18650 battery

Yes charge away. Any 3.6/3.7 lithium cell is fine. They charge up to 4.2 volt. Cells are rated by nominal voltage.

I see one of the “tips” in the SV2 Rocket manual is to manually reduce the charge rate from 2A to 0.50A when the battery is “almost full”. I suppose this gives a more accurate termination point?

hmmm now where is my manual

Is this the vent holes you’re asking about…? There are 2 of them on opposite sides.

um I found it but it ain’t no good to me as it’s all in Chinese :rage:

Reading the translation is half the fun of getting new Chinese product! The instructions don’t say you have to reduce the charge rate, it is automatic, but reducing it is a “tip”. Otherwise the instructions seem common to other charging practices. I’m pretty new to this and needed a faster charger for the 26650s in a couple of new lights I bought and I found the SV2 on sale. :money_mouth_face:

I figured there was something going any was as it gets to 99% and then takes ages to finish

They’re all the same, made in the same factory. Sanyo has been a subsidiary of Panasonic since 2009. Sometimes they put Panasonic logo on the product and sometimes they put Sanyo logo, but it’s essentially the same product beneath the label.

:+1: Those are the ones! It doesn’t mean that the cell has internal protection, but a lack of them would indicate that it does not.

If you are using these in a light that draws 3 amps or more, you will certainly benefit from a better cell such as panasonic sanyo samsung sony lg.
Better meaning higher voltage under load, higher capacity, higher amp capability, lower internal resistance, resulting in more lumens.

SANYO NCR18650GA 3.7V 3500mAh ……….?

ok my sanyo cells rolled up today and I must say they look very plane jane

now I know this don’t mean much but all the have is a white sticker on them

and one of them small square things that you read with your phone .

so does this sound right or are they knock offs .

cheers D

Where are you buying batteries from deye?

these two sellers …… on the sanyo add you can see the QR code on the cell

Can you post a picture?

wish I could I have tried to use PB and another hosting sight and the pic will not display

EDIT it did take 3 hours and 15 minutes to charge them both today and they were within

2% of each other all the way to charged so I suppose they can’t be that bad .

and if you want a look here they are the same as these right down to the QR code

If you were around the corner I could test it for you. Thats not much help to you now though. It sounds like you have nailed it down that they are legit anyway.

yes this morning I did a test with my C8 and a cooling fan and got 1:40 at HI and I

tested the light at 2.9A (just a cheap DMM) so yes I think they are the goods .

and the best bit it looks like I found a source of them for $4 ea but I am now waiting

for a shipping quote .

cheers D

I can now (thanks to the members for help) even though I have cycaled these a few times through my l6

I know they have the capacity here is the pic anyway .

Yes those look real to me. Mine have the qr code and that blue ring.

On a side note havnt heard about and fake sanyo ga cells. Its usually your popular vaping cells that get faked. Hg2/vtc series/30q 30q is faked the least out of the bunch. Hg2 is very common

Stick with trusted sources. I know y’all get raped on cell prices down under. Look into getting a analyzing charger. Like a opus bt3100 or liitokala li500. Li500 can be had around 20 shipped usually. On either charger can do a charge/discharge function and get capacity of the batteries. Its accurate enough to tell if the cells are legit. There is a margin of error probably around 5% but comes in very handy. Can track the life of the cells especially once they get a couple hundred cycles on them. Or if you ever get into harvesting tool packs/laptop batteries.
Like now I’m going through 70batteties from the recycle bin. Out of 50 so far 12 are shorted out the others test right at original capacity. The real bummer is only 1300mah but 26 amp cells so. I have years worth of vaping cells now. And hurricane back up cells. On low modes will still last hours. Just not long on high and turbo. The smaller tool packs 18-24volt have the good higher capacity cells in them. The 40volt ryobi packs suck. I don’t know if I’d take them again out the bin. If I did I’d probably give the cells away to someone who needs them

yes I now know they are good as the convoy drags the amps out of them pretty good and the run times are

ok and the charge times telly good also it’s just at the time they arrived I didn’t know anything about them

and they just looked real plane Jane to me .

and as for reliable sources I just ordered 20 SAYO 3500mah GA cells from alibaba so I suppose I will see

if they are genuine or not soon enough fingers crossed , with shipping $8.00 a cell is better that $12.00 so

worth a gamble .

cheers D

Ya $8 a cell is better then 12 for sure. When you get a better charger maybe look in the recycle bins in your area. Sometimes old laptop packs and tool packs have plenty of useful life left in them. I’ve found a very large majority of lithium tool packs fail at the circuit board the cells are usually still very good
