricey and heavy. Output to dual 8awg off the bus bar to xt90s. 10awg to the ESCs. Keep a minimum number of connectors and the cables as short as possible. A single config will be slightly lighter I think. And a dual battery setup will reduce your # of P packs per side which might increase your voltage sag

It’s gonna be pricey. And you’re operating at extremes so plan to need to tackle heat

I don’t see the value in dual batteries, you can just run multiple terminals from the one battery to the same effect no?

Yea but with small cells you can have a fairly small surface area to mount those two without getting hot points. A good builder can do it fine with the right components

Just use 4x 6396 (not 6369) each with its own 12s2p battery and some version of a VESC 6…all the power and none of the connector melting current

I meant overall amperage of the pack for anyone wondering😁

Thanks for the link @glyphiks

Saaaaaaaaaagggggg

One single pack will always be better (more effective and efficient) than multiple packs if the same amount of cells are used. There is simple maths behind it but I’m drunk and going to bed. No more multiple pack speak please.

There’s a big difference between peak draw amps and continuous. At your weight you won’t pull those amps especially not with those motors. Also the higher the voltage the lower the amps.

If it was continuous with you described battery. You would get 5 minute runtime and 4.6 mile range (if you were going 50mph, someone correct my math if I got that wrong)

Can he withstand the amps/force of the board? Just asking.
