Discrete Large Lithium Battery Control
This gets a bit involved so grab a cup of coffee. There are dime size discs that have been around for decades that shut off AC power when a certain temperature has been reached. Most are guaranteed...

Yes I do a static and a dynamic cell per cell voltage test. And a home built 200 amp 50 pound transformer that peaks 3.9 voc. Thanks to Lockheed advanced projects.
What I propose is most useful on single series string 3.7 volt cells.
Take a 100 amp hour battery and charge it at 50 amperes, and throttle the current by limiting the voltage. If lithium HAD to be current regulated meaning constant current charged it would be a first for me to see it. 250 watt Meanwell power supplies are cheap. And they adjust down to 3.15 volts. So are the temperature cutout switches inexpensive.
Three N/C temperature cutour switches rated to 45c.
Three 5 digit panel volt meters.
I can build one of these gizmos for around $200 to $275 NOT INCLUDING THE ENCLOSURE.
And from what you are describing (inadequate control and monitoring) only a PC based A to D to A data acquisition board to PC interface would be superior.
The BORG was supposed to be "impossible". I hear it chuckling at me next to the bed after 7 years 24/7/365. Or is there some other 100+ amp charger out there that operate with the smallest generator sold? All it takes is experience designing this stuff then some classroom time learning the in's and out's.
Engineers have an advantage over DIY
And one Intermatic 4 hour wind up timer.
