Great job. I've tried recelling these power tool battery packs and they are very difficult. I didn't have a solder sucker. Only the solder wick and like you said really heated up the board too much. Very difficult to get that pc board off in good working order.
Indeed they are a pain - I wouldn't likely do it for a customer, but as this was my own, I'm pleased that it all worked out OK - working fantastically, still!
Re your solder sucker: You'll probably find that the knurled part of the barrel will unscrew from the unknurled part. Plus put a bit of grease/Vaseline on the inside of the barrel, you'll be surprised how much extra solder sucking power this will give you.
This is a really cool video- I love seeing these types of repairs. I’m just curious though- do your rings ever cause you problems? I would think for someone who works on batteries, it may be a pain in the ass the worry about them. Not judging. Just learning and curious. I’d like to get into battery repair at some point.
Great video! Thanks! A small question: by recelling you didn't use the same kind of cells. What criteria do you use to choose the cells? their maH muss be the same?
@@EbikeRepairsI haven’t watched the full video yet, but how do you know the BMS can handle the extra power? I mean, worst case scenario you just get the same amount of power as before and there’s a bit of wasted potential (no biggie), but were you able to verify?
There's no extra power involved, just more runtime 👍 after using it, it will mow my front and back garden and verge on one charge, so it definitely did work. But sometimes packs use coulomb counting and won't let you use larger capacity cells, however this one is definitely not advanced enough for that, BOSCH Ebike BMS's use that and they're much more complex 👍
Love you watching you rebuild battery
Thankyou!! :)
nice to see you do more than diagnostics
Thanks 👍

If you put flux on the wick, it helps suck the solder away much better.
Oooh thankyou! I'll try it next time :)
love the videos ,nice one
Thanks 👍

thankyou I shall give this a try👍

They don't, they're ceramic! :) metal rings are a big no no when working on batteries, though

I used better cells - high discharge rate as they are only in 1p configuration, and slightly higher MAH rating for a little longer run time. 👍
