LG RESU10 for a mobile off-grid system?

FurTrader · Jan 23, 2020

I'm starting a new project of upgrading an RV with Solar and Lithium. Has anyone ever used the RESU10 in a mobile system?

The RESU10 is a 10 killowatthour lithium polymer battery with bms, etc, for $5,500

I'm seeing like zero DIY info on this battery. any thoughts?

its more geared for time off use abuse. I've never seen it mobile yet. Have seen a few users having to do firmware updates on them for lack of charging during grid outage. I'd avoid it in mobile for now and just order in standalone cells to build out. I havnt seen anyone playing with the settings yet or what you can do with the settings.

How big is your RV? A 48 volt system needs about 60 volts dc to charge by solar. Do you have the room on your roof for 300 plus watt solar pv? Sure you can series your PV but once one panel gets shaded you go to 0 watts. Also you need a 48 volt inverter and charger typically higher in cost to a 24 volt system.

Its a "expedition vehicle" called a Unicat. We are setting up for long term boondocking. Large battery, ground deployed solar. 2,800 watts worth.

Wow, just wow. I want pictures! I heart unicat bodys.

So how about we just get you some tesla mod S modules and the http://evtv.me bms/controller? It has much much better power to weight vs the LG.

You can also get a complete system from evtv.me with inverter and tesla modules. If your base truck 24volt? http://store.evtv.me/proddetail.php?prod=Powersafe15 not sure what kind of power you want? 120v single phase 240v? splitphase 220?

Currently in my driveway working on the project. We have actually decided that it needs to stay 12v because there is too much existing 12v equipment. It has a outback VXFR2812 and 4 4D 200ah AGM batteries.

I like the idea of Tesla modules, but this system needs to be more serviceable.

Either going to use 8 Battleborns or 32 of those blue “fortune” cells. Trying to get battleborn to sponsor the rig...

Fur,
I have my RV set up with 2 5.3Kwatt Tesla S 444 cell modules, victron 24/3000 Multiplus and 1100 watts of solar. The Teslas are set up in Parallel and i use 2 Electrodacus SBMS0s as my bms system. This takes up very little space and was very cost effective.

What do you mean by serviceable?

Keeping it 12 volt can be a mistake. Using 24 to 12 volt down converters is a simple task. The money you save in thinner/ smaller battery cable for 24 volts pays for the down converters. 24 volt inverters are more efficient.

24volt you also get to play will military surplus gear.

I’m putting the MPPT chargers right next to the batteries and nothing else will change. Existing 2800 va inverter will stay

The evtv.me bms unit uploads to the amazon cloud you can view stats and have a remote while the thing tours. just give it internet access.
