This is very nice discharge curves where the two batteries tracks at all currents and capacity do not drop much with current.

Your formatting is a little bit broken in the beginning of the post.

Looks like a great battery, although I’ve never heard of Molicel before.

Thanks for the review,,,been waiting for this one! Thumbs Up

These are GREAT cells. My Hometown dealer[Liinonwholesale.com] is the ONLY authorized USA dealer…0.9 miles away!

FRESH CELLS! A=2010 B= 2011 ECT,,, I919= I2018 919=September 19th……….yours are 2018 Sept. 18th!

You got 2533Mah @ 1Amp

My 4 Slot median is 2614mAh

P.S. MORE proof that the Apexium INR 18650 2600mah and the Vapcell INR 18650 2600mAh [Green] are using this cell as the voltage curves are basically identical for ALL Three cells.

Invigorating hike w/ CAPO this morning,,,Chill factor was Minus 17F/ Minus 27C!

@wolfdog, the tester used by HKJ is a constant current tester.

The tester you have uses a resistor based tester. Meaning current drops as the voltage drops, and therefore, the capacity is overestimated.

Yep, all Opus chargers read a little high on a discharge test, I know mine does. No big deal as long as that fact is recognized & accounted for.

I’ve got one molicel P26 ,had it for about a week ,on my skyrc mc3000 the IR is 17 ,& after first use ( after a full charge ) from just over 3 volts it put just over 2600 mah in when charged @ 1amp , I havnt done a discharge test yet.

Thanks,,,I know that. My Opus is usually 3% to 5% higher than HKJ.Although I have had some numbers in the last few years that were less than 0.1% higher. Wink

In this case my numbers are 3.1% higher. Big Smile

I think the opus is about right & here’s why , firstly it undercharges ( unless the solder bridge has been desolderd ) secondly it over estimates , so therefor one cancels the other out & it’s more or less on the money.

The people buying this cell are going to care more about the high drain performance rather than the total capacity. I guess it appears to be right in line with the VTC5A. Is it better? VTC5D is probably better but at a much higher cost

I use it in my TN42vn90. Get 25 minutes of max output w/ voltage @ 3.54V. I have 2 carriers[8 total batteries] ,,,,,,,,,,just swap the carriers instead of messing with the batteries.

Another testers opinion: NO mention of the VTC5D,,although he tested that battery.

Bottom Line
This appears to be the cell that was rewrapped for the green Vapcell 25A 2600mAh and Ampking 35A-45A 2600mAh cells. It is a great performer that beats the Sony VTC5A, equals the Samsung 25S, and almost equals the Samsung 24S or Sony VTC6A.
