Does anyone know the trick to resetting the AH Capacity in some DALY BMS? Half of mine work fine. Some are fine to 50ah then if you set it higher revert to 33.5ah and other odd figures...

Have you tried charging it up to full and setting the SOC to 100%?

If your using a two wire start system the generator starts when the two wires are shorted together. As such you want to use the Common and NO ports on Relay 1. (The generator controls only work on relay 1 on the Cerbo) NO is the normally open relay contact. As in the circuit is broken until...

Mine runs to a digital controller on the generator so it's only a tiny current. Mine is ~5m run but I would not expect any issues with a 15m or even a 50m run. Jimmy

Hi Fraser, I have one running the auto start on my property off grid backup generator. You need to have a 'two wire' auto start system on your generator to use the Cerbo GX generator relay. Its just a NO relay that closes on command and shorts the wires. The Cerbo GX comes with some press in...

Champion! Thanks

I gave up using this after my last post in 2019. I went to load it up and now it won't even connect anymore. Maybe the app is out of date?

Their response was that the manufacturer just does that with the codes. ? That being said those cells have been cycled hard for a year now and I have learnt alot about Lifepo4 so all in all not a bad outcome. Jimmy

Hi All, What is everyone using on their larger battery banks? I am building some 15kwh 48v packs for my off grid system with 150a BMS so looking for a 200a fuse / breaker on each bank. There is NH1 style Fuse Disconnects on the current LA battery setup. Are these still the best way or...

Thanks DZL

With all due respect, I am interested in the experience of someone who has used one. FYI Overkill Solar BMS are rebranded JBD BMS which are some of the cheapest on the market. Don't get me wrong I am not knocking Overkill (I have never dealt with them) or JBD BMS (I run a number of them and...

He sells new Eve and Sinopoly and a bunch of other brands of second hand cells.
