Cheap and Versatile Li-Ion Battery Pack
« on: March 08, 2018, 07:58:07 AM »

In Canada, these are sold through Marks. I picked up a couple this winter, CDN$10 each, intending to use them as hand warmers while flying. They have lots of other uses.

One possibility would be to use as a flight pack on glow or gas plane. You will have a 5.5 volt, 2000 mah lightweight power source. All that is needed it to grab a USB cable, chop off the appropriate end and install suitable servo connector to attach to your receiver, etc. As for recharging, any USB charger will work. This unit has an LED that shows if and when it is charging and will terminate the process at the proper time.
If you fly in winter, you could even put one or two of these in a LiPo pouch to keep some batteries warm and/or to prevent your field charger (such as a Cellpro) from going into "Cold Weather" charging mode instead of fully loading your LiPos.
I got caught with a low charge on my Mobius FPV camera one day out at thefield, but just plugged it into one of these and was back in business awhile later.

My purpose in Life is to serve as a Warning to others
