I have been using the Bogart SC-2030 and TM-2030 units for a several years with a pair of Battle born GC2 100 Ah LiFePO4 batteries in parallel.
I may have been one of the earliest to replace AGM with LiFePO4 using their solar charge controllers. It took a while working with Bogart Engineering to arrive at parameters that worked well. I replaced a Zamp Solar 15 amp charge controller as I added a 160 watt panel on the roof plus a 120 watt portable panel which exceeded 15 amps.
Using a true LiFePO4 MPPT charge controller would have been easier but the Bogart was less than a year old and I was not prepared to throw away the investment for questionable gain.
My only regret is that I had not won the lottery and could more easily win the argument with my wife for the expense. I had my eye on some more ham gear.

I thought getting old would take longer.
