Just finished my capacity test for the 100AH. First fully charged it, then I used my 12v fridge, which consumes ~40w. I ended the test when voltage under load reached 12.00 and 1307.1wh as you can see on the pictures. The voltage diff between cells are also acceptable.
For the ones who want to buy it: do it, won't regret it.
