Default Manco Dingo EV Conversion

This will be my first electric kart build/conversion. Iíve been lurking on this site for a while and reading about some of the other membersí builds. This kart will be for my 10yr old twins and 8yr old and weíre going to build it ďtogether.Ē Below are my parts list for the Manco Dingo conversion. I donít care so much about speed as I do about torque and quickness. With that in mind, I have a couple of questions:

1. Will the existing gear ratio be low enough for the referenced motor to be able to spin the wheels in the dirt? The kart is currently stock, so I believe itís got a 51 tooth drive sprocket. The motor has an 11 tooth sprocket, so thatís roughly a 5:1 ratio.
2. What are my options here? Jackshaft? Higher tooth sprocket on axle?
3. Following this same line of thinking, is the #T8F chain 8mm pitch the right chain for the stock drive gear on the Dingo?

Electric Kart Parts List:

Manco Dingo Frame/Drivetrain

Motor/Controller/Throttle:
2000W Watt 48V Volt BLDC electric Brushless GoKart motor BOMA Style w Controller
https://www.ebay.com/itm/164078255744

Batteries:
Mighty Max 2 Pack - 12V 22AH GEL Battery for EW72 Mobility Scooter Wheelchair
https://ebay.us/38muIv

Although, looking at the battery cost for 4, I might just go with Lithium. Something like this:

48V 20Ah Lithium LiFePO4 Battery Pack Fit 48V1000W EBike Motor with Charger BMS https://ebay.us/OKkYZh

But then I wonder if the max discharge amperage on the LiFePO is sufficient.

Iím sure Iíll have a lot more questions and issues as I start this project. Aside from terrible steering performance, are there any other known issues Iíll be facing with the Dingo?

since I just had that discussion a few hours ago..
check the discharge current rating of the battery pack..
and compare it with the maximum current rating (peak, not constant)
of your motor/controller.
I assume something like 55Amps will be needed for your motor..
if that batpack is only good for 50Amps peak you will have to pick a better one

There's a reason the battery is rated for a 1000W motor
(half the power of yours! Very likely it cannot deal with the high discharge without bursting to flames)

I put a 48V 1,800W Boma motor on my Dingo a few years back

It was fun to ride & zipped right along
...but, it couldn't spin them big 'ol wheels

FYI mine had a sprocket for #35 chain
...so, you'll need a matching sprocket for your motor. Their available from Alfa wheels (~$12.00)

Here is a video on changing the sprocket



Here is the build thread, on my Dingo, if your interested (first 20 posts)

Thanks FA. I've been through all of your posts and reviewed a bunch of your clips on youtube. So, I'm thinking I'll see what the largest gear is that I can fit on the axle without rubbing against the guard (not even sure if there's room). I'd be happy with a 15mph top speed on this, but I want the kids to feel the "electric" torque difference, so it may come down to a jackshaft config (although not thrilled with more moving parts).
