Can get them from digikey: https://www.digikey.com/en/products...ZX4AnAJYA7AOYgAvvMIsyIgK5iAMkQDWAAgAKmNdm7ygA
Did you try their technical support email or the sales email?Thanks all helping me to find out what battery connector it uses.
Now if Ruixu support could be this helpful to let me know what it uses instead of just stop answering my emails when asking them.
I was just told in email that they do not have any inventory of 2 AWG cable.Waiting for them to reply to my request to get cables using AWG 2 instead of 4.
That is what I figured as well, and it would probably void the warranty to replace them. That really is too small for a battery BMS that can deliver 100A. Short leads of 4awg from the terminal to the bus bar in the rack would probably be okay, but I do not have a rack or bus bars.As the manufacturer of the cable can’t do AWG 2 then I believe the plug they use is the 5.7mm that can maximum fit AWG 4.
100A (5KW) would probably be ok with #4 in free air, but you'd probably want it to be a short interval. A 100A capable battery is not normally designed to pump 100A sustained output. Most of these units are engineered for 50% duty (50A). You can run them higher, and most quote 150A for a short burst, but ideally they perform better at lower discharge rates.That is what I figured as well, and it would probably void the warranty to replace them.

While all that is true, engineering things safely doesn't care much about how it operates under normal conditions. You >could< use a 30A breaker on 14 gauge wire too, because normally, it would be just fine, but you and I both know we don't always have control over the load. Unfortunately, that makes it something to work around on an otherwise pretty solid looking battery system. Will know soon, one on order.100A (5KW) would probably be ok with #4 in free air, but you'd probably want it to be a short interval.

It's under the NDA...Thanks all helping me to find out what battery connector it uses.

looks like SolarPowerStore.ca in Canada now has the floor mounts and wall mounts listed..Are these ok to use in vertical orientation - front face pointing up?
And now, after several hours, the finished product. I will get some proper sized cables and mount the inverter to the wall later this weekend.
The side panels come off too, but I don't know why anyone would ever want to take them off.
With most batteries ( rather bms'es) , soc is calibrated every time a full charge is done.So my 20kWh stack is connected to a Voltronic 6.5k singlephase unit using the "LI-b" battery-type setting.
It is in a backyard workshop that is not completly done so the gear is idle for the most part with few led lights, a laptop and a SA unit as a draw on top of the inverter standby burn.
The units stated 30% SOC I charged with utility when I first got the stack and charged them slowly up to 100%. Again, not much use over the last few weeks so voltage stayed pretty constant around 51-52 with less than a kWh of solar daily due to temp panel config and winter clouds on the west coast. This morning I noticed the stack voltage was below 50V and dropping fast yet the SOC was still reading 93%.. It just crashed out the inverter when it got to <48V so I started the utility charging again.
How do I re-calibrate the SOC on these Ruixu packs... I am guessing leave to fully charge until the BMS terminates the charge?
Thats what I was thinking.. maybe the initial charge did not fully complete properly. I will try that again. Very strange it died with 93%With most batteries ( rather bms'es) , soc is calibrated every time a full charge is done.
So easiest would be fully charging your batteries
