Ultra-Micro™ Battery Adapter

Use Your Charger to SAFELY Charge up to 4 Ultra-Micro™ Batteries at a time!

• Tired of buying AA batteries for the included charger?
• Wish you could use your own lithium charger instead of buying yet another charger?
• Afraid that charging at 300 ma is shortening your battery life?

The E-flite® and ParkZone® Ultra-Micro™ Aircrafts have taken the market by storm. It seems the more of these little gems you have, the more batteries you want and need to manage.

Our little Ultra-Micro™ Battery Adapter is the simple, cost effective way to charge these little batteries quickly and safely.

HOW IT WORKS

The adapter simply allows you to connect up to 4 batteries in parallel so that you can charge them as a single larger ma single cell battery (i.e 1s4p). The only requirement is that all the batteries be reasonably close in charge level. If you time your flights or fly till cutoff that is close enough. You simply want to avoid connecting a fully charged battery to a group of discharged cells, since a rapid rush of current would occur.

As you plug in the batteries they will be tied together and will self balance. Then connect the JST connector to your existing charger that supports 1 cell (1s) charging and set the charge ma. to the sum total of the mah rating for each cell. You can even mix 70mah with 110mah. Since they all receive the same voltage each cell only takes the ma it needs to charge to 4.2 volts max.

For example: If you have a 70mah and three 110mah batteries you would set your charger to 70+110+110+110= 400ma. At this current they will charge at the safe 1 hour rate, but since you have four batteries at once, they effectively take an average of 15 minutes each.

Charge up to 16 batteries at the same time!!! Yes, this is how. You need 4 of the Ultra Micro boards and 1 of our JST Parallel Charge cables.
