New 18650 at my B&M

I doubt the B&M owner friend will pay for the medical bills if something goes wrong. I wouldn't trust anyone to "have my back" when it comes to medical bills, especially a guy at a store that's selling me something, even if I considered him a friend.

Very true. I always wondered what people meant when they say their (whoever) has their back should an accident occur. Are they going to pay for the medical bills and the loss in pay while you recover? I think not.

I personally would not touch them with a ten foot pole, and I still own an Efest

OP, please... you're talking the equivalent of wingsuiting through a stone arch.

First... our RXs are some para-series setup. I have no idea how the amp draw is distributed in such an arraignment, but you've already said you're looking to bang 'em at 150w. Not logical.

Second... you're hunting Unicorns. Our best known 3000 mAh cells are 20A CDR. You're pinning your hopes (and hand, and face) on some upstart stumbling upon a better formula of the very well known chemistry, and teasing out another 5A.
And they aren't crowing about it all over the Net? Not logical.

Last... @Mooch, I've seen you comment exactly once on the "B and C Bin" topic.
I'd love to hear your current thoughts, but assuming they haven't changed... would you please repeat your comment here?

They might have changed, I don't know what comment you're referring to.
You can always copy&paste it here.

Just a side note...the RX200 is a series battery device. If that's the device you're talking about.

On the RX... I'm not positive they're all in series.
Someone who's opened theirs up and looked over the wiring could confirm it.

On your comment... it was a while ago now, and I'll have to paraphrase a bit..
Essentially, you said you had not seen any evidence of the "seconds bin" practice.
Something along the lines of "potential urban myth" may have been mentioned.

Um, it's a regulated device with the batteries wired in series. There's no doubt about it.

 

[Mooch]

The RX200 is absolutely a 3S device, all three batteries in series.

I'm just not familiar with the different practices of using lower grade cells by battery companies. It might be done by most, most of the time. It just be done by a few, some of the time. I don't know if anyone knows. We can make educated guesses but unless we see their invoices it's only guessing as to what is bought when. They could be top grade cells one month and total garbage the next.

I don't remember mentioning anything about that possibly being a myth though. We just can't be sure of what grade we're getting from any company at any time.

 

[Jim_ MDP]

Cool beans then, thanks both of you.

I still wouldn't like to test some unknown newcomer's batteries at 150w.
Not even with three of them.

And I've risked life and limb in some crazy ways.

 

[EverPresentNoob]

Not that its being debated, But i have had my RX apart completely. definately a 3s setup. No questions about it. Pos from the sled comes from the bottom right batt to the board, neg is from the top left to the board. its the screw behind the little foam plug that some have had to tighten.

 

[TheMike21]

Correct me if I'm wrong but when in series, If your output is 20A is it split evenly throughout the 2 or 3 batteries? Do they share the load? So if I have 2 20A batteries my limit is now 40A?

No, 20A in a series mod means 20A through each battery.

Mmmmm... Not good. So how are we reaching higher and higher watts without blowing up? Cause a .05 nickle build at 150w is 54.77A What battery stands that? where am I wrong?

have a look at "step down transformer"

In a series you have more voltage available. The higher voltage/lower amps at the battery is converted into lower voltage/higher amps by the regulator.

I glad there are so many post about battery saftey here and I have learned a lot of valuable things here. That's why I stick with my LG HG2"s and the 25r's. I have had no problem with any of them and would not try a 40 amp battery.

 

[EverPresentNoob]

I would LOVE to try a 40 amp batt... When real one is made that is.

Well after some time and charge cycles with the listmans all i can really say is there ok they discharge at around the same rate as my brownies take about the same time to charge and at heavy use at 60 to 120 watts they don't really get warm but since there are re-wraps maybe i got the good set i still would not recommend for mech or unreg. mods to many unknowns and this is just a normal users words i am in no way a expert in batteries and i did not try the listmans for the quoted 40amps i am just looking for the best battery life i can get the longer they can run the happier i am but once again i'm disappointed cause they don't last any longer or any shorter then my brownies so i guess i'm back to hunting down the next best thing.

The LG hg2 (and Samsung 30q) are the best thing for battery runtime in a reasonably high drain package. A rewrap certainly can't beat it. How could it?
