@ikaruspint Yes, the 2n7002ps-115 are the correct mosfets.

Baby snapping turtle. I got it off the road once I saw it.

Update: I'm pretty sure it's doomed. I'm not sure I can fix that. Let me know if you still think it's salvageable. Not really sure what would have caused it. This is what it looks like under the balance connector.

@cw_o Welcome :)

If the price is okay I'd take the risk. Getting actual chips from companies like Mouser, Digikey and LCSC can be pricey once you get to the shipping screen. I've gotten chips from eBay and AliExpress (likely the same source) without many issues for things like IMUs, Mosfets and a handful of logic ICs.
Get multiple though just in case you need to redo it. No more than 5 should be fine. IMU's are fragile so you may need to try a few times.

@lia Update: It is indeed NOT fixed. After 2 half charges, the symptoms returned. I have noticed that it happens when going uphill. Going to do some testing on the BMS and see if I can track down any faulty parts.

@cw_o You can try NRF or DigTilt to recalibrate the imu, have the board level when recalibrating.

@lia Tire is good, but I'm only a couple rides in. I've been trying out different ride modes, so not sure what's the tire and what's the mode/settings, LOL. I have not noticed any real edge when carving, so that's good. Size increase might also be a factor in why the bumps feel smaller.

@lia I saw it, can confirm was awesome 😊

@lia thanks! Gives me something to shoot for swapping and seeing if I can throw together another board!

I also think D21 next to c68 looks a little swollen. So probably gonna swap that too while I'm at it.

@lemur i wish it was that but i tested all of the main harness wires with a multimeter and everything seems to be in order. Also i tested the balance connector’s pins with a multimeter and it appears to have a short through multiple pins.

@ikaruspint It should be no problem pairing.

@aiden1983 At this point I cannot give you any good advice, just guessing.
Just be aware throwing parts at it may not be cost effective and may cause a massive short that can cause a fire, ask me how I know.
I always plug in the battery outside after a repair.
Maybe look for a working Pint controller circuit board instead. Sorry.

@compo Hi! I have the same issue. Same noise. No charging, no powering on. Dead. Have you had any luck repairing?
Only 600 miles on this Pint X. Already replaced control module 120 miles ago. So disappointing. Getting frustrated with this thing.

My onewheel plus started showing 4.2 at full charge instead of 3.6 for the lifepo on only one cell. This gave me some reassurance that the BMS is just false reporting after a certain voltage because i notice it does fine all the way till around 3.6 than cell group 1 just skyrockets to the high 4s which would most likely have exploded the battery several times over if it were true as ive only just noticed and have been charging it to 58.4v for years. Im not as skilled as you so im just gonna leave it as is, overcharge warning has only shut the board off on me one time and never while riding, only when i came to a full stop after running downhill. Thanks for the write up!
