Simpliphi Tear Down? Serviceable?

I have some damaged (weakened capacity) Simpliphi 3.x 48v and wondering if anyone has done or heard of a tear down. Are they prismatic? Its a casualty of over charging and/or over draining them beyond c/2. As Will has said, they are not impressive and I can attest to that. Simpliphi is also not helpful at all. I'm on my own. I would like to turn 9 of them into say 6 or 7 solid 75ah batteries. Is that even realistic? Are all the cells likely weak and just run with them as is?

Curious if you've made any progress with the teardown?

I won't get to it until mid-May. I'm in Hawaii with my new Chinese rack batteries that are working well. I need to ship 2 more Phis to CO before I head back myself in April. I then need to capacity test each of them and possibly find a bad apple in the group. Capacity of the battery group is limited by the weakest one. If they are all similarly weak, then I won't tear into one of them. That said, Phi said that they don't even repair them. That it is not serviceable. All I can surmise is warranty work is simply done by replacement.

Oddly, I hope that one is worse than all the other so I can rip into it!

Example Scenario 1: 2.7 kWh x (all) 9 = 24.3 kWh 2.9 kWh x (one less) 8 = 23.2 kWh. Result: Keep them all
Example Scenario 2: 2.5 kWh x (all) 9 = 22.5 kWh 2.9 kWh x (one less) 8 = 23.2 kWh. Result: Ditch the 2.5 kWh "bad egg"

Makes sense, replacement seems to be the way of the world, despite what could be repaired.

Looking forward to seeing what you find!

We have 26 ( thats right some $70k of battery) of these "marvelous" batteries on our warehouse floor. Its no wonder they sold out to Briggs and Stratton.
The problem with these multiple cell batteries there are too many cats in the bag; with no way to heard them ( control and service) . The BMS unit seems to fail. Ive decapitated a few of them and attempting to change out the BMS. Accessible large volume AH LifePo4 are much easier to use and service. We intend on replacing the Simpliphi "proprietary" BMS with something like an Overkill or DALY BMS
