Rethink on Lithium upgrade, I bought an Ecoflow Delta 2

[Fatboy]

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

Why do you need a full charge when on hook up? Bit of a pet topic of mine but people seem to be spending lots of money making sure their new LiFePO4 battery is fully charged on EHU. This is old lead acid thinking. Unlike lead acid (especially AGM) you will not damage a LiFePO4 battery by undercharging it, in fact they are better left at 80%. I would spend the money on a good B2B so that you have a full battery when you don’t have EHU.

Sorry I think that read wrong, on hook up was at home to charge the batteries before going off grid

It's spending not investment! The only people who call spending investment are politicians!

It will save me money in the long term, as will my solar panels.I'm losing money if left in the bank.I'm happy with my "investment" thanks.

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.

Via my inverter connected to my leisure lithium....or just plug into a 12v cigarette lighter outlet...solar is connectable via a freestanding or diverting the roof mounted tilting job...
