Samuel I. ★★★★★

The JST connector clicked right into place and the whole pack disappears into my build — genuinely impressed by how thin this LiPo is for a 400mAh. Charged it up and it held the nominal 3.7V without any fuss. Perfect little power source for compact projects.

Carter K. ★★★★★

Weighs just about nothing in the hand, and the slim polymer build slid easily into my tight little electronics pocket. That 400mAh capacity has been plenty for my short test runs, and the 3.7V output has been steady every time I've checked it.

Grace ★★★★★

The JST connector clicked right into place on my board, and the slim profile let me tuck it into a tight spot without any bulging. Charged it up and got the full 400mAh runtime I expected, no surprises.
