ill have to give that a try on the weekend as i have sealed my unit of w/ silicon and don't feel like going through the bother till then

Methods and I both have over 1,000 of these moli-cel 26700 LiMn cells in new condition that do test over 2.5Ah. I personally don't sell things like that, only give it away to folks who do things that impress me.

Methods sells his I believe though.

Woah, four screen work station?
New to endless-sphere? Notice a lot of signatures recommending Ebike.ca? That's because it's the best place for a quality and manageable, (but still 'real'), first build. Justin is a solid supporter of electric bike development, and a good source of equipment.

My hat off a thousand times to the green people that effectively run this forum. The ES Mods are superb.

Alright,

Test Cell 3 and 4 choosen very randomly scored a high 2.09 and 2.15Ah at 1C.

Is it possible that at like 7C the battery can't just take it?

The test went on for only like 2 seconds??

7C is 20.3A per cell, right?

That's only half of the maximum 40A claimed rate. Disappointing for sure but not totally surprising considering the common practice of over advertising. So do you plan to continue testing at lower rate? 5C, 4C...

I wonder if people who bought HK super duper high discharge RC Lipo batteries (50-100C) have ever actually done any testing at all.

Edit: I just went back to look at the discharge graph in the data sheet you provided:

They did have discharge data at 20A (red) and 30A (black), and the capacity is only about 15% less than 3A discharge. So it looks like you have problem with the test equipment.

Emoli cells are good to about 3C in the real world. If you want high discharge then buy Lipo.

Anyone wants these Emolis? They are mostly between 1.6 to 2.5Ah.

Tested a bunch and I am pretty dissapointed.

Make an offer for the cells bare and if you want, make an offer with the Milwaukee packs still assembled.

I believe they make high end rotary tools like drills and stuff, and probably some are cordless.

I got them from Milwaukee V18/V28 battery packs, but Hilti is Hilti and Milwaukee is Milwaukee, what I did not understand is why he was "out" because he had a Hilti shop close to him.
