First we need the plasma cutter.I can see it now, a CNC program to cut out and drill front panels for the display and antenna....

Just lay a wet towel on the batteries and components it will be fine.

I would strip the panel clean and do it in a milling machine. I have 17 of them and it simply is not worth the effort to do it. Now if it could be installed in the master and access the slaves, that would be very nice. I would only need to do 2 of them. The dedicated laptop is the simple solution for lazy me.

It would be more like a Dremel for me. I would be happy with a plastic box on the outside that I milled out. I don't need a display I just can't help myself when I see a open port. I want to stick something in itI can see it now, a CNC service to cut out and drill front panels for the display and antenna....

I think I may have voided the warranty on my EW Battery. I added two jacks to the front panel.
The top one is for the Daly 1A active balancer I installed. I can plug the Bluetooth dongle for the balancer into this jack or I can connect to my computer to monitor the balancer. I have the software "plugin" almost complete. I figure a 1 amp active balancer will be much better that a 60ma passive balancer plus I wanted to evaluate this balancer. There appear to be two flavors, the 100Balancer, Blue and the Daly, Orange, they both I suspect are the same. It has two UART ports. I also like @BarracudaBob wanted to extend the LCD port out the front. My intention was to install a jack and use the same LCD screen on a number of batteries. However, the V2 BMS has 12vdc power on two of it's pins whereas the older V1 had 3.2vdc. My LCD screen worked on the V1 but does not work on the V2 (communication error). I suspect the V2 uses either RS485 or RS232 whereas the V1 used RS232-TTL (will get back on this). If the 1 amp balancer works well I will be adding them to my six EG4 LifePower4 V1 batteries as this is a less expensive option than a $60.00 EnerKey 4A balancer (per battery) which would be a tighter fit. In addition I like the ability to monitor the balancer with a computer

I'd make a new face plate from sheet metal so you keep the originals intact for warranty purposes.

I always wanted to make another one for my EG4 LP4V1. So I can change the BMS out I would love for someone to do that I'd buy them I think there'd be a market for a popular battery brand. There is a lot of old ones showing up in junk pile and auctions.

Why wouldn't it work for V2? I doubt it is a voltage thing. I did try the JBD RS485 to USB adapter and it didn't work on the LCD port.
I had 2 of teh 100Balance units. Looks like a rebranded Daily. Both failed and sent back to Amazon.

10 years ago I might give that a try. It would be deionized or distilled so it would be non conducting water

The difference between 12vdc and 3.2vdc on the two power pins makes a difference in an RS232 or RS232-TTL communications. The firmware in this JBD may have also changed the protocol. Many batteries that use the same/similar LCD display also have firmware specific to the BMS they are connected to. For example the LCD in my SunGoldPower batteries looks the same with the same display data but won't work on the JBD. The LCD I bought from AliBaba (and his 40 thieves) worked with the JBD V1 but does not work with the PACE BMS or the JBD V2. Now that I have the port available on an external jack I can take a look at what is being sent on the RX/TX pins.

I forgot to mention. The 100Balance appeared to not work as I could not connect to it via Bluetooth. I plugged the Daly Bluetooth dongle into the 100Balance and it did work. The 100Balance Bluetooth Dongle may have been the issue as both balancers do work and can be monitored with the Daly Bluetooth dongle. The same balance lead wiring harness works the communications protocols are the same between both units.

Same problem I had The Bluetooth worked and I don't know if it's shut down or turned itself off but it never turned itself back on. Amazon prime returned it try it again same thing returned it.
The EnerKey been very good to me the 10 amp version I'm here in some problems about but the 4 amps been rock solid. The 15 amp which is very expensive and overkill I only use during initial battery testing.
Knowing what I know now the four amp is more than sufficient.
You guys are doing Awesome work
Quick question. Bought 4 DC house 165 12v that arrive tomorrow. Gonna get charged etc tomorrow. Should I just connect these in parallel with the server rack battery? Will the app automatically detect the added capacity? Do I need to change any dip switches ?
Thanks

I did a test of the DC House 165ah here back around Xmass I picked them up for under $200. I do not suggest putting 4 x 12V in series and them parallel without a balancer to protect if one battery gets low or BMS opens up. If one opens up you have -36V across a battery when charging. Something like the HC02 12V balancer is needed in my opinion. You can get it at 50% off of aliexpress. I like the volt meters but there are other version out there.
The other batteries will not detect the additional capacity. They won't drain as fast and their current/wattage will be lower but no magic in sensing what else is there unless there is communications between them.
Don't forget your T-Class fuses or breaker.

Well EW seems to be officially out of 51.2V\100Ah Batteries !!!
They are now saying they will ship the RS485 to USB adapter within 24 hours
and the batteries will be sent mid to the end of March!
We all know there are a few people who wont read that on the picture and will be shocked when their tracking number turns out to be a padded envelope.
Personally I see this as a really bad business decision. I suspect within a few days eBay will start getting complaints.
I guess they are taking a page out of their competitors playbook.

Since they now offer 15 packs (about $675/unit), I bet they'll run out of the next batch pretty quick, too.Well EW seems to be officially out of 51.2V\100Ah Batteries !!!

WOW, $675/unit! That is also 1,500 lbs too. That is probably one pallet off the boat. They are moving them pretty quick now.

Finally got it working. ESP32 + MAX3232. Figuring out how to decode current was a pain.

I coudln't wait to get it on the charger. I got it out of the crate myself. Charging up.
I'll move the new battery traffic to the new threat. Just wanted to announce it here

I was thankful I had an engine hoist if I decided to go this route. Be sure to explain everything, incl. delivery, etc. in your new thread!

I'll go take some more pictures. That was a serious box this thing came in. I assumed they were stacked because there was a bunch of sawdust on top. Zero signs of crushing. One hell of a crate box.I was thankful I had an engine hoist if I decided to go this route. Be sure to explain everything, incl. delivery, etc. in your new thread!
