Thanks Guys;

Monadnock, how did the Sanyo 18650's work in your JetLaser PL-C 250 green ?

They should have given you a little more power.

How much for two Sanyo 18650 cells shipped to Lebanon? Do you accept google checkout?

Thanks!

Well I got mine, and compared to the AW 2900mAh. They are performing horribly. I get no more than 1 min of runtime out of them fully charged. With the AW, I get over 6 minutes...

I dont believe these are true 2600mAh, actually, far below.

Has anyone else ran into this?

What are you trying to run them in?

The only thing I can think of is you are saying that it is only running for 1 minute before the driver's thermal protection kicks in not time between recharging.

Mine performed very well, and I have the AW 2900mhA too.

Cheers

These cells are amazing Ive had them for around 2 months now and still working Great. I have the AW2600mah as well and they perform the exact same if not the Sanyo's slightly a little better.

I also dont think Sanyo would make a cell that is crappy especially when there is thousands of laptops all over the world Using them.

I would also like to know what your are running them at.?

LarryDFW

I am running them in my DIY SS18650 host at 1.1A in a Microboost. For some reason my pot went higher.

I am going outside to do tests

Here is what happened.

Fresh:
AW 4.18
This 4.15

Used:
AW Went for 11 min and was 4.07V no flashing
This went for 56 seconds and flashed and was at 4.15V

It does this fast weird flashing, not like the slowly getting faster flashes I get from draining an AW cell. What is different about these batteries?

You could be having a connection issue. The Sanyo should be a little shorter than the AW due to the lack of a protection circuit. Can you tell if it is loose at all in the host when the tailcap is screwed down? I use the Sanyo 2600mAh batteries and can run a dual flex unit @ 1.8A for 10 minutes without any problems.

Toaster;

That behavior is very strange for new LG 2600mah cells.

Especially since the voltage is at 4.15 VDC at the end of the test period.

This voltage indicates 90% of the battery capacity is still unused.

That would indicate a driver issue.

If you don't get better results, return them, and I will exchange them for Sanyo cells, or refund your payment (whichever you choose).

LarryDFW

Alright... I trust that they work as I have read wonderful reviews but mine just dont seem to. I realized they were unused as the voltage didnt move.. Hmm.Ill try operating the laser in different orientations.

What I dont get is why is has the 1 min run times before.

I made a new thread to get it out of the sales

Here Please Help Diagnose This Battery Problem!!

Toaster;

After a quick search, it appears that a few others have seen the Microboost also do this with "charged batteries":

At 4 Volts the microboost should NOT be strobing.

Many 18650 cells will drop from 4.15 to 4.00 VDC with several amps of discharge current.

Another microboost w/ AW 2600 battery:
I think the wrong component is getting the blame for the strobing.

LarryDFW

P.S. The microboost manual also states:
A good rule of thumb to follow for input/output conversion is:
(Vout (Volts) * Iout (Amps) ) / Vin (Volts) < 1.2
Toaster Input - 5.5 x 1.2 /4 = 1.65 = Over Max Design Spec

I just finished testing my 2 18650's, and they lase quite a bit longer (more than double!!!) than my trustfire battery's.

I highly reccomend these to anyone who wants longer run times on their laser.

AAlasers;

The "low internal resistance" Sanyo 2600mah cells are the best choice for the Flexdrive.

I don't know if the Flexdrive will output 1.5A at the voltage the 445nm diode requires.

I have run one @ 1 amp.

Dr Lava rule of thumb to follow for input/output conversion is:
[Vout (Volts) * Iout (Amps)] / Vin (Volts) < 1.2
Your Design: [5V x 1.5A] /4V = 1.875 = Over Max Design Spec

LarryDFW

The "low internal resistance" Sanyo 2600mah cells will deliver 1Amp with the Flexdrive.

The Flexdrive is maxed out @ 1A at the voltage the 445nm diode requires.

Dr Lava rule of thumb to follow for input/output conversion is:
[Vout (Volts) * Iout (Amps)] / Vin (Volts) < 1.2
Max Current Design: [4.9V x 1A] /4V = 1.22

I just ordered a sanyo cell, that should be fine for my 12x using a microboost at 500mA correct?

My order for 2 Sanyo cells was in yesterday

i got mine within 72 hours of order, awesome guy, fast @$$ shiping, awesome batteries, good prices

what more can i say?

I got two of the Sanyo cells and the charger in the mail only a few days after ordering. I bought these after reading their good reviews on the forum. Unfortunately I can't test them against any other batteries until my o-like 400mw bluray arrives. From what i can tell they are quality batteries with a nice compact charger.

Yea these batteries are great. I prefer them over AW batteries actually.

I bought 4 batteries and they all rock !! Much thanks Larry. Im sure ill be back for more =)

Hi i want to buy 2 fo the sanyo and a charger. I have pmed you but you didn't answered. Do you sell these any more ????

Yes he does, you must be patient and wait. Not everybody on the forums is on the internet all day every day, some people have jobs and other hobbies. This hobby requires a steady hand and a ton of patience!

Yes, I am still offering the Sanyo/Panasonic cells. I should catch all PM's by the next day.

Panasonic has bought Sanyo, so they are the same company now.
