Great "tiny" battery

fits my needs for an ultra light battery for a rubber powered R/C airplane... meeting weight requirements... but connection compatiblity, out side the company products... ??
But... the connector is not recognized by the receiver, nor charger... need an adapter... TBD.. they do specify connector type - JST-sh.... charger does not, just assume you know? Receiver specifies Molex1.25 Pico Blade, protected male... yet to find a mate.

Amazing little battery.

I purchased this to fit underneath a Seeeduino Xiao BLE, and it fits perfectly. (See photo for a size comparison of this battery to a 301230, next to a Pro Micro based controller)


Works great
