Please note that after moving 16 of these from your porch to your installation location, you're probably going to need physical therapy, possibly a chiropractor, and that $10 Starbucks "Thank You" Gift Card to the UPS driver ain't gonna cut it......

How does one even connect this?? They only support 4 in parallel. Unless you do 4 sets of 4 in parallel and all 4 in series for 48v? Daaaaaang!!!!

Yeah, that's how you do it. I have 8 of them for 48v 560ah

63 lbs (29 kg) apiece; I agree. Not impossible, but one would definitely want to be very careful to use correct lifting posture throughout.

Question: When you choose to output at 48v, is that so you can quick-charge something at the sacrifice of the extended amp hours (runtime)?

Going up in voltage seems to have a few benefits. One that I personally know of is using thinner wires between the batteries - I guess lower amps through the wires?

Also efficiency is higher with higher voltage. meaning you get more out of your batteries when u convert to ac power. Also another reason why most power stations use 24v and higher voltage. Examples like ecoflow delta 2 and jackery power station mostly all use 48v battery systems.

U can use thinner wire. More efficiency due to less amps in wires meaning less heat generating thus less waste when hooking up to inverter. I usually don't like hooking 12v up to series anything more than 24v because you can get some cell balancing issues. That is why they sell series cell bms balances when hooking multiple 12v in series.

Those were good answers, but also remember that Ahs is not the capacity or runtime; it's Watt-hours. And in theory a higher Votage and lower Amps would have a slightly longer runtime since there is fewer amps running through the wires for the same amount of wattage.

So this has confused me in the past, a 12v 150Ah battery vs, say, a 24v 150ah battery....the difference between them would really only be in their ability to deliver higher voltages at any given time. But I also assumed if you have a load against a 12v battery the most you will get is 120w theoretically. However, if your device/load can pull 24v, you'd get up to 240w theoretically would drain the capacity twice as fast.

Eh...no?

No, you got to think of wattage, a 12v 150Ah battery is only half the size of a 24v 150Ah battery. You would need twice the power to supply 24v and 1 amp for 150 hours than 12 volts and 1 amp. Confusing I know. But Whs or capacity is Volt x Ahs. If you had 100 battery cells that were 1 Ah at 1 volts each for simplicity, you could arrange them as a 100v 1Ah battery or or a 1v 100Ah battery. or anything in between, and it would still be the same Whs and provide the same amount of electricity. here's a link to Will Prowse's video I'm sure many of us have watched. https://www.youtube.com/watch?v=cX4s-bxn4fs fair warning though, after you watch it, you are going to build something.
