Via 120vac shore power, using a Victron 48V MultiPlus UL1741 3k 120v Inverter 35A Charger, how long should it take to charge one or two SOK 48V 100Ah PRO Server Rack Battery(s)?
Well you could turn the breaker off on the one you didn't want to charge.Would there be anyway to wire the system so you could isolate batteries so you could focus the charging to one battery only?
Not sure what he's trying to accomplish but def want them at similar states of charge before connecting them together in parallel. Easiest would be fully charged 1, fully charge 2 then parallel.Would it be better to charge the packs together?
You would wind up with separate packs sitting in a different state of charge when done separately...

Curious could I use a 15amp 120vac outlet from my house, or is more amperage needed for this Victron charger? Also not sure if the Victron could take 240vac for the charging application.Quick, rough estimate: Most chargers are rated by how many amps they put out per hour. You have a 35A charger. It will put "approximately" 35 amps into your battery, per hour. If you have a 100ah battery, totally depleted, it would take about 3 hours to fully charge. Two batteries depleted, double that time.
You can use the powercontrol setting to reduce the amperage draw on the grid input to say 13A and use a regular outlet. Out of the box it will draw up to 35A I believe.Curious could I use a 15amp 120vac outlet from my house, or is more amperage needed for this Victron charger?

So, would that also mean that the charger would put out less if only 13A was input? And the charge time longer?You can use the powercontrol setting to reduce the amperage draw on the grid input to say 13A and use a regular outlet. Out of the box it will draw up to 35A I believe.
If it's a 120V Victron you can't give it 240V.
So that's 13A of 120V, so say 120*13=1560WSo, would that also mean that the charger would put out less if only 13A was input? And the charge time longer?
Yes, I could add a 20A breaker. Thanks for your help on this. I will probably do that for sure. Farily easy to do that.Not sure if you can run a dedicated 20A circuit for your mobile hookup AC in. Then you could limit it to say 18A and be close to maxing out the 35A charger. Alternatively use something like a chargeverter (up to 100A of charging) to charge both batteries quickly).
You connect it to the power bus, easiest would be say a lynx distributor. 4 connections Inverter connects to it, the two batteries and the chargeverterYes, I could add a 20A breaker. Thanks for your help on this. I will probably do that for sure. Farily easy to do that.
But you're saying that I could add this chargeverter device to the Victron? Would you mind providing a link to that?

EG4 Chargeverter GC - 48V 100A Battery Charger - 240/120V Input
Revolutionize the way you charge your batteries with the EG4 Chargeverter - a cutting-edge 48V charger boasting a charging capacity of 100A or over 5kW!www.currentconnected.com
This will let you charge your two batteries at 50A each, around two hours and you'll have both batteries charged. So you won't have to deal with extension cords and 6 hours of waiting. Do you have a 240 outlet in your garage? That would be the ideal connection for full charging rate. It can work on 120V but not at the 100A output level.
I don't have one but looks like decent length on the cables and they are detachable on this one (older yellow model isn't). Be aware they are loud due to small fan but doesn't seem like you are living with it like a camper etc.Thanks!
Yes, I do have a 220vac outlet in the garage.
Could I keep this out of my van and in the garage all the time. I looked at the spec sheet, I think it says this is only 13lbs. I probably could find the space in the van for it. It looks bigger in the website picture but the spec sheet says it is approximately 5x5x13 inches. Might be best in the van as I could use a generator to charge with it.
If I was going to get this is there another Victron option I could use without a charger? Since I assume if I was using this I'd not be utilizing the Victron charger, that I'd be bypassing it?

There are Victron pheonix inverters with no charger but they don't get into the larger sizes like a multiplus or quattro. Stick with the multiplus, plus then that gives you the flexibility of 120V charging at a slower rate if away from home and you don't want to fire up the generator. For example if you are doing a renovation type job may be able to plug in to an outdoor outlet etc and get a little charge that way.
