I'm Here, But I'm Not All There
Background:
While I wait for my LFP bank to arrive (just ordered so I expect 60-90 days) I am wondering about the importance of Capacity Testing and Do I REALLY NEED to purchase more equipment than what I already have. The bank will be an 8s2p, two BMS set up with 272ah cells totaling 544ah.
I currently have a Conext SW 4024 Inverter/Charger, Connected to LA batteries. Also have a MidNite Solar Classic 150 with the Whiz Bang Jr. The whole set up is tied together thru a Midnite solar load panel with a Shunt installed. I can right now see how may AHs I put in and take out of my LA batteries. The only issue may be that this can only be reset (as far as I know) when the batteries reach 100% SOC as determined by the Classic CC settings.
I figure once my LFP bank is Top Balance etc and set up. I could possibly load / capacity test the new LFP bank using my inverter and a big load (like 80amps) with my SW. And if I turn off the incoming Solar Array for the test, I could read the AHs removed via the network app Classic Monitor and/or the Midnite solar LAN PC app
Question:
So if I have all of this already, is it really necessary to purchase say a cheap 150w 200v 20a (or whatever) capacity tester or will what I have do the same thing and probably much faster because I can apply more load. Do I already have what I need to reliable do a capacity test?
