Can I use a 2s battery from my mini b? It’s the protek one. I don’t have a discharger and it would take forever for my 5000 to discharge at 2 amps. The mini b one is 1100. Is that enough for just testing purposes?

thanks

No, because the pack will have too much voltage sag. It's better to use a pack rated higher than 6000mah.

Which analyzer do you have? I use a 4000 and it works just fine. When I'm testing multiple motors, I have another 4000 as a backup.

Voltage sag at no load will be very small.

The skyrc one. I plan on only doing one at a time per charge, not multiple in a session.

I see no issue with using the 1100 for a single motor run. You're not putting any load on it and you're only running it for 10 seconds. Heck, we use to run 27t motors on 1200mah batteries for 4 minutes, with a load.

your bringing me back to when I had to save all the cash I got for christmas and buy a 1600mah nicd. maybe a 5 minute run

I started in RC in 1982 with a 12i and we would run the 1200 mah nicads for 8 minutes. The trick was to gear it just high enough that for the last lap you were running slower but not dead.

And back to the OP, it looks like the mini B battery is a 2S 650 mah. That will work perfectly fine. The motor runs unloaded, it doesn't pull hardly any amps.

Yup!
I remember those days. gear the motor to dump at 5 minutes. Many will push it to 4.5 minutes, but often end up suffering an early battery dump before the 4 minute race is over. those motors would be smoking hot after each run. We had to come up with all kinds of heatsink designs to cool them off.

Ah... the good ole days.
