testing new cells (batteries) from micro motor warehouse

learned about these cells for umx planes similar to the radian:

eventually finished performing tests on these batteries. just in time for fall to arrive with winds and rain
i used the hobby king nano cells for comparison https://hobbyking.com/en_us/turnigy-...kzone-etc.html
1st did bench tests using a umxradian and running the motor at half throttle (stick vertical) while holding the plane on my hand, and stopping every 30 seconds and taking readings of the voltage remaining.

i used the hobby king cell 160 mah as a point of comparison:

and the 1st 1 from micro motor is this: https://micro-motor-warehouse.com/co.../mylipo-150mah
the way i did the bench tests was installing the cell in the umx radian and run the motor at half throttle (stick vertical) for 30 seconds, stop and measure volts. then again. until reached the minimum recommended.

more power at launching
i must add that with all these cells there is a big increase in power at launching. to the point that sometimes the esc turned the radio off so must be careful.
just dont move the throttle all the way up at launching for the 1st flight with that cell.
so much power!
adapter
by the way, i made a connector to use the large connectors that come with the largest cells.
i used this piece: https://micro-motor-warehouse.com/co...ble-jst-ph-2-0
i removed a connector from a dead cell from hobby king and soldered it to this.
