Nice!Now so many rack batteries are popping up. Check this one out:
51.2v 100ah Server Rack Lithium LiFePO4 Battery for Off Grid/Home Backup Solar | eBay
1 51V100ah Lifepo4 Battery(Does not include connecting cables and racks). You can see the battery status more visually without having to buy or use other tools to monitor it. Rack-mounted Design: There is a pair of portable handles on the front to help you better move your solar energy storage...www.ebay.com
I don't like them either. I read that thread. It was the crimp on the wire of the cable as I recall. Give me a nice bolt, flat washer, and a lock nut anytime.
Seems like most commercially sold server rack batteries are either Pace or JBD. They do the job. JK came out strong but not sure where they are at with new one. The new touch screen of the Overkill and JBD are nice. I haven't looked at the com protocol. I assume everybody does Victron or some major compatible type.Started new thread for it:
GoKWH 51.2V 100Ah review
Paid $885 all in for this through batteryfinds. https://batteryfinds.com/product/gokwh-51-2v-100ah-5-1kwh-lifepo4-lv-rack-mounted-home-battery-storage/ Took about six weeks from order to delivery from China. Some damage to one of the ears. Turned on fine. Biggest issue the damn terminals are...
There's a bunch of protocols you can select via the screen (for the gokwh).
I was planning on using ESPHome to connect to it over Bluetooth, but haven't gotten around to it. Ping me if you figure out a solution!!
I kinda grok that, but don't have headspace to go down that rabbit hole. If you're successful, please share! There's still the problem of getting it back to my server, which has a few walls in between my batteries...
hmm...

Clarke, actually. And an '80's hacker.
My bad . Thought Grok can from Stranger in a strange land..Clarke, actually. And an '80's hacker.
Can you help translate what's dangerous? And what tool are you using? I wonder if you got a different rev than others - didn't someone post they had 2 and 1 was different dimensions??
That doesn’t seem right for LIFEPO4..
The cell voltage should NEVER EVER go over 3.650 !!!!!!!!!!!!!!!!
This is the reason I like building my own packs…complete control. Although the price of these are very appealing, just need to watch out. Those default setting will definitely damage the battery and possibly your house.
So far my only complaint is the BMS settings. I liked it in the metal enclosure.
The Overkill Solar app lets you save the settings so you can easily load them onto other batteries? So you only have to type them all in once if you have multiple batteries?So far my only complaint is the BMS settings. I liked it in the metal enclosure.
I wanted to build my own battery but unfortunately time is is an asset. I don't have a whole lot of these days. You can do it. More power to you buddy. Make one for me and mail it
Overkill app has presets you can click on and write to bms. EZ, then I modified it.. Nice!
