I ordered 5Ah pack. It has vtc4 5s2p with ZK05 date (05th of Nov. 2017) that makes it 4.2Ah, basically 4Ah battery. I would expect Samsung 25r to make it 5Ah battery. At least it has Sony cells (hopefully genuine) instead of some no name Chinese battery. 3 out of 4 bars were on at 18.95Vs. which means 3.79V per cell. Close to storage voltage. that pack could theoretically give out 60A (but I doubt that tiny control circuit could provide that much current). So, instead of such hi current cells, they could have used less current more capacity cells like samsung 25Rs. Anyways I got it from BG, because of direct mailing option, which includes taxes, and it is faster shipping.
I don't think it is 6ah as the listing claims. According to my estimates, it has only 4ah capacity. That's because it contains ten 2000mAh cells in 5s2p arrangement.
