Hello again.
This time I have a different question all together.
It's about battery packs and the posibility to change the BMS from what was delivered with the pack, to a different one.
I had a small accident when soldering a BMS. While desoldering a couple of bigger cables my soldering iron made the solder form beads as soom as it melted and two of those beads rolled down the PCB and onto the table. At least i thought they did. And to begin with I saw only one bead. And yes, my soldering iron sucks. Even if it is brand new. But that's what we have to finght with here in this forsaken country.
So I checked the PCB for any solder beads on the run before I closed it and couldn't find any.
Connected the power, switched on and the smoke came out..
Turned out that a bead has lodged it self under some cooling ribs that was impossible to see without removng the ribs them selves.
So, I ordered a new BMS.
Of course, it takes a few weeks for it to arrive, but this time the screwed up norwegian mail had done it again. They had actually returned the BMS to sender from the area postoffice without it ever coming close to me being able to pick it up at the local post office.
Theese guys p....es me off somethng royally. Norways best at..... Incompetance... Jeez.
So, I had to reorder and I now have to wait for at least three more weeks.
So, I was thinking. Isn't it a easier and better sollution to this?
I know many people are making their own battery packs, so I wonder. Could I buy another BMS, fitting a 52v 20ah battery, and replace the one originally in the pack?
If so, what kind of BMS would you recomend?
And also, since I use two batteries in parallel, should it be the same BMS in both batteries to make sure they stay as equal as possible when it comes to charging and power use?
