Review: Callie's Kustoms 18650 High Discharge battery

You sir, have big brass ones. LOL

But have you tried charging it back up and using it? :p

Now thats something Id like to see other battery suppliers try

"You sir, have big brass ones. LOL

But have you tried charging it back up and using it? "

LOL sorry I tried, the battery is Toast! its now reading .46v I tried 2 chargers. Both said connection break. I even tried the nimh setting to get it back up to chargeable condition. No luck but we can rest assured it lead a valiant life in the name of science

It is precisely coz of this characteristic that i'd love to gun them in DD triple XM-Ls for the Sanyo 2600. At $5 a piece, can't go wrong. The XTAR 2600 have very aggressive PCB protection but i suppose the discharge curve is similar. I can't get Rev Jim's Panny stuff, so these will do nicely. :D

intresting thread but at $29.41 AUD each shipped to oz puts me out

I saw you post on CPF , and yeah , upsetting the status quo !

There will always be someone .... But whats important , is the results .. And getting the info out there ..

you dont mean me

if so its funny how some peole on cpf thing its ok the parrallel charger batteries when the cells are discharging and charging them selfs from 2 to 6 amps + when connecting in parrallel and they think they are all corect and it will not harm or increase the internal resistance of the batteries over time, they make out like people who series balance charge are crazy,

I have less respect for CPFs "experts" than ever. I'm still an idiot when it comes to the whole thing, but that reads like a total backtrack. "Well no lithium cell is entirely safe..." Yeah... you wouldn't hear that if the cell said AW on the side.

Where is the data that shows parallel charging increases resistance? I’ve never seen anyone ever say balanced series charging is crazy… just charging in series without balancing.

to have alot of people and post saying parrallel is better then series and why do i bother then the so called proof connecting batteries in parrallel with diffrence in voltage in the cells, then to use graphs and test equipment to prove us wrong but the info show,s there is a sudden discarge/charge from 2 to 6 amps between cells, then to say there it is parrallel is better and theres the proof.

high charge rates will add resistance to the batteries over time the high the internal resistance the less the amount of charge/discharge per cell, this can be from age/use or how the batteries have been charged and will affect how much current the cell can give and in time will lower the end voltage and life of the battery.

a 2c to 3c (3 x capacity) charge rate is no good for these cells or most other,s and in my honest opinion will add to the internal resistance of the battery, even if they are hitting 1.5c to 3c + for short periods, like parralle connection for charging while the cells self balance.

i belive no one yet has done a pretty graph showing the increases of internal resistance of batteries due to there use,s and chargine connection methods, but over the years of using batteries from an rc back ground of some 20 years and playing with diffrent chargine methods (high & low c rates, multible, series and parrallel) with lixx for the last 7 odd years ive noticed it wil, the high the amp,s you charge a battery the shorter the life, the higher the resistance gets.

and for the record you can series charge any thing and most premade rc packs are made in series and most chargers and made for series charging, some rc (hobby chargers) will limet the charge time and mAh because they are not suit to charging muiltible packs in parrallel (lostly large mah lipo packs) and you can even series charge lixx in series with out balancing if your in a rush, but balance charge is recomended.

just my 2 cents and not worth more as its just my thoughts and my expernce.

now back on topic i would love to test these batteries from the first post i was going to buy 3 till i got to the international shipping page $29.41 AUD each shipped to oz puts me off at thats almost 90 bucks for 3.

i was going to buy some aw,s recomended on CPF at $18.50 usd each plus shipping but that to put me off, ive read some info on the aw,s true or false

no i was stuck been witch batteries to buy so i brought some tf flames from manafont

http://www.manafont.com/product_info.php/protected-trustfire-18650-37v-2400mah-rechargeable-batteries-flame-2pcsset-p-5560?rp=522815

i brought a couple to test out they took there claimed mAh rating they can take upto 5 amp draw and they are pretty consistance i brought more i now have 12 ive given some to my old man for a jet beam bc40 i gave him and a 2s (2 x 18650) balance charge lead i made and he is happy and 12 shipped was less then $120 aud.

im not say they are the best battery as they are not but for bang for buck if you get originals they are good, but is it worth paying the extra for these ? i mean two trust fire flames 2400mah at just under $11 each pair shipped at todays conversion or one Callie's Kustoms 3100 mah for $29.41 AUD each shipped to oz really worth the diffrence can the naked eye see the diffrence between 0.5 amp draw on high, i cant not on high.

at the price diffrence is it worth the extra claimed 700 mah as you could just buy more of the cheaper batteries to make up the mah, there has to be better more in the middle of the park if you get what i mean.

Hmmm , The Trustfire Flame 18650 no longer impresses me , as my much older Trustfire Grays now outperform them [ one of the first 18650 I ever purchased ]

I should do a Recap [ test older cells to see how they have aged ] , as I still have most of them .

Unfortunately here in Oz we need to source our cells from overseas , as local prices are far worse , I did try to buy Panasonic etc locally , and at the time the Panasonic 2900 was about $45 per cell from a local distributor ..

You could try contacting CK - and ask about shipping options and combined shipping . And whether you buy CK - AW - RL , the shipping will add to the price .

Ok, I would like to point out why international shipping is so much.

In order to use printed computer labels through paypal we must use priority mail. It costs us a minimum of $13.XX I simply do not have time to fill out customs forms and hand address every package we ship out to use the cheaper first class shipping.

I would also like to point out that paypal takes a bigger cut on international orders and we carry about 10 times more risk. So part of this extra money is basically insurance (for us) I'm not trying to open a debate or a discussion on this. If you choose not to buy from us because the shipping is too high I completely understand.

Thanks

I thought it only fair to "test" an AW IMR battery to see what would happen. I bought this battery about 3 weeks ago. Both batteries had about 4 charge/discharge cycles on them.

That IMR certainly did dump current almost instantly , The Panasonic appears to be far more stable ....

Wow I wonder what AMPs the AW IMR pulled ....

That was very interesting , thank you .

Voltage sag @ 1A CK VS my IMR ...

This review is showing on Google .... Wow ... Thats nice ! BLF reviews are showing up rather promptly ..

Yep, Google finally likes us. The .com domain definitely helps. As do excellent reviewers like yourself who constantly provide new, interesting content. Thanks a lot for these reviews!

https://budgetlightforum.com/t/-/2325#comment-64061 member mitro has done a nice High Amp comparison ...

I have tested the Callie's Kustoms 18650 High discharge battery in my Ultrafire TH-T60 (2 mode) The results are as follows:

Voltage Amps

CK 2250mAh 4.17 5.07

Sanyo 2600mAh 4.18 4.45

T/F Grey 2500mAh 4.10 2.65

T/F Grey 2500mAh 4.15 2.63

T/F Grey 2500mAh 4.05 2.16

T/F Grey 2500mAh* 4.16 3.04

AW 2200mAh 4.08 3.38

T/F red/black 4.10 3.23

T/F red/black 4.11 3.15

T/F red/black 4.08 3.02

T/F red/black 4.13 3.31

T/F red/black 4.09 3.31

T/F red/black 4.12 3.50



* This battery's PCB removed it was reading 0 volts

The Panasonic CGR18650CH is not an IMR cell. It is a hybrid Chemistry cell (like most modern cells are these days). It has Nickel, Manganese, and Cobalt in it. A true IMR cell (the M in IMR referring to the cathode material -- Manganese or Mn) will just have Manganese and will not have a hybrid cathode material.

Also another obvious way to tell it is not an IMR cell is the recommended voltage cutoff which is 3v. All other "IMR" cells usually have a 2.5v recommended cutoff.
