After 3 weeks in use can not say a lot about the quality of it. After all, capacity, charging and discharging behavior of 3 copies very similar and they correspond with the specifications agreed in the data sheet, which is not included, but can be found on the Internet. I have connected the 3 batteries in series, thus reaching 18V and operate a cordless chainsaw whose LiPo battery is not really useful at the low temperatures in winter. Loading the batteries with me one after the other with a pulse quick charger. It so far has no appreciable heating or outgassing determine. Because no final assessment is possible for now only 3 points.
