Lithium Ion Batteries for RV Solar???

Just wondering could Tesla powerpack be used for Rvs?

Just noticed the price,so thats probably no no for most of us here..:)


How about some used Lion batts,,could those be made to work in RV?

Hi 2oldman,

Yes I do push my inverter to the limit. Particularly in load support mode when only a 15 amp shore power supply is available.

The power path is:

15 amp shore-->autoformer-->Magnum inverter/charger set to 12 amps--RV.

Typical winter time demand for winter time use, I may run the water heater (1200 watts) and fridge (325 watts). I run a Nuwave induction cooker (up to 1200 watts)--and I'll run the microwave (1551 watts).

Granted. Do you ever actually invert 3kw?

if you already own a 3000 watt 12 volt inverter it would take 3 of the 300 amp-hour jars or a whopping $10,500.00 for the battery bank.

2oldman,

Yes, series is the way to go--but if you already own a 3000 watt 12 volt inverter it would take 3 of the 300 amp-hour jars or a whopping $10,500.00 for the battery bank.

Basically it is 100 amps max output. Two+ in parallel should work fine.

I see. 100a continuous from one battery is pretty darn good. I think going in series with higher voltage is much better for big-time inverting.

There are some sources that suggest that LI may not do well with high current draws. For example, at least some 300 amp-hour LI battery banks, may only be capable of powering about a 1200 watt inverter.

Haven't seen anything like that yet.

Installation is no different from AGM as Li's can run in any position. It's the weight savings that's so nice.

Hi AMsolar is an interesting resource and extremely positive. However, by avoiding the negative it may some times be misleading.

For example--LI, while it can be discharged in cold, it may NOT be recharged.

There are some sources that suggest that LI may not do well with high current draws. For example, at least some 300 amp-hour LI battery banks, may only be capable of powering about a 1200 watt inverter. That's not enough for my particular use pattern.

So please take what AMsolar suggests with a grain of salt.

I am distinctly NOT an authority on solar.

What does the authority here on solar have as an opinion and any usage reports, installation differences from AGM or where to buy etc...

Finding good reads...

I use AGM and love them,
I think i would like Lithium, but the cost factor for equivalent amp hr, capacity/use is to much for me
I got almost 5 years or of everyday full-time use , out of my first set
Bought my second set in April this year

It would seem that lithium ion deep cycle battery technology has now matured to the point where they become the obvious choice for those expecting the most out of their batteries, EXCEPT for price which dissuades all but the most avid dry campers from even considering them. Recently while Down Under I visited an outdoor caravan show where it was obvious Australians are way ahead of the curve when it comes to the quality & variety of products being offered, including LiFePo4 deep cycle batteries which are readily available everywhere.



It really comes down to cost and whether the many advantages of lithium ion are worth it to you. Heck, not me, I even struggle with the cost of an AGM! :W
