I build power boxes. I use 2. LiTime 12ah for 24ah. I put them in harbor freight ammo boxes, and some 12v outlets. For my CPAP machine, I use the 12v socket for my CPAP machine. I added some USB outlets, so I can charge my phone, computer, tablet. I added some lights, and of course the inverter and a battery monitor. Then I upgraded it, to charge by solar. You & I have the same ideas.
@@maurice7413 Yes I agree 12v to 240v for UK appliances draws too much amperage for a single battery. Even with several in parallel, it still consumes excessive amperage. EDECOA 3500W Pure Sine Wave Power Inverter Input Voltage (DC) 12V Output Voltage (AC) 240V
@@maurice7413 You can run a 240v appliance with a 12v battery and inverter. I've done it. It has everything to do with the battery amperage and really nothing to do with the voltage being 240vac as long (as long as you have an inverter that produces 240v - widely available). Why is current (amperage) the issue? If your appliance takes 240 watts, it will require 20 amps from 12v plus any losses in the system (often 10% to 20% adder). If your appliance takes 2400 watts it will require 200 amps (plus losses) from 12v. Notice I said nothing about A.C. voltage. That's because the A.C. voltage does not matter. With the voltage of the battery and the size of the load in watts, you can compute the amps required from the battery. And with a lithium battery, the amps are limited by the BMS. Personally I like a normal max of 1500w on 12v, 3000w on 24v, and anything more I do on 48v. I wish higher D.C. voltage inverters were more readily available. Trying to do a 48,000 watt system on 48v D.C. is silly, but that's really the only choice for a DIY using mainstream equipment.
When a 1000 wh power station with a 1500-1800 w inverter is selling for around $400 now, like a Ecoflow Delta 2 or Jackery 1000 v2, this is just not cost effective. Just my opinion though.

Sounds like a great setup!
Sweet and simple! Thanks for sharing.
Thanks. Have you made one or maybe going to make one?
@@OurBlackCatCottage I've made a couple and am currently working on one using a 48v battery and an all in one inverter. :-)
And a charger. Battery, inverter, and charger.
Optional.
@@OurBlackCatCottage you are suggesting that a power station does not need a way to get energy into it?
@@funkmon, umm, isn't the charger a/c plug or solar? Seems like nitpicking.
They also have a charge controller for solar.
@@mr.c6674 yeah, one of which was considered optional, the other not included. Which is shocking unless people buy these as one time use.
Could you switch to 48V builds and not these 12V. Thanks!
As soon as I get some 48v batteries and equipment.
Yes. Please move on to 48v!
The problem here with our 240v appliance a 12v inverter with a 100 ah battery would just draw too much amperage
48v setup would be a better fit for a 240v load.
You cannot run a 240v appliance with a 12v battery and inverter. It has nothing to do with the current.

Yeah when on sale but that is not often
Yeah if you can get one on sale it is worth buying. I just wanted to show that they are simple to make and you can save a bit of money.
I would not accept a free battery from them. Proper battery disposal isn’t free.
Thanks for your input!
