For questions about component-level electronic circuits, tools and equipment.
1: Be nice.
2: Be on-topic (eg: Electronic, not electrical).
3: No commercial stuff, buying, selling or valuations.
4: Be safe.
All these BMS seem more designed for high amperage solar system storage, generally using LFP batteries. I'm sure it's possible, but it seems like overkill.
Also Li-ion is not something I would keep in the house, especially a home-built pack. There's a high likelihood of fire. I built myself a battery pack with the same sort of cells, and a few weeks in I happened to walk into the garage when the pack started spewing flames out the side. They can be touchy and definitely need temperature sensors/current control.
Good point and this is exactly what I'm trying to make. I want to start with the battery for emergency power and want to add a home made MPPT solar charger to it.
My battery design involves having a thermal fuse of 65C sandwiched in between parallel cells. I will also periodically check the batteries with a thermal camera to see if any are misbehaving.
