This project looks great. Well done. I would strongly recommend that you install a BMS on those batteries. T JK BMS would be really smart since it can connect to SA and has a two amp balancer also.
I would just use one BMS for all the batteries and just parallel all the balance leads to the one bms. I know this is an older project for you, but I just saw it today.
Cleaning panels make a difference.
The active balancer in the JK puts it in a different league than the others. Also just because something has more settings doesn’t make it better. The JK gives you access to more than you need and simplifies the operation. I researched online for weeks before committing to the JK and now that I’ve been running them for a few years I know that I made the right choice.BYD BMS
A no cut, no splice, plug-n-play. It has a screen, Bluetooth, and more settings in the app than we know what to do with. Will already reviewed this BMS. The Inside wires: The Outside Wires: Conclusion: Molex Micro-Fit 3.0 430251000 10POS 3mm Molex Micro-Fit 3.0 or 1729521001...diysolarforum.com
Oh and the whole “it has a screen “ thing… JK offers a screen too, but honestly you do t need it. For the five minutes every few months you want to peek in on how awesome the JK is managing your battery, the Bluetooth app is perfect. And I mean perfect.The active balancer in the JK puts it in a different league than the others. Also just because something has more settings doesn’t make it better.

The passive balance on these other bms units out there just can’t handle the large diy packs we are building. They are meant for these smaller batteries and evens then they are undersized. The JK can handle a large battery that is out of balance in a few hours compared to the others taking dozens to hundreds of charge cycles to come even close.
