today work --> onewheel XR battery diagnostic

Today I was around onewhell or onehell !

veicule XR symptoms: no nothing!

cause: baterry LiFePO4 16S at zero volts! long time no charge..

test solution #1: inject some controlled charge into pack.
results: OK revive, but maybe only 50% capacity now.. no more radical

check picture.

I have been seeing more and more onewheels out in the wilds around here.
I know Adam Savage rides one, he did a youtube video on modifying one.

Time for a new battery for you.

$450 High Quality Sony VTC6 cells! which are 3Ah 30A 18650.

Or you can build a battery yourself, 54V 6Ah shouldnt be that hard to make, 28 18650's, 14S2P.
$3/cell x 30 = $90 + s/h $40 = $130, get the un-named supplier (but well known on ES) to tab weld each can for an extra $0.25 a cell = $10 so you can solder 10awg solid copper wire from home depot.

This is one of the most danger EV
A lot of bad accidents history for this "onehell"

but some people just like it.. and its ok

It seems recovered battery does no perform good at onewheel..
so I will replace battery with x16 new LiFePO4 A123 cells
