Charging Server Rack Batteries with EG4 Chargeverter

Hello,

This is my first post. I've been watching Will's videos for a while now, and am dipping my toes into the off-grid power scene. I purchased some gear during the black Friday sales, and am now looking to set it up. Because I know that I should not let my batteries run down, I plan to set up an entire off-grid system but would like to charge up my batteries using n EG4 Chargeverter in the mean time.

Here is the equipment I have that is relevant to this post:

EG4 Chargeverter GC
2 x Epoch 48V 100Ah 5.12kWh - Self-Heating Server Rack Lithium Battery

The first part of my question is whether or not the following seems like an acceptable way to use the Chargeverter to charge my batteries. The Chargeverter has a NEMA L14-30 plug for connecting to a generator. My plan is to connect it to grid power using a NEMA 14-50 plug in my garage for charging my EV using this adapter cable.

The next part of my question is in regards to connecting the Chargeverter to my batteries.

The Chargeverter comes with these connection wires:

My batteries do not have ring connections on them. They also have the quick connect plugs that one side of these cables have. I have seen YouTubers using this cable to connect to a bus bar then using another cable like it to connect from the bus bar to their batteries. Would it be possible to just use battery paralleling cables to connect directly from the Chargeverter to my battery, eliminating the bus bar entirely? If so, could I use a second battery paralleling cable to connect my two batteries together and charge them at the same time using the Chargeverter?

I appreciate any advice that you may have.

Thank you!
 
That AC adapter cable looks correct. Be aware that if you try to plug the Chargeverter into a 120VAC receptacle you CANNOT use an off the shelf adapter. You'd need to make your own adapter cable following the 120VAC wiring pinouts indicated in the Chargeverter manual.

I can't comment of whether the quick connectors on the Chargeverter are the same ones used on the EG4 wallmount or the Epoch. It looks the same, but... perhaps buy the parallel kit from a vendor where you can return them if they don't fit?

Regarding your parallel question, yes - you can charge a parallel battery bank connected simultaneously using the Chargeverter.

Yes, to everything. Assuming that the connectors on the parallel battery cables are the same size as the chargeverter.
