Use your 1S Lipos on your Beast!!!

This is the Beast male connector wired to two (serial) 1S Lipo Female connectors.

Plug in two of your existing (and numerous) 1S Lipos and then place in your Beast, and fly!

Then you could charge with your stock Beast charger, if desired. Or charge each battery separately.

Made small/short to save on weight - This particular one weighs .47 grams, yours will be very similar.

Note that the Eflite UMX Beast, Eflite UMX Sbach 342, and Parkzone UM F-27Q Stryker 180 use the same batteries and therefore the same battery connectors.
