Upgraded to 4x100ah lithium batteries + inverter

In preparation for being able to boondock, I started to convert my RV park queen to be better equipped to be able to go without hookups. I just finished the biggest part- installing 4 Battle Born Lithium drop-in batteries, a Victron battery monitor, and a Xantrex 1000W inverter (as well as fuse, disconnect, and circuit breaker). Between the batteries are 1/0 awg cables; between the batteries and components are 2/0 awg cables; and finally the inverter is wired up with 2awg cables (it came with the inverter when I bought it).

I posted info on my FB page (you don't need Facebook to see it) at:
https://www.facebook.com/LearnToRV/posts/1446692428731506

And I have a real awkward video of me talking through it at:
https://youtu.be/sF9N7XK7WJM

I also have a full parts breakdown of everything I used at:

Hope that is interesting to someone. ๐Ÿ™‚

(Yes, I know lithium batteries are stupidly expensive- for me their benefits vs. AGM batteries outweighed their cost.)

Well, solar charging and an RV is like peanut butter and jelly, to me. I like getting out there and running a generator ruins it. You and the Mrs. are heavy users so size your solar carefully and add more than what you think you need.

FWIW, I run a 120V fridge, 120V entertainment gear, and all the 12V off one 235W panel and 300 AH of battery. I'm also using a Xantrex 1000W inverter and the thing is the shiz, absolutely reliable and quiet. ATM, also doing the cord thing but I'll upgrade to a transfer switch/s when I get to the next battery upgrade. Jealous of those Lithium batts, good luck with them!

How much solar do you want to add? You could use flexible panels and each 100 watt panel weighs 4 lbs. 400 Watts of panels, controller and wire would be less than 100 lbs for sure, probably closer to 50. Iโ€™ve never even considered weight when adding solar.

Yeah, there was no getting away from it. It was funny, we all complained to each other (I was friends with the 5 people surrounding me)- but it was just part of the experience. You wanted your windows open for the coolness, but down the line- one person started their generator and that neighbor had to close their windows. Their rig got hot, so they'd start their generator to run the A/C impacting their neighbor who did the same and so on.

I just got done with 2 weeks of dry camping at the Albuquerque Balloon Fiesta.

I've learned a few things:

1) We use a LOT of electric but also performed no attempt at conservancy. We would use anywhere from 200Ah - 280Ah each day after the generator + battery charger were turned off.



The Bluetooth enabled Victron BMV-702 was awesome. I loved being able to glance at my battery state from my phone any time I wanted (which was OFTEN being our first trip out).

2) My Progressive Dynamics PD9180AL charges the battery at an average of 40-45Ah. It starts at 60 but quickly drops down into the 50s and ultimately settles down lower. This means, to recharge the 260Ah, I'd need to run the generator around 5-6 hours a day.

3) Having 2 generators was nice. Friends with built-in Onan 5500 generators used 2x-3x the amount of fuel I did. I was able to run a single Honda 2000 a vast majority of the time. We only ran both if we wanted A/C or if we wanted to run 2 high use appliances at once (A/C, battery charger, microwave, etc.).

4) My little 1000W Xantrex inverter was a dang workhorse. I cheated by turning off all of the breakers and taking an extension cord from the output of the Xantrex to the camper's shore power inlet (with a 50-to-15 adapter). I could run most of the camper's outlets on it including running one of the following: ice maker, toaster, curling iron, hair straightener. (Actually, my wife had both the curling iron and hair straightener at the same time and it worked.) BUT, I couldn't run the 800W microwave.

5) Cheating with the inverter's power cord got annoying after a while. It was annoying to have to switch cords at the camper to switch between generator + inverter. Plus, more times than not - the GFCI on the inverter would pop and I'd have to reset it. If I stick with this inverter, Xantrex has very small single-breaker automatic transfer switches; I'll likely delve into installing them.

6) Generators are ANNOYING. There is no such thing as a quiet generator (unless maybe with a custom quiet box). My Honda 2000s are annoying loud. My neighbor's 3000W Inverter generator seemed quieter but was still annoyingly loud. Neighbors on both sides had Onan 5000 - they were annoying.

On top of that, the exhaust was insufferable with the nuts-to-butts closeness of parking. Genturi's / DIY solutions to lift exhaust should be required.

7) Per #6, I absolutely want solar now.

๐Ÿ˜Ž The LowPro LockDown is the bomb diggity. I was able to move the generators from my truck bed to the bumper and securely lock them in place. Expensive, but awesome. Here I'm test fitting everything for the install:



And finally- the ABQ Balloon Fiesta, tight quarters and all was AWESOME. Here Grandma and Grandson are checking out balloons from the field:

the initial investment is way more but when you factor the life of the LION batts, the fact that you can discharge them 100%, the weight and space savings,how quickly they charge, when you compare everything "apples to apples" the LION batts are much cheaper per amp hour than lead acid or AGM's.

A few corrections here.
1) Not 100% discharge. 75-80% is more likely, if you want them to last. (And max charge is also desirable to limit by 80-90% of nominal capacity).
2) Cost should be compared "per cycle", not per AH :)... Flooded are probably cheaper per cycle.

Faster Li in the last 15-20% of charge, yes.

OP - how are you going to charge them?
ps: sorry, have just noticed the answer - generator. No further comments.

Agreed. Times I've emailed them- I've gotten email responses quick. Each time I've called, I got a real person immediately AND they've remembered me from call to call (yeah, I made a couple).

I like their customer service, their price, and hopefully the longevity of their product!

Thanks westend and iterant.

The initial plan for recharging is to run a generator. I got it in the event that I want to run a high-load device like the A/C.

I upgraded the converter/charger to a lithium-aware Progressive Dynamics charger. Iโ€™ll use that.

At some point, Iโ€™d like to move it so that it is closer to the batteries so that I know there is properly sized wiring between it and the batteries. But for now Iโ€™m relying on the stock installation.

Nice job ependydad you'll enjoy the extra power. Lithium might cost extra but the benifits make it worthwhile. How are you going to recharge them?

I have the same inverter and battery monitor. They are still working great into year 5. Unfortunately, no Lithium for this guy. FWIW, with solar and 300 AH of battery capacity, I run a small 120V fridge and all my entertainment devices.

Good job on the installation! Everything looks durable and well placed.

Thanks profdant139 and htwheelz67. htwheelz67, you hit the nail on the head as to why I preferred lithiums.

The other side of the coin is that they recharge faster and more efficiently- you can make better use of generator time OR make full use of solar coming off of the roof.

From a discharge side, I've been reading 80-90% not 100% but still- way better than 50%. What I really like is the lack of Peukert on high-draw uses. If I upgraded my inverter, I could run my A/C for a short time or not worry about microwave/toaster/InstantPot use.

Lots of benefits. The downside is initial money outlay.
