The SOK website lists basic specs for each of their batteries. But, apparently the only place you can currently download detailed spec sheets is the SOK Facebook Group. I've attached the spec sheets for their two original 12v batteries (100Ah and 206Ah). Specs sheets for their two newer models aren't there yet.
IMPORTANT NOTE: both of these 12V batteries have the SAME max charge and max discharge limits. Those amp limits double with two batteries in parallel. However, I see a lot of folks assuming a single 206Ah battery is equivalent to two 100Ah. That is not the case. To power a typical 2000W inverter, you need at least two of these batteries, either two 100Ah or two 206Ah. The 206Ah gives you twice the storage capacity, but not twice the amp delivery rate. Storage capacity is still an important feature. I bought two of the 206Ah batteries to help ease recharge anxiety. So far, I like them a lot.
A couple things not clear in the spec sheets:
Under Balancing Voltage it says <14.4V. I found that odd given many BMS balancing systems only begin to balance at about that voltage. I asked the question on the SOK FB group and got an answer from the SOK rep. They said the SOK BMS does continuous balancing up to 14.4V. Apparently it's a real thing, but I don't know how it compares qualitatively to other balancing systems.
Although not listed in the spec sheets, the SOK rep also told me the BMS over-current cut-off is 130A. That's well above the recommended operational max of 100A. They said the 100A value was intentionally conservative. You should still use 100A for sizing your system and in daily use. It's just good to know there is some wiggle room in case you accidentally over shoot at times.
