New type of 18650's?

Was just looking around on eBay and noticed my battery seller is stocking these.
Have I been living under a rock and have missed these? They look like BD’s with higher capacity, would this be a fair comparison?

Interesting, but the dollars to mah ratio is out of my league…

FT have the Sanyo version which I assume is genuine.

Very nice, I was looking for something for the M43 that I’ll eventually buy and it’ll probably be these guys, highest capacity and high discharge rate

I figure if I buy good torches it’d be crazy to use cheap batteries. That’s how I justify it to the missus anyway :wink:

Gday Lionheart, good find, i have not seen these before either, the fasttech sanyos work out to be $21 australian[plus tracking ] and 2 weeks delivery anyway.[fasttech is where i mostly buy my cells]
I also noticed on the aus site you linked[thanks] they have most of the latest cells, some pretty reasonable like 4 x LGMH1,s for $38.90 delivered - i dont mind paying a little extra if i can get it pronto and like you say quality cells are must specially for that M43 badboy.

These are the new gen 18650s, Sanyo GA, LG MJ1 and Samsung 35E. They have great specs but I would wait for HKJ’s or other accurate review first. As of now the best of the 3 is the LG with a discharge rate of 10A.

I’ve purchased from that seller alot, he is a good dude. I normally buy NCRB Blazars from him, but for high drains I’m thinking of giving these a go. I hope HKJ does a review of them soon.

I’ve never used Sanyo batteries before, are they comparable to the Panasonic’s? 10A discharge rate will cover mostly everything in our expensive little hobby.

Panasonic owns sanyo but they still use both brands. Sanyo cells are generally very good, all of my sanyo red 2600mAh bought 4 years ago are still working great, those are legendary batteries.

I used to own dozens of panasonic NCR18650B and BD but sold them because their low discharge rate can’t keep up with my DD lights.

Actually I sold most of my 18650s as I wait for the new cells. All I have left now are a couple of Samsung 25R and LG E1.

3.5Ah you say? Lets see what HKJ says when he reviews them :D!

Little side not - ThinkPad batteries with Sanyo cells used to be the worst of the bunch, losing capacity with each cycle and crapping out after few hundreds, while Panasonic ones used to work for 300+ cycles without losing much of their capacity!

Go figure.

The seller does all the same testing on his batteries that HKJ does, he just doesn’t review them (he is an electrical engineer)
If he says 3500mah, they are, no doubt.

Is that correct, 3495mAh at 5A and at 10A?!

If so, very impressive!

This battery is competed for LG MJ1 3500mah.But ,it seems the LG MJ1 with better performance .I have seen a comparation of them from somewhere

Would love to see that comparison if you can find it

I can’t find it now .As I remember the result is :The LG MJ1 will give more capacity at 0.5C/1C,etc .The SANYO GA better capacity at their max discharge current (10A)

I seriously doubt that at 5A these batteries will have 3500mAh. What current did he test them with? And to what V limit? 2.5V ? 2.8V ?

No idea, but I’ve seen his testing room, it’s full of stuff I don’t understand lol…
There’s some graphs in the OP’s link.

I took a look at those graphs, and the battery does get very, very close to 3500mAh at both 5A and 10A current draw, if you are willing to take the battery down to 2.4V. Capacity will be around 3250mAh if you stop at a more realistic 2.8V. Still impressive.

Holy Moly…that guy needs to work on his ad formatting.

I think I just had a mini-seizure trying to read that thing.

If his testing is accurate, they’re killer cells if they yield a decent lifespan.

We seem to be in the midst of a bit of a small generation step.

I would be really interested to see new LG 4.35V products. So far I am attracted to the LG E1. The thing I like about it the most is the way the voltage holds up. For unregulated lights, it will keep the light output more stable and for longer than the other batteries. For regulated lights, it will keep the current in the control chip lower than other batteries. Lower current means less heat dissipated in the controller. Can't hurt.

Given the prices I am seeing for new iteration protected cells, I am not sure I want to get into the better (either the LG or the 3500mAh GAs) batteries right now. My plan was a set of 12 now to keep in the emergency light and 12 more for backup. Looking more towards just 12 and see how prices work themselves out to buy 12 more.

Looking forward to more info on this forum.
