This is the Xtrema Ultra-Micro Parallel Battery Adapter Set. This adapter allows you to charge up to 4 Ultra-Micro Batteries (E-flite® and ParkZone® single-cell LiPo batteries, and the Kyosho Minium Series) with any charger that supports 1s (3.7V) Lithium batteries via a standard JST connector. This adapter is designed to allow you to connect these 1-cell batteries via a JST connector to the LiPo charger of your choice. The adapter connects them in parallel, accommodating batteries of different capacities. By charging in parallel the only requirement is that all cells must be near their normal discharged state before connecting together and consequently charging. You have complete control over the charge rate, allowing you to choose a safe 1-hour charge for max battery life.

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. For example, if you either time your flights or fly till cutoff. You 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, 150mAh, 250mAh and so on. 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.

Want to do more than 4 batteries? No problem, get a second or third adapter and connect with a parallel Y adapter and charge up to 8, 12 or more! You are limited only by your chargers current capabilities.
