The company where I purchased my solar kit showed the SOK battery SK12V206 out of stock, so I ordered directly through SOK. Given the lead-time upfront, I checked in about mid point on the order and received a courteous reply that it was still on target for delivery. Although they don't give you an exact date, being demand for their battery is high, I understand and they do a good job meeting there deadline, only about a week or two past when I thought I'd get it. I'd rather wait a little longer to get a quality battery, plus the price is good as well. I'll be hooking my system up this week, when I unpacked the battery I could tell it's good quality, and if the battery quality is as good as the care they put into packaging, I think the battery will be great. I'll send a follow-up after I've used my battery for awhile.
