It puffed like the others. Funny, other brands at the time (same current and voltage specs) worked fine in the same setting and had no issues.

Maybe TP provides a better product today (regardless of the so-called warranty) but I won one recently in an auction at a fly-in (4S Extreme V2 2200mah) and it puffed just sitting around for a week or two. I know that I'm far from alone in my feelings about Thunder Power, and as it turned out those particular batteries (4000mah) had a history of problems. Next time I go to Vegas I need to stop in and say hello to those jerks.

I thought the Nano-techs were OK until I found that comparing performance data on different motors revealed, in addition, that the nano are NOT supplying the advertised power; this with 4 relatively new, lightly used, and in perfect condition 2S and 3S 5300 and 5000 mah (35-70C discharge) respective batteries. I'm not a battery expert, but I do know something about them and power calcs and the rest of it and I won't buy these again. No puffs yet, but rather sub-par as per advertised performance.

I'm beginning to suspect that one must spend the money to get good batteries or be a "name" using them so the company won't look bad. Also, keeping in mind that no matter how "good" a product may be, the way that a company deals with problems is just important. Now, what do I order next in the way of batteries??????? It seems like you roll the dice and hope that something good comes up. I still have some batteries (without balance plugs) that I bought 5 years ago that work great. WT-?

Who knows, maby they are now adding mouse pee to save on cost!
