15C is not enough for a tienly motor. You're overdrawing that pack or very close to doing so. 30C-1500mah or better on one or both values would be more ideal.

constant draw will probably be around 20-25A tienlys draw hot, so you can safely assume 50-75A startup amperage is needed with that motor. If you have stock gears you might see a bit less but I would err on the side of caution and go bigger battery. That also means you're going to run out of juice pretty quickly because the teinly will consume more, faster to drive the gun.


A little bit of anecdotal evidence: I had a 13:1 setup with a lonex A1, constant draw was about 22A. I would get about 1800-2000 rounds out of the battery before needing a change. Since switching to a zci motor, it's slower top speed so I lost a few rounds per second but the motor turns with more torque so reaches top speed faster, so trigger response is just as snappy as the lonex a1, but the amp draw is now 13A. The same battery lasts almost twice as long. Before I would have to change the battery at lunch time during a game, now in similar circumstances it lasts the whole day.
