Also not the double balance leads on one of the cell bus bars near the BMS. The V1 does not have this as it uses one less balance lead

Yes, that is true for the 8+ to 9- connection. I just didn't notice. Good eye there!

Haven't had my quota of scotch yet.
I ran into this changing out the original V1 BMS with the V2 supplied by EW. I have a JK BMS and it just so happens the balance lead/temp sensor wiring harnesses are the same

Wow you are all turning into trainspotters knowing the very subtle differences between each version LOL

The differences may be subtle, but they transform this product from a mediocre rack-mount battery to a top-of-the-line design.
The biggest obvious difference is the addition of Bluetooth and WiFi (though that antenna design is not great, and reception is poor unless you modify the antenna). In addition to that, the more subtle differences seem to be better cells and better cell-to-BMS communication, which leads to better (tighter) balancing results.

Well I didn't think we need to go here but here is another public service announcement.
Do not have the wire lug backwards where it could possibly touch the screw holding the terminal on. Give as much space away from any possible shorting point.

I was going to modify mine so I could access it from far away but then I reconsidered. I don't want someone out in front of my house accessing my batteries via Bluetooth. I like the idea that it only works 20' away.
It wouldn't take much to move the antenna outside the box. I posted the connectors in previous post but stopped myself. Solar assistant as a Read only option is good enough for me right now.
Just my personal though on this..

Should be more like Apple with very subtle changes you need a new phone
I think it's fine.

Yeah that is definitely more than fine, the OP in the other thread had them upside down and flapping around all over the darn place, even when he was tearing them apart to try and find out what was going on, both wires were still connected and flapping all over the place. I was just waiting for another explosion.

There were so many safety violations from my point of view there. It was a absolute mess. Just waiting for an issue.
But just like work we address everything. Make it burned in everybody's brain. Put notices above toilets of somebody doing something stupid and don't let that be you.
If you do something stupid and get hurt or blow something up, you're going to be in a notice in every toilet at work

I have a couple terminals "reversed" on purpose but my IQ was high enough to check for adequate spacing. Sheesh!

On further consideration, if he let it cook, it might have eventually cleared itself.

These tests took me over a week and I finally posted my video below.
Check out the capacity test results. I also mentioned this thread haha!

Good video Will. The only thing I’m curious about, is why you pronounce Vatrer like it’s a French word.

Basically my experience with the battery as well. Definitely some cell imbalance. I wish I had more to test as a control.

I think Bluetooth is better than a screen on the front.
While making my video, these posts were fantastic. Great points

I feel beat up but I was honest
I did get more after balancing and opening up the BMS capacity where it wouldn't stop the discharge. The BMS also stops full charge by counting coulombs and unless altered stops at 80% or LV Disconnect.I take all welded server rack batteries and run them up to 3.650V/Cell with an external power supply and active balancer. Saves days if not weeks off the process. No need to install one once everybody is happily top balanced.
After many cycles the E-W is keeping up with the Vatrer and LP4V1 (<2%) so it was a nice reasonably priced battery to add to my system.
I am not in a YouTube competition so no need to post anything there. I had a lot of fun at a reasonable price and they are working just fine. Looking forward to the 6 rack unit where I can add one more to my collection.
50ah x2 is much cheaper when on sale. And I was comparing to the ecoworthy when they were under 800. Now it's 840

they were under 800 last week so their marketing team is always changing it. May be when a shipment comes in and they get filled up the price goes down.
I almost went the 50ah but I wanted monitoring and the 100 lb size was perfect. I have a 19" rack fetish.
Oh no worries! I didn't mean to do that at all. No matter what I always have to question all information available to me on the forum and on the internet. It was very helpful all the data that you posted.I feel beat up but I was honest

What capacity test results are you getting with the vatrer? I'm testing those right now.
Oh I don't see you as competition haha I'm just trying to find problems with it. When people like a product, I make it my mission to find something wrong.
