I posted a few threads on here asking Lithium advice. My dilemma is my 2022 Kontiki came with 2 Yuasa 100a/h leads, I have 2 x 100w solar and use a 2000w inverter for a 800w hairdrier. The set-up is OK, but in winter I reckon 3 days off grid and I'm struggling. So my first plan was more solar, B2B and Lithium upgrade so depending upon battery size I'm north of £1500 maybe £2000. Anyway had a rethink, and I've purchase (Not delivered yet) an Ecoflow Delta 2, this is probably around 70a/h of lithium after losses, my thought being when my leads deplete to around 60-65% SOC I'll be able to top them up hopefully fully charged. The eco can be recharged in just over an hour, weighs only 11kg so off to find a pub with permission from the landlord and a tip of course recharge, and I am good for another 3 days..... that's the plan, any thoughts, ill do this till I eventually retire my leads and then upgrade

Thoughts are, it gives you more capacity, but takes up payload and space which a lithium upgrade wouldn’t. It’s also faff which I would always try to avoid.

I have a Bluetti EB55 as my reserve power source...
Bought it when I still had LA battery...since gone Lithium, more solar and a B2B charger...the power pack still comes in very handy to supplement what's fixed..

Have you considered hybrid? I had a similar issue as we like to be off grid but use a lot of mains appliances. We had 440ah Gel (not sure how old) and 600watts solar powered by its own 12v alternator (chassis has separate 24v alternator). Main issue we had was voltage drop with heavy inverter use. Following advice on here from bigtwin I explored the hybrid route that some of the boating folk have been using, that is I replaced one of my Gels with a Lithium with a good BMS. I've now done over 2000 miles and 30 nights have to say it's working pretty well, the voltage holds up much longer and the remaining Gel acts as a buffer for the alternator. The only downside I can find is the alternator charging drops off a little earlier as the Gel battery fills. I may well make some further enhancements but cost so far is £860

I have a Delta mini. The main function in the motorhome is to run a hairdryer and occasional microwave using its own 1400w psw inverter as my present single gel battery is insufficient to run an inverter . No room for more batteries. It's quite light and I use it at home as well. It can be fully charged in just over an hour.
I have used it for battery charging when my batteries got low during the snow in storage, but the capacity is not sufficient for anything like a full recharge.

For a start using you 800 watt hair dryer from your L/A batteries is well over stressing them so they won't last long, you shouldn't discharge leads at more than the C5 rate.
With the cost of 100ah Lithium now below £400 you would be better spending your money on a proper Lithium setup.
Also these Ecoflow and similar unit do not use LifeP04 batteries so nowhere near as safe and can be a fire risk.

That’s providing you know what you are doing regarding fitting everything yourself

You try getting a price from a firm for fitting x1 lithium and the extra stuff required. The only 4 in the quote will be the second digit.

I have the original Ecoflow Delta,which I find really useful when in one place for more than a couple of days in winter. I have recently bought one of there folding solar panels to recharge it when possible.

£1500 to £2000 for lipo?

300ah now about £900.

I am no battery expert but the portable power pack is only 70ah you say? So for £900 you could have 12 days based on your figures.

Very true of most of them but there are a few exceptions. Bluetti have had some LiFePO4 models in their range since 2021 and Ecoflow have recently launched their Ecoflow River series with LFP batteries. When I bought one in 2021 for home use I ruled out all the models without LFP which limited me to only a few Bluetti models. I suspect many of the other manufacturers will be pushing hard to go over to LFP asap.

Saw this in Costco the other day. Only a 2 year warranty though.
Edit. Should have said I believe it’s the older version of the Delta 2.

I know one of the marketing points is how it recharges from 0 to 80% in an hour - but should be remembered that it only recharges that fast because it is a small battery ;)
The Lithium side of my Hybrid system will take in more charge Ahs per hour than that (sure, the percentage charge will not be as great, but that is because it is 3 times the battery capacity).

These Ecoflow systems and the like are pretty nifty and certainly have a place - but I honestly don't see that place as being in a Motorhome that is already fully fitted with Leisure Batteries, charger, inverter, etc.
Tent Camping? 100% brilliant. Motorhoming? Nah.

I try to do all my own work, I'm fairly handy and the quotes were with me doing it

Exactly...but also can it be Solar or B2B charged whilst travelling...

Solar charging should be possible. Most of them come with a solar connection cable. I doubt that B2B is possible because the internal batteries are usually higher voltage packs, well above 12V.

The power pack is 1050 w/hr so around 82a/hr but Ecoflow don't quote that figure. 1050wh Divide by 12.8a/hr = 82 a/hr. 2 x 100ah batteries taken to 50% SOC would be 100AH used so I think at around 65% ill get a full charge for £1099 Labour 1 hr while a drink me Pint

You are correct 300AH £900, Sargent battery charger not up to fully charging Lithium so either upgrade the battery charger or install a B2B £200-400, remove 2 brand new Yuasa batteries at £200 each and sell on Ebay to be insulted at 30 quid a battery!!! Labour 2-6 hrs

Its bought now so ill update this when I see if it works as planned

The OP stated in his first post said that this is an interim measure until he is ready to swop out his current LA batts for lithium, if it works out the Ecoflow can be sold on. So on the face of it a good idea for the OP but not eveyones cup of tea due to their individual setup. Like the boss Jim said, "Marmite"

It will be interesting to see how it works out in the end Fatboy

1 tonne payload so no problem
Click to expand...
TBH, even if I had no payload issues (I’ve nearer to 2.5T on mine), the faff and storage are more than enough of a deterrent for me to consider using one, but hey, never say never! 👍🏻

Some good point raised by others too! 👌

I've been looking at these for a while now, saw the one in Costco the other day too which reminded me. It'd be mainly for charging the ebikes when we're somewhere off grid for a few days. I guess we could also use it for the Tassimo, but I can't see us bothering to either lug the thing inside (14kg-ish) or unplug the machine and take it outside to make a coffee. Ditto my hairdryer...plus when I'm on holiday I often don't bother even when we have EHU.

So we're back to it being just for the bikes....they have fairly small batteries so need charging more often but we've not taken them away on a trip yet so we don't really know whether its going to be an issue or not. Long term I'd love to upgrade to lithium plus an inverter - but although the price has come down a lot, its still pretty expensive if you're starting from scratch, so one of these power packs might make sense as a quick/cheap(er) fix. For me the attraction of these things isn't so much the power pack side (because we already have batteries), its because they've also got a PSW inverter.

I did have an Ecoflow River Pro for about 18 months, was really useful at times and was pleased we had it. Just before Xmas I went to use it only to find it was kaput. After a couple of emails Ecoflow sent me a return label and to cut a long story short I was given a full refund. Thought that was very good customer service.

I accidentally flattened my Bluetti when I first had it. I think I must have knocked the on switch when putting it away. Since then I have left it in eco mode so it would shut down automatically if I did it again.

Now that Ecoflow have started introducing new LFP models I might well have chosen them above Bluetti. The new River series includes a nifty automatic change over from mains to inverter output in the event of a power cut. A few months back they were doing hefty discounts on some of the older models with Li-ion cells (not LFP) so if buying make sure you get one of the newer models.
