haha cool. more louis rossman related content. recently bought a bunch of old ipad 2 replacement batteries. have never found such a thin fat cell. i think they were 7$ each (for 3 pack, about the same capacity as 18650). good for projects like a 100watt charger+extra laptop usb-c screen based off ipad3 screen and a conversion board. they sell metal shell kits too and everything fits inside if you move some of the surface mount components around on the 100w usb-c board
There is a possibility to fix these. After opening, connect a separate smart balancer to the battery. Charge it up to 35v monitoring the cell goups. Connect the original shimano steps charger. If you get error light 1 and 5 after 30 "led-blinks", it is possible to repair in 90% of the cases. The problem is the smd 30A fuse. Fixed 7 batteries today, just by replacing the fuse. It should be changed while connected to the battery.
Are you sure it is silicone around the temp sensor? I mean, if it is hot glue you could use IPA and it will be a peace of cake to get the temp sensor out ...

Battery wire can be installed at 3 pins with 12 volts
Funny about the Norwegian.... some of us make new battery from old packs and it is possible to bay desent 18650 in norway from 1/2 an Euro pr cell.
Didnt understand what he meant by "split cell groups" and that, I guess, 1.6V cells were good.
And possible can revive it and use it again

Hi Chef
Is the temperature sensor important? And why, because he could not maintain it and unfortunately it broke😢
Wouldnt dielectric grease on the connectors prevent water damage?
Do you have any DT12 smart s working?
I mean smart bms for dt12 phylion
1:05 I see water damage.
