Hello All!

I had to replace a fairly dead 200Ah solar battery because I messed up the settings for the battery on my epever MPPT Tracer3210AN.
I have that, a renology 100W 12V panel, and a new Chins LiFePO4 12v 20Ah battery.
I followed the settings in the included manual for the battery, but there were a couple of settings on the Tracer3210AN that I could not find matching values for:
Temperature Compensation Coefficient (mV/C/2v): default value -3 (that's what I have currently)
Equalization Charging Volt (V): 13.80 - that was the highest value I could get based on other parameters
Boost Charging Volt : 13.80 - same as above.
Boost Reconnection Charging Volt :13.00
Boost Duration: 120minutes
Equalization Duration 120 minutes
Discharging Limit Volt: 11.10

I have attached what I got from the manual, and then the settings I hoped to be correct...

But, I am a newbie at solar charging, etc.
Please, let me know if my values are messed up at all.
I don't want to blow another battery!!

Thank You in advance!

James

Thank you, sunshine _eggo!
It’s only been hooked up since Sunday, and it wasn’t too crazy sunny today in Delaware, so I’m hoping I haven’t fried it.
I’ll be heading up to the site tomorrow morning, so I’ll make the changes then.

Thanks!

LFP is pretty hard to fry as the BMS protects it.
