and that 296 doesn't factor in losses through the inverter. More like 240Wh available to 0%, so call it 216Wh to 10% SOC.

Looks like it has a 10a and 15a charge setting.
Assuming that charger can charge at 15a, it may take around 3.5 hours recharge it form empty.
Do you know what is inside of these boxes? Is it just a battery with 2 cables to the inveter?

Thanks for confirming the charging amps. No one has been able to check that so far. So 15A (12.8x15=192W) will take (640/192) 3.33 hours in theory. Hopefully you are not using 100% of the capacity because that would be silly. I like the modular, as you could sell the battery and get a bigger one for example or just add another in parallel if you need more capacity. Also battery lasts 3000+ cycles.
I'm sure it's just the battery inside, you don't even need the box if you really on a budget.

Soooo tempted to buy one just to play around with. Can always use it for my camping and get rid of my old 800W DIY with Lead Acid box.
What is the wide/narrow switch at the back for?
Also wanted to ask about the wide and narrow switch.
Something to do with charging lfp vs lead acid perhaps?

AFAIK is to do with the incoming AC power. Wide is really shitty incoming power, narrow is power that doesn't fluctuate too much. I would keep it on narrow.

Looks very cost effective. Does anyone know how long it takes to recharge?

Nicely done, I would add "gel" into the LA group aswell.
I would also adjust the wording about cycling lithium deeply affects the life cycle because it isn't really true. 3000 cycles is rated at 100 DOD at 1C (in most cases), so they are absolutely hammering the batteries (100A) in their tests then after 3000 cycles you still have 80% capacity left. I would emphasize the issue with LA's though and that they don't like heavy loads.
Also add in the Peukerts law that effects LA's but not lithium.
Another thing to add is the recharge time of LA (long absorption) vs LFP (no absorption).
Hope that makes sense?
15A? Isn't it 50A?
Thanks.

I look at product specs on the actual site, or at least some actual information from a manufacturer. I'm not going to make any assumptions on what a product offers based on an estimate by a forum member.
