My test was imprecise and incomplete because the battery was not charged up to the very maximum (14.2 vs 14.6) so it is somewhat higher than 285. Considering the cheap price and because it is 9 lbs lighter than the other 300ah batteries, I just wanted to make sure it was at least close to 300. The 100ah version tested above 100ah so thats a good sign. With the $200 off coupon (~$960 shipped), it might even be cheaper than DiY.
I have a bunch of Weize 100 Watts mono panels also and they seem like good build quality. They are the older style (~17% efficient) The best i saw was 92W in late summer New England sun, same as my Renogy and HQST mono panels so the Weize brand has been pretty good so far.
The main problem is that Will was unable to get in touch with them, even though he was giving them a great review on Youtube. They missed the ball that day.
