Excellent runtime of Malkoff M60 module

Halo,

Just out of curiosity I diecided to try how long the Malkoff M60 would continously run with diffrent batteries.

The host was bored 6P with two bored A19 extenders, fresh charged AW 17500, 18500 and 18650 batteries. I knew even with 17500 the runtime is somehow around 1,5 hour but I was wondering if it will manage to stay on for this period continously.

So I started with 17500 and... I havent even tried the bigger batteries as I'm just totally impressed. The full 2 hours and 15 minutes of runtime with 17500 batteries until the battery protection kicks in. Fantastic!

I'm not even sure I want to try further I'm so impressed. Suppose M61 runs even longer than that. The heat was not a problem, it was quite warm but by any mean hot.

I will get back with the result if I try biger batteries.

Well the M61 uses about 13% less power & produces about 11% more lumens than the M60.

This is good, more data is always appreciated. :thumbsup: I've been wanting to do something like this myself.

BTW there is an excellent thread called Malkoff M60 & M30 Runtimes,etc by gsnorm, virtually all of CPF's Malkoff runtime data & related info resides there. If it's OK I'd like to 'report' your post so we can get this (and any other data you get) merged in that thread.

BTW you might want to refer to your tested configurations as 2x17500, 2x18500, etc. This is because there is also a small contingent here who run their M60's on single large LiIon cells (like 1x18650) for slightly reduced output but greatly increased runtime, obtaining gradually declining output at the end of the run rather than an abrupt shutoff when one of the two protection circuits trigger.

Thanks,
K

I would like to find out the run time for M61 with two 18650 in Surefire 9p with extender.

An M60 with 1x18650 is my preferred setup too (over 2x16340), for the added convenience and run time. The M60 is bright enough for my needs and I consider any output differences to be negligible.

2x18650 is also easily within reach with a $5 solarforce extension.

Reminder: 18650's will not fit in a stock Surefire 9P (unless it is bored out), only 17670's will. You would also need to purchase a bored out extender as well.

I assume you mean the M61's runtime on 2x18650's, but not necessarily in a Surefire 9P? I think you would get in excess of 3 hours runtime.

I should have clarified - yes it a bored 9P with bored extender done by Electronguru here.

The bored 9P with bored extender is a great setup. It is worth the investment because of the power option versatility.

With the extender you can use 2x18650. Take it off and you can you can use 2x18500 or 3x123.

Even not bored out, having a stock 9P with an extender gives you the 2x17670, 2x17500 and 3x123 options.

Real runtimes are always welcome here on CPF...thanks for your efforts...we like to keep the MFG's honest (or at least get honest out-puts/runtimes). Welcome to CPF BTW!

Man, I need to get a real R/C Set-up...

Here are the numbers from my last round of testing:

• Malkoff M60 MC-E + 2x AW18500 = 70 minutes of continuously high output (9P/C3)
• Malkoff M30 + 1x AW18650/26 = 105 minutes of continuously high output (6P/C2)
  Malkoff M30 + 1x AW IMR16340 = 20 minutes of continuously high output (3P)
  Malkoff M30 + 1x AW RCR123A = 30 minutes of subdued output (3P)
• Malkoff M60 + 2x AW18500 = 140 minutes of continuously high output (9P/C3)
  Malkoff M60 + 1x AW18650/26 = 600 minutes of gradually declining output (6P/C2)
• Malkoff M60L + 2x AW18500 = 270 minutes of continuous medium output (9P/C3)
  Malkoff M60L + 1x AW18650/26 = 500 minutes of continuous medium output (6P/C2)
• Malkoff M60LL + 1x AW18650/26 = 900 minutes of continuous low (80L) output (9P/C3)
• Malkoff M60L + 1x AW17670 = 220 minutes of continuous medium output (6P/C2)

One thing to keep in mind for M30 vs M60 vs M61 is how voltage affects regulation.

The M60 on a single cells (low voltage) 'drops out' of regulation fairly early in the discharge process. This lowers output and boots runtime vs the M30 which keeps pulling the juice to keep up the output. Early tests show the M61 to behave more like the M30. Better for many situations, but less runtime overall (on single cells) than M60's.

EG,

Thanks for the runtimes.

You have the following entry listed twice:
Malkoff M60L + 1x AW18650/26 = 500 minutes of continuous medium output (6P/C2)

Is one suppposed to be for a different configuration?

Those L and LL models look like viable emergency lights providing that you have charged 18650's on hand. Are there big differences in output from the first 10 minutes to the last 10 minutes?

May have to pick up a LL or two, especially since they are on sale!

Thanks for the heads up!

Yes, the LL is the perfect emergency light. On top of everything else, it supports a huge array of batteries/voltages.

Thats the other cool part. The smaller the ma draw of a module, the better able more drained cells are able to provide it, even out of regulation. The last hour on an LL looks pretty close to the first hour.

Malkoff M60L + 1x AW18650/26 = 500 minutes of continuous medium output (6P/C2)

The M60 has almost 6x the run time of the M30 with 1x18650?

My M60 draws about .9A with a non-IMR 18650 cell, I get run times in the ~150 minute ballpark.

... I like your M60 better than mine:thumbsup:. I'm confused. Thanks for posting this information btw.

Any M60 runtimes with 2x18650's?
