Agree with this. I went with a single 200Ah but could not get enough amps out of it to run a 2k inverter. So I had to buy another 200Ah battery. Not the end of the world but expensive.Depends on your max amp draw, most 100 AH batteries have a 100 amp max power draw, when you have 2 in parallel they can provide a max draw of 200 amps, which you may need if you have an 2000 watt inverter, by contrast many 200 AH batteries, hav a BMS with a max amp draw of 100-150 amps, though a few do support 200 amp max power draw, so it all comes down to your needs.
A 2K inverter could be pushing the pair of 100s pretty hard. Much better with the pair of 200s.Agree with this. I went with a single 200Ah but could not get enough amps out of it to run a 2k inverter. So I had to buy another 200Ah battery. Not the end of the world but expensive.
Agree. My 3k inverter pushes my 2x12vx206Ah SOKs pretty hard. I'd be much better off with 3 or 4. Where does it end?A 2K inverter could be pushing the pair of 100s pretty hard. Much better with the pair of 200s.

Is it a SOK battery? Is it the new BT BMS?What was the battery? I'm hoping to run a sustained 150A for 5-10mins from my 200Ah battery when I get it - am I dreaming?
It's imperative that you match the battery max amp potential with the proper inverter. 100amp bms will be ok with a 12v/1000w inverter. That same bms will not at all like having a 1500w inverter hooked to it if you are pulling more than 1000 watts. Remember...AH (amp hours) is not what you need to look at when considering current draw. You need to know the rating of the BMS (100a or 200a).
For this reason I spent more to get a lifepo4 battery with a 200a bms (Power queen 'plus') in order to play well with my 12v/1500w inverter.
Proper gauge wires between your components is crucial as well.
Hi, I'm thinking of getting 3 SOK's 206Ah with a 3K inverter. As per your comment this should work fine, correct? I'd be using 8x100W panels.I have 2 x 12V 206Ah SOK batteries wired in parallel. I have a 3000VA Victron Multi Plus II inverter. With the old non BT BMSs, I have pulled 286 amps for 10 minutes and they worked great. With the new BT BMSs, I can only get 250 amps and they shut down. So a 3000W inverter actually needs 3 SOK batteries if they have the BT BMS.
A 3kW inverter on a 12V system can result in up 300A being pulled from the batteries. Those 3 batteries in parallel can easily provide the 300A. But you will want to fuse each of the 3 batteries.I'm thinking of getting 3 SOK's 206Ah with a 3K inverter. As per your comment this should work fine, correct?
