@Ottohoff what is the new charger? What are its specifications?

There is a bit of tech in the charger to control the charge rate during the charge cycle that you will lose by using a generic charger.

@jackiemoon I use the onewave app which is available on GitHub. It will talk to XR's not sure about pints and give individual cell voltages so you can confirm if it's a balance problem.

@NotSure it's true, @Lia's last name is Stark.

@Lia said in Reviving a destroyed Pint:

@stinkyface PLA currently still, was considering PETG for the final one but will see if I can get away with PLA at a higher wall thickness and infill density. I'm not sure what sort of heat the ESC is going to put out...

Yeah the only data points we have are the generic "controller temp", I've seen mine at about 45 deg C here in the tropics, it's getting pretty close to PLA softening temp. PETG only gives a bit more room. FWIW, I'd do what you are planning, trial and error is a slow but effective way to evolve a design.

@Lia what material have you printed with? Any concerns with temps on or around the heatsink?

@Alexmcc take a look on the diagnostic section in the app and see what the actual voltage of the pack is. Fully charge should be close to 63v, flat is about 44v.

The percentage data is an approximation that the app uses and is known to be inaccurate, particularly if you don't balance charge the board very often. 90% is at the extreme though.

@bgood420 it's not clear cut if the board deactivated due to both sensors not detecting or deactivated due to the BMS shutting off power. The sensor alarm may have occurred minutes before the nosedive.

@Kielanders seconded. To import a new board or get a board returned into Australia after repair, you need to pay a fee to declare that it isn't a motor vehicle!

@RickN I'm not sure. I'm in Australia, so time zones may come into it.

All I know is I rode 15km on Sunday before midday, then 7km this Monday morning. My week count says I've ridden 11km this week??? Which makes me think it kicked over into this week part way through my Sunday morning ride.

The cutover time would be somewhere 0hrs UTC/GMT.

Anyone else got any data to assist?
