MATH...what current am i running? IMR's

[tstartrekdude]

I made me a little monster, it was a Romisen rc-n3, but i put an m bin MC-e in it and am running it DD off an IMR16340(thank you AW) made it a twisty and put the biggest wire i could fit under the reflector with out shorting it out, and ground the reflector to focus the emeter.

So anyhow ,I don't have any testing equipment besides i big fan and a poopy multimeter, BUT i did a run time test today,the cells were fresh off the charger at 4.19 votls and i stopped the test at 8 and the cell was at 3.51 right out of the tube, and came back up to 3.55 with in a , i did the test with 2 cells with just about the same results.

so...what current am i running though this little beast, i don't know what curve these( or any for that matter) cells discharge at, my multimeter gives me 1.35 amps but i know thats WAY off.

i hope i am not killing my pore IMR's ,so any guesses would be much appreciated.

Your IMR cells won't even break a sweat up to at least 8C, so those are fine; the bigger issue is that you appear to have attempted to do a dead-short current reading on one, which would be sufficient to damage if not destroy your multimeter.

The 1xIMR123 M-CE setup is do-able, but don't expect runtimes to reach double-digits..

The maximum recommended current for the IMR16340 is 8C, or 4.4A. Thermal runaway will be an issue with your set-up, but I don't know if the current draw will reach 4.4A before the cell is depleted (I doubt it). You'll probably get 8-10 minutes per charge.
