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 Maybe the app is out of date?

I binned it in the end. I suspect it had a faulty / loose connection internally. If yours is firing back up by itself it's likely hitting, or thinks it's hitting one of the safety cut offs. Jimmy

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...

https://a.aliexpress.com/_mLpoP1p The specifications look very good. 200a continuous discharge 350a peak discharge 2a active balance Adjustable via Android App Has anyone used one? Jimmy

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

Which metal box did you buy? Jimmy

I don't work there. The OP contained a link to the website with the contact details... Jimmy

Any updates here? I am looking to pull the trigger on Batrium too. Quality BMS is worth the $ in my opinion. I have a Cerbo GX on order too. Can they talk to each other? Jimmy

The Overkill BMS are JBD BMS see attached photo. Wouldn't you just go a native 16s over mucking around with two 8s??

I am glad you asked Alkaline as I am looking at the same thing at the moment. I am building 3x 16s battery banks for my own use and plan to run them in parallel with separate BMS for maximum redundancy. I am considering: ANT, JBD, DALY and Chargery I have JBD and DALY here in use at the...

Mate it's been a bloody mess. Their shipping agent delivered the goods to a randoms house in regional Victoria! It sat there for 4 weeks. The resident finally tracked down the supplier and told them about it and it finally made it back to me in Brisbane! They were pretty beat up. The 12v one is...

Hi, I am looking at these cells but cannot verify they are what I am being told they are. Can anyone interpret the numbers on these cells? Thanks in Advance! Jimmy

They still haven't arrived! They are due tomorrow or Monday. Jimmy

I ordered some in mid Feb. It took them over 2 months to send them and then they sent them to a completely wrong address in Victoria. (I am in Queensland) Their shipping agent cant sort it out, so I am dealing with the resident at the wrong address, who has thankfully been very helpful. I wont...

If anyone in Australia is interested in a group buy let me know. I am looking at 100+ for my own needs so shipping will be pretty cheap to add some extra on. Regards Jimmy

LifePo4 prismatics in 16s Jimmy

While the Covid-19 lockdown here in Queensland has delayed the PV install it gives me a bit more time to finalise the build specs on the rest of the system. I am fairly happy with the rest of the setup but am still deciding on the BMS I am going to use for the battery pack. It needs: - 16s -...

Link died a while ago sorry. Sold out

www.wish.com/share/2292kbbfqx This looks like the one Will tested which I use for the last 3 months now. Not 100% though. But at $23 AUD hard to go past. Jimmy.

I have ordered some samples to test so I will know in a few weeks.

Hi All, There are a number of solutions on the market now in this space. These units are of interest to me for larger systems that can really benefit from the higher PV input voltages as far as reduced wiring over distance goes. If you have any others worth considering please add them. Has...

Yes. Sea. Port of Brisbane. I have to arrange clearance my end.

I have been quoted $299 for 50pc to Brisbane. Seems reasonable to me for 275kg. There is clearance to pay this end too though. Jimmy

For those of us yet to play with these things what is the go?

They had: Marked terminals Barcode/Serial # scratched off 1 cell was mismatched ~10% Otherwise good cells and great value. They were easy to deal with and sent them superfast in good packaging. But misrepresenting a product like that is a showstopper for me. Jimmy

I have been speaking to them for a while about supply levels and nailing down a few specifications on their 48v packs but have not ordered anything yet. Lucy Xu has been good to deal with and I will definately be ordering something from them in the near future.
