Depending on what motor it is, it’s probably similar to this
Disassembly is the inverse of assembly.

Torque 6 esc has a 5 amp higher cont. Current rating and 5mm bullet connecters compared to the stormcore. Gonna squeeze a bit more amps.

My buddy at a machine shop had 6 of these cnc aluminum spacers for a shower curtain, they work perfectly for spacers for the boardnamics gear drive to avoid cutting motor shafts. I was considering popping a bearing in the spacer to help shaft side loads.

I have 4 3s6p packs. The first time i charged the batteries the were all spot welded without the series break and they all charged to max voltage 4.2.
I dissasembled the pack because the series connections were not sufficient for higher currents. I doubled the nickle between each 3s pack series connection and used appropriate wire for the break in the series.
Each new 3s 6p pack has a main negative, and ascending cell voltages in relation the to the mt30s.
I can plug the pack into the bms by first connecting the batteries in series, connecting the main negative, then connecting the packs by ascending order.
The battery seems healthy. The cells were new but old but also charged right up the first time. I was short for time and rode around on a partial charge and the 12s6p did not sag or drop much voltage so it seems to be as it should.
This is the second bms i have installed, but for whatever reason the packs will not charge fully anymore. I do not notice variance in the p groups indicating anything funky with cells and i checked my welds they are on there.
My question is does the lenth of the series connection matter for a charge bms? The pack charges to 48v and then my charger blinks red/green. The polarity is right, and its not my charger.
Fwiw i can use the pack without hiccup it just wont charge * i dont use this pack but simply tested at partial charge without hiccup.
How can i check for a bad cell without charging 72 individual 18650’s? As mentioned the p groups are without variance or diminishing voltage.
Also wondering if i should have discharge hooked up to keep balance in the cells, currently i have it bypassed due to current restraint on the bms.
Do i loose regen balance braking without discharge hooked up?

Welds look fine to me, they are on there
BUT, i did just discover my bms main negative was not connect. You win, im a fool:weary:
. So odd how this went through without me noticing. I feel certain that is the issue.
Has any harm been done?
We have charge!
Charger stopping at 49v ughhhh y??
Wire guage from bms to batt V important. Upped the gauge and the battery made it past 49v

So i added a e brake line to the mini bike, you pull the lever and it clamps the disk.
I cannot get enough friction between the aluminum disk and the rubber pad. Ive tried many materials and adjusting the lever but it cant get me to stop. Anyone have suggestion for stopping this tank?

If you don’t have access to the other side of the disc, a drum brake might be your best option tbh. If you can space the disc off the wheel, set up a screw mechanism like other mechanical disc brakes

Let me take a look into that, thanks for the suggestion.
Awesome idea!
Rigged up a drum brake from a scooter. Just had to make a brake pad and straighten the clamp. The results are significantly better. Thanks for the suggestion.

Thanks man! Wait till you see it finished lmao. I think gear ratio of 1:5.14, then 18/42 for some serious torque. Total 1:11.99. It weighs a bit we will see how she moves.

How will the extended swingarm/steep head tube combo ride?
it seems okay. Top speed is 17mph. Its comforable to sit and turn but i took it down the drive way to test the brakes and it hardly felt natural while moving. Ill have to play around with the handle bar positioning. Can you clarify why this is a problem persay… like what is a more typical way to orient the bars?
Also the seat is in a good position relative to the swing arm in the back but the tube angle is defiently steep
So, the length of the tail affects the turn radius you get, extending it makes things more mellow. Raking out the fork (as in pointing it forwards like a chopper harley, not talking about the bars) makes the front track more steadily.
It’s conventional to have a short rear and a slack front, but you have the total opposite. I’m wondering if it cancels out and the bike still feels good to transition.

I see. It needs power to get a proper feel i have the chain on now and cant test it down the drive way.
Maybe a bigger front tire?
