My Space Cell is dying fast and I need to check every cell or even each of the series packs is fine. Its progressively getting worse by the day. Either the cells are just dying for whatever reason or the BMS is failing, in turn not charging the cells properly.
If I can salvage some cells, I’ll probably just build a new one, but if using old cells with new ones is not a good idea, I’ll just buy a full set. Speaking of buying cells, when is the next group buy for some 18650s?
you could have one dud within a bunch in parallel holding your pack down and you’d never know. if it’s soldered together you’d have to unsolder it to find it.
I was initially reluctant to send it out to someone, because I don’t have a spare battery, but I have no other choice. I’ll have to find another one before I send it out.
That’s what I thought too, but if I took the cells apart (they’re welded) I wouldn’t be able to put it back together since I don’t have a spot welder. Plus, I was afraid of shorting when cutting the nickel tabs.
I remember charging it and actually using it for a little bit, then the motor went bad. I initially thought it was the VESC so I ordered a new one and had to wait around a month for it.
For a while after getting the new VESC and motor, the Space Cell was working as it should have, but I think, maybe the reason it went bad is shock from the road and bad sidewalks with broken cracks, because the enclosure ended up breaking at two of the mounting points as my board has kind of a big concavity to it.
Yep, bara is legit - he revived a pack for me. He works fast, his work is clean, he uses high quality components in his repairs and he answered a bunch of my questions (battery assembly turns out to be a lot more complicated than I thought).
