Thanks all for the input. Yes, The battery is "topped up" first thing in the morning, as the sun comes up, (takes about an hour) Overnight Low voltage is 13.22V Then it goes into Float all day. No loads on the system, as Van is only used rarely at weekends..

I have a new 12v Bank in my RV, made from 4 BLS 190Ah cells, and 2 x Renogy 160W Panels, running through a Victron 100/30 charge controller. I have absorption voltage set to 14.2V and Float set to 13.6.. I am seeing the voltage raise to the proper 14.2, first thing in the morning, and then...

Yep.. seems silly to turn it off, so I've set it to 1 degree lower than the Victron level. Again, thanks for the link, it saved me buying a new BMS..

@Sgt Raven .. Thank you so much for the link to the new software.... Works a treat. I'll ask @Will Prowse to replace the old version he has on his site, as this is so ooooo much better... I was going to replace the BMS because of the software, and the fact that I no longer require the low...

Does anyone have a later version of the software for android, I am using the one, Will has on his site. Its the enterprise version, so changes can be made. I found the one in the play store, but that is extremely limited, and does not allow any changes..

So, choosing the "about Xiaoxiang" only takes me to the Bluetooth settings, and there is no info annoy the app there. Looking at the info for the app icon, it looks like version is 2.0.1006. My parameter view, shows lots of info, but does not allow any changes. This has to be done in...

So I have this BMS (the 100A version) all hooked up and running nicely. Apart from the fact that the single cell full limit is set at 3.4V I cannot find anywhere to change it in the settings page. My Cells are the 190Ah Blue cells from BLS, Bluetooth is working well, I can change a whole...

Does anyone hav e settings used and examples for Android?... I've go the App from Will's site, so am able to change the settings..

As with all things Solar..... It Depends... Higher voltage panels will hurt the battery. Imagine shoving up to 100v straight into your battery?. series connected panels will cause problems. Best to avoid doing this I believe..

you should be wary of alternator charging, especially as you have 2 LIFPO4 batteries. Normal Alternators do not cope well with the demands, and Marine altenators could be fitted to a van, but cost!

I like the choice of Victron stuff.. For the low Temp Disconnect, they do a small magic box, which connects to the 100/30 via Bluetooth, and provides the charger, with the temp, so it can stop the charging at the temp you specify...

I got the 100A one which Will liked, from BatteryHookup in the US..

Yep, Bought the 190Ah cells before Xmas, they took a whie because of the shutdown, but when they arrived, they were good, new , grade A cells, which capacity tested just above their advertised capacity.. I have them built into a 12v system, waiting to go into my Motorhome.....

Not the most exciting idea, but useful.... A redo of the most complete build video As things have moved on. Using the octocoupler, etc....

I'm in Wiltshire.. I was getting stuff from ebay from China, but delivert times became ridiculous, so Amazon and UK only Ebayers are now my go-to...

Thanks Steve. Downloaded that now...

No Manuals here either.... a quick vid would be nice!

I ordered these same cells from BLS in Dec, They arrived about 2 months later... They have a QC sticker, and a Barcode in a little window next to the nice clean terminals.... I'm just charging them up, and I'll do a capacity test...

Anyone got an easy, English version, of what the settings are about, or at least which ones we should change for a12v battery?

Will. Would you be able to do a list of all the settings for the Xiaoxiang software which you have on your website, for a Battery made from 4 of the 195Ah Cells on AliExpress?. Finally got all the parts together, and started putting it together, and WOW... thats a LOT of stuff in the...

Huh.. thats odd... The item I bought was the MPPT 100/30, so they do solar chargers, just none showing on the site.. perhaps a site update happening?.

I just wanted to let any UK based members know that https://www.ukenergyhub.co.uk/ are a good bunch of guys to purchase Victron stuff from.. UPS lost my parcel, but these guys instantly offered a replacement, or to re-order, with no hassle, and then a discount on my next order... Even...

THEY ARRIVED!!!!!.. Originally ordered on 14th December, and had the dispatch date moved about 4 times...... They look nice and new, clean terminals and all have the Little Quickview Barcode.. The Bus Bars are a little dissapointing .. they are 3 really thin bars, just heatshrink...

Does anyone know if Daly ever fixed the Low Temp cutoff on their BMS that Will tested, and had fail?

Well.... I'm not sure if I should be pleased or Pi**ed.. My order of these https://www.aliexpress.com/item/33035453389.html?spm=a2g0o.store_home.productList_52597319.pic_0 had 3 delayed dispatch dates.. the last change said it would be another 19 days till they were even sent out.. I...

I ordered in Mid Dec. the time to dispatch has counted down to 1 or 2 days a couple of times, due to the Chinese new year, and Coronovirus. A few days ago, it went back up to 19 days before dispatch. But then this afternoon, I got a mail, showing a tracking number and it's on it's way with...

Heads Up... Anyone waiting for delayed deliveries from AliExpress, check your orders.. Mine just went from 19 days, (only changed to this a couple of days ago), to dispatched......

Looking at buying a new Solar charge controller, and the SmartSolar 100/30 looks like it's got better Wire Connectors than they used to have, that Will said he hated!!.. See the new version Here...

My Ali order of 4 190Ah cells, has just had the delivery time extended for the third time. Originally ordered on 14 Dec, I'm now told that the delivery will start in 19 days.............. I'm not holding my breath.....

My countdown was down to 7 days, but got reset today, to 17 days before dispatch..... Who the hell closes for 3 weeks for new year?

I have just bought 4 x 195Ah cells from AliExpress. So I'll put Wills 100A BMS with Low Temp cutoff for a 12v Battery... I don't yet have any Solar on the Motorhome, so I will need a Mains Charger for when I'm on shore power.. I like Victron equipment, but I'm confused about which charger...

The Ad states these are New Cells......... Going to be a problem if I get used ones..............

How refreshing...... A Grown up attitude to a forum...... Well Done Will and Mods!!
