I recently picked up a meepo 40T 10s2p from another forum member here. I bought it as an upgrade for the 18650 20R 10s2p I was using before.
I am using a backfire enclosure and it doesn’t really fit (I have to use a big spacer), so I think I will need to take apart the battery and lie the cells in a different configuration to help it fit in the enclosure (I need to go from the cells being directly stacked on top of each other to having them in diagonal, like this picture)
I am also going to take this opportunity to bypass the meepo BMS and add more nickel stripping since I head that it’s pretty poor from factory.
One thing I think I would like to do is scrap the meepo BMS and add a couple more cells to make this a 12s2p pack. Backfire has a 20700 12s enclosure that would work perfectly for this and my cells in my pack have < 3 cycles on them.
Is this a poor idea? I figure since my cells have little use it will be safe to balance charge them all to match two new cells then add them in series.
