First I tried charging up the battery to 13.32 volts, and tried the pre-charge using a resistor; (graphite pencil was all I had on hand, read 18 ohms), but made no difference. Still showed "short" on the overkill app as the BMS tried to start then switched off immediately. Then I replaced the...

Okay, I just let the SCC do it's job for a few hours and (per my friend's suggestion) restarted the phone and the overkill software. Well the inverter seems to switch on and off just fine, no errors or problems. I am of course happy to be up and running, but a little bewildered. I'll run the...

I don't have a CV/CC supply, just an old school charger for FLA. The battery is receiving solar charge from the SCC as we speak, so I should be able to see if bringing up the voltage helps. Thanks for the suggestion. Also, just connected the inverter to a FLA deep cycle battery (showing 12.5v...

This thread title seemed to fit, so hopefully a good place to start. Just reinstalled my 280Ah LiFePO4 battery after winter storage, reading very close to 13v no load. Everything was still how I left it in October, SCC, B to B charger and 1600w LF inverter all connected to buss bars only. I...

Shore power - just a meh-ah-fore innit? LOL! Okay the motorhomers stole the term!

Yes, good idea!

Looks like a nice tidy setup you have. I was tight for space in my caravan, so much preferred the post mounted fuse; no hot spots either!

Not sure if you saw this previous thread: https://diysolarforum.com/threads/searching-for-mega-fuse-holder-that-bolts-directly-to-battery-terminal.62390/page-2 My home-made mount (solid copper) was cheap, easy and works well. I was able to drill exact size holes needed for each bolt (1/4 and...

Not sure if this suits your particular situation, but I found this arrangement easy enough and cost effective (posted in an earlier thread): I found the Blue Sea less available in Canada and therefore costly when adding US shipping. I bought this MRBF on Amazon.ca...

Okay, just switched to overkill, (which I could not find for iphone last year). It was easy to adjust the start value and is actively balancing now. Maybe it'll do the trick. Thanks for mentioning that Okay, just switched to overkill, (which I could not find for iphone last year). It was...

Yes, have read and re-read many times. Just can't figure out the "cycle count"error. I am not very good with this iphone sstuff!

I just checked; looks like overkill now has an app for iphone. Shall try that rather than wrestle with Xiaoxiang. Thanks

Okay, firstly I need to adjust the "start voltage" on the app. I enter the revised start voltage on the balancer (3420mv) but the app will not let me write the value to the BMS - does not retain it. I don't know how to get by the error message. I did purchase the app for $10 CA (iphone). Last...

Hi all, I seem to have a similar issue on my 280Ah 4S battery. I have gleaned what I can reading the above. The fellow here in Alberta who assembled the battery answered my concern with a suggestion: "Yes that is because of the charge curve of lithium, any imbalance will only show up at the...
