Battery Monitors
I've nearly completed my upgrade to my Solar System(Pics coming when I'm done). Thinking(after the fact of course)that I should have considered a Battery Monitor in the upgrade, or at least preparatio...

I have 200ah lifepo4 battery bank and pd 35 amp charger/converter and Trimetric meter.
Here's what Bogart Mfg said about the Trimetric:
We have a link below to the TM-2025's User Manual. In it you'll find, on pages 6 & 7, a description of all the 'P' parameters.
For Lithium LFP batteries, the changes needed are as follows:
P1 - 14.4 Volts.
P2 - 2% of P3 (battery bank capacity)
P3 - Battery Bank capacity in Amp-hrs
P7 - L3
P10 - 98%
P14 - 0.00 hrs

Progressive Dynamics said to use the boost button to fully charge the battery.
I am not using the RV now due to health issues, haven't since July. I've had the rv on shore power for 5 weeks now without pushing in the boost button as lifeo4 are best stored at 50-60% soc or so. My meter says SOC = 72% and it's not being charged, just maintained. It has gotten below freezing at night & the BMS is supposed to shut off the charging then. I hope this is working well. I could limp out and spend time unhooking from shore power & removing the batteries to bring inside. But if what I have now is OK I may leave it that way. Not sure though.
