Just to close this out. Ride home tonight after more balancing at the office today.

These puppies are licking the same bowl! 😎🐶👌

Gives a good indication of how the charger works. I was actually watching the cells voltages when the charger flicked to green. They all dropped straight away.

Looks like the balance function was bringing the other cells down to match the low cell. I'd always assumed it would pump power into the low one to bring it up.

I've sourced a 2nd hand battery to have as a backup, pickup this weekend for a few hundred bucks. This scare has been good for me to recognise that this is my daily transport and needs spares to stay reliable.

@Lia the broken tab makes sense based on what we know. Good call.

Rode in again today and got a couple of screenshots post overnight charge. This one is while still on charge. Still holding 63v overall:

Then 30 seconds after turning off the charger, cells stable but overall voltage down

Then after a ride...cells look like they are singing a similar song again.

@biell @Lia thanks, will follow the advice and charge charge charge and monitor.

I suspect it's worse as was not having any issues last week. I have a downhill near the start of my daily, I have to go slow to avoid
a regen trip, I usually watch the voltage on the way down and can hold it at 63.0v. today, after a longer than normal charge and with a green light after the overnight charge. I was at 58v at the top of the hill where usually I'm at 61.7v . Something is different since Friday last week.

the board tripped at 59% remaining with that bad cell at the expected 2.8v after 12km total travelled. Usually I'm up over 24km before it shuts down. Will take the charger to work tomorrow and report back with whatever develops.

Thanks again.

@Enterusername sorry to hear about your crash. Sounds nasty.

How long do you think this pack has before it's done....

This was after an overnight balance charge and a shortish 7km ride.

What is Truly the Difference in say a 35mmX55mmX10mm "Chinese brand" bearing

Quality control. If the job of changing the bearings is easy and if they fail in a big way isn't a concern, then cheap bearings are right for you.

For some applications, changing bearings is a real PITA, so spending more makes sense to limit how often you do it. I'm not in the US, so replacing a motor would take months to source and swap, so I choose to spend more.

Nice, black and white upper middle left....needed my glasses for that one. 🥸

@Lia light blue jeans and a grey hoodie today. Backpack of stuff on board. Did I mention that I rode the 8km home in the rain one time with an umbrella ☔☔. Was slow and got a lot of laughs from all who saw.
