Field report would be interesting here. Attractive price point but that flat/squared butt plate doesn't look like it'd do you any favors - whole gun will ride up on the corner instead of rolling in your shoulder like the PTS. Then again I'm a filthy CQB player who prefs thin stocks (magpul BSL atm) so maybe it's something you can live with outdoors

There's a couple threads here and here that dig into battery ratings and LiON vs LiPo specifically. It's not worth it in terms of return on investment, but if you happen to have a few packs on hand and already have the necessary tools... more data is always better than less
