Good little Batteries, they work well with my Mobula6 2024, fast shipping too!

Has performed so far as a good quality 1S pillow cell with an A30 connector. Charge at 0.3 A to 4.35 V and store at 3.85 V. Was slightly disappointed on arrival, as the battery looked like a folded cell in the picture, with sharp edges, rather than the pillow cells with rounded edges that I received. But at 300MAH the battery is still small enough to fit the injection plastic battery holder in tiny whoops. (BTW - The A30 battery end will also connect to whoops that have BT2.0 connectors, but may shake loose in flight. Tried using a small elastic hair band to hold the ends together, but the electrical connection is still less than perfect.)
