That's what I've done in the camper, every time I turn ON the main switch, I just press the button first. I see the inverter lights light up, so works like a charm.

I ordered 8 cells (VariCore 280Ah), from the link in the video description by @Will Prowse - when they arrived I checked the cells. Some were not flat, others were not. I started testing, see the topic here. I never got close to 280Ah, even though there's a big white label on the cells saying...

First response was 'do a capacity test', which I did, else I wouldn't have noticed the lack of capacity ;) I'm currently in dispute, AliExpress stepped in, posted test result, they wanted a movie, etc. Current status: they offered a near 300 Euro refund. But then I discovered that they...

Yay, t-class fuse arrived, but the fuse-holder is so large, had to switch places, so ended up on top, while still being able to access the cell terminals. Didn't have a cover, so ended up 3d-printing one. Put the BMS on the front. Only thing I missed, was that the bar with battery main...

Finally able to use my JK, 8S, 2A balancing. Figured I had to assemble the 24V battery first, for a quick charge before I did the top balance. But assembled it, charge it slowly using a 10A power supply and when there was a cell over-voltage, let it rest for a while, charge slower, did that a...

Not only 'crap', but in this case, plain old fraud: relabeling 220Ah cells to 280Ah isn't even B-grade, it's just fraud.

Righto, I forgot to use the conductive paste on the BMS connections and fuse and so on, only used it on the cell terminals. So, took the thing apart, re-routed balance cables and made a protective cover for the BMS. I'm done ;)

I've used 'carbon conductive paste' on several connections related to the battery. As per spec: https://mgchemicals.com/products/grease-for-electronics/electrically-conductive-grease/conductive-paste/ But I still would like to use a tinned connection instead of bare copper. ;)

Besides end plates, there would be a bottom plate, the rubber mounts would be screwed into that plate and then the bottom of the camper box. So the cells would be clamped, the bottom plate would attach the battery as a whole to the floor, but still lessen vibration.

FYI, I had a shipment from Amy come in and take over 3 months to arrive in The Netherlands, Europe.

Actually, turns out these are 220Ah cells, resleeved as 280Ah. See images in https://diysolarforum.com/threads/cell-imbalance-during-slow-capacity-test-not-even-near-rated-capacity.26361/post-323233

If you're using Victron Lynx, they added a T-Class fuse holder-with-busbars to their product line. https://www.victronenergy.com/dc-distribution-systems/lynx-class-t-power-in

Personally, I wouldn't use a Class-T for each inverter, but for each battery. I'm currently preparing to build a Victron based 3-phase system, that's 3 linked inverters. Of course, the inverters will be fused, but not with Class-T.

I would certainly dispute with Ali. But they require a lot of evidence - I've done several tests, created time shift videos (also see this thread), taken photo's. In addition to testing and disputing, peel back the black covers on the minus terminal. Mine had scratched QR codes but beneath...

Hello J, Thank you for your suggestions. I don't think I can use a metal enclosure, but could use special flame retardant panels on the inside of the electrical compartment (under a seat/bed). There will be a fire alarm in there. However, now that I think of it, because of several appliances...

Yes, using tinned lugs, with conductive paste. I think I'll remove the 2nd nut, as it only hangs in but a thread :sneaky: and then put the balance lead ring terminals on top of the main lug instead, and will use nylon locking nuts instead of the supplied flange nuts. As far as I can see, the...

Bob, thanks. I figured as much but had to make sure ;)

The balance wires are tiny, I believe 22AWG.

But there's a huge difference between 'bloat' and 'not flat', right? (edit) Ah, answered. :)

What about swapping the positive and negative terminal around, so the fuse is not anywhere near the negative?

"send them back", I think the shipping cost back to China would probably be on the high side, even if I, as a private person, can find a company to take them. Personally, I would argue that it's their fault and they shouldn't bother me when shipping faulty/non-new/wrong/etc products, so they...

Yes, 'full capacity' as per rated capacity stamped onto the cell, not as per claimed capacity by the seller and the company that resleeved these cells. ;)

I had a customer service rep from a Daly rebrander company say I had to update the firmware (via usb/pc app) on my 24v8s Daly and it bricked... The update system is shite.

AliExpress chat. Via a rebrander company. So it was a Daly, but I didn't actually deal with Daly.

I have a Daly Smart BMS (8s), purchased earlier this year, and it includes a low temp cut off, tested it, worked well.

Can you lift the black covers to see if there's a (scratched out) QR code with capacity specifications? If so, what does it say?

Finally able to use my JK, 8S, 2A balancing. Figured I had to assemble the 24V battery first, for a quick charge before I did the top balance. But assembled it, charge it slowly using a 10A power supply and when there was a cell over-voltage, let it rest for a while, charge slower, did that a...

Right, well, I checked with a DMM, it reported .4V lower than the Victron and lower than the BMS. It was very old, so I got myself a new one. Turned out the Victron shunt was correct, BMS was a bit off. Corrected that. btw, it's a single battery. Ambient temperature is 6C now. I changed the...

Personally, I had problems with wildly fluctuating current readings in the BMS (both Daly and JK) while using an 230V inverter/charger, this caused the BMS SOC reading to be incorrect. Luckily, the Victron shunt solves this and I can monitor the battery using the Cerbo GX and the shunt.

'balance slider' > it's not an interactive slider, but an indicator showing the BMS is balancing the cells 'cycle count' > going to (close to) 100% and going to (close to) low voltage cut-off and back up.
