life my way
I used the Watchpower software this morning to set the CC to Bulk 29 and Float 24. It didn't charge. By the end of the day it gave me Fault #4 Battery Voltage Too Low. It was like 25. I shut the battery breaker off to shut it down.These packs won't balance until you hit the balancing voltage threshold. So be sure to charge your BYD packs to 29 volts(3.625V for each cell). And cycle down to 23-24V. Repeat this over and over.
If you want to cycle up to 90% SOC, use a shunt and set absorption manually. Thats the best method. Dont set absorption manually till you cycle it a few times.
Yesterday I tried the 26.4/24.4 range. Nothing.
Day before 27.4/25.6 range. Nothing.
I will post a picture of all my settings tomorrow. Maybe I have something totally unrelated to Bulk/Float settings that is messing everything up.
I will also connect to different LV2424s, I have 3 of them. Maybe the one I've been using is busted. I don't think so, but it's worth a try as troubleshooting goes. I won't change any of the stock settings right away just to see.
Something is wrong. They don't charge. How can J possibly test their capacity, or even play with charge settings if they never charge in the first place?
