3X D Cell Li-ION being shipped to me now!!!

[Fitsbain]

They are unprotected but with the addition of a hotdriver they should be safe for an 85 or 116.

I'll get testing results up as soon as I can.

Max draw I can monitor capacity with is 3 A (due to origional triton limit).

Now I need a Hotdriver.





You paying attention man? Sent you an email about getting one but you never answered.

Then I just need a Socket and an 1164 bulb and I'm off to the races.

And don't forget a fire extinguisher for the average user who does not yet realize the fire danger of charging unprotected cells.

 

[DM51]

Fitsbain, I hope you and your family have very good medical insurance, because you are going to need it if you play around with dangerous things you clearly don't yet understand.

I suggest instead that you settle down and do some careful and thorough reading about Li-Ion technology.

 

[VidPro]

umm dont try and 1C charge a Dcell li-ion. i heard from a good source it makes for a really cozy fire

 

[Fitsbain]

Don't a worry. Be happy!!

I know the dangers.

Will be using a triton smart charger that has been doing service charging my li-poly unprotected rc flight packs for 2 years now. Those burst even easier than ION's as they can be physically damaged due to only mild miss handling.

I know that everyone wants protected cells so I'm not sure if there will be much of a market for these, But I am getting them as samples for testing. I'll post the results here and then press them into service in my first hotwire.

Should be good for 1.5 hours of a 1164 bulb at 9.6V (1500 lumens)

But I need to reach Andrew and get one of his hot drivers (That will also serve as the low voltage cutoff).

 

[VidPro]

you gonna run an unprotected li-ion with a INCADESCENT bulb in series?
how will you know when one battery has reached its cutoff voltage?

 

[Fitsbain]

For a single run they should discharge at about the same rate. Andrews hot driver has a low voltage cutoff that will kill the light when they get down to a percentage of the starting drive voltage. Then a slow charge in series, or charged 1 at a time they will stay balanced.

Same thing the RC croud does with multi cell li-poly's.

Some of those guys run 4 and 5 s packs at upwards of 20C discharge rate and have no problems as long as you respect the batteries. Our RC pack are not protected, but the motor controller has a low voltage cutoff.

 

[VidPro]

nope, your not thinking carefully enough.
even RC people are multitapping series packs now, to rebalance them.

both sets of Dcells i have been using for years are nothing like a extreeme discharge recharge rate li-poly. they are more designed for long term runtime. and there is no recommendation to fast charge them, and they dont even want me to fully charge them (4.1V)

 

[Fitsbain]

But for non-multi taped packs a slow low C charge will ballance.

 

[VidPro]

But for non-multi taped packs a slow low C charge will ballance.

yes in a ni-mhy or ni-cd, but only that new safrion li-ion CLAIMS it can be safely done like that.

99% of li-ion batteries can NOT be balanced by a slow charge rate, in series.

and more importanatally you will pop them open. IF they are properly Mechanically protected, you will get an anode disconnect, and lose your battery :-(

Speaking of Andrew (AWR), he set me up (I'm now realizing I'm no longer comfortable with it) with a hot driver that shuts off when voltage falls to 11.58V (2.9V/cell) for a 1D Mag66 using 4x14500 UNPROTECTED Li-Ion cells. I could not use protected cells because they didn't put out enough current to get past his Hot Driver threshold...thread here.

I have taken this light out of service as of yesterday...so I'm putting my money where my mouth is.

I have also moved my charging from the family dining room wood table to the concrete floor of the garage, with nothing flammable in it.

Is there a way to safely tap these AW Li-Ion cells so I could hook up a cell balancing connection for my Hyperion 1210i charger + LBA-10 balancer.

 

[VidPro]

ya gotta ask yourself this.
why did all early laptop batteries all die a early death, because of the lack of proper balance/charge curcuitry.
why did they blow up, fast charge rates on an imbalanced pack.

why does my camera batteries 2x series 7.2v packs die an early death , even when there are battereis in the pack that have at least 80% of the original capacity.
No Balance.

well at the least, it HAS a cutoff.
Pull the battereis and charge them as soon as it DIMs, because cutoff is somewhat related to extinguished capacity.
seperate the cells for charging, and you re-balance them
before charging make sure that none are to low
if it went to low, watch it on the charger, does it get hot?

that is indeed the problem though, with HOTWIRE stuff, we need a much better protection curcuit, it needs to go to a REAL 10amps, and the ones i have tested peter out at above 4 :-(

 

[Fitsbain]

Since they will not be a pack, they can always be single charged to balance.

Also they are avalible in unprotected, and thermal/over current protected (Fuse).

Once poped the battery is dead, but it prevents high current meltdown.

I don't know if these will be right for many people here, but I'm getting them free for testing and will make a hotwire out of them.

Then I'll post the results and offer them for sale with the approprate warnings.

Just trying to help out the CPF communite with something that otherwise seems to be unobtanium. And if we get enough intrest I may be able to get the manufacturer to make better protected cells (ALA AW).

Yes, I am ONLY now going to individually charge Li-Ion cells, despite this setup with tailcap "convenient" serial charger plug. This was sold by FM as an AA light, but AWR converted it for me to the Mag66.

Is there a way to SAFELY "tap" the cells so I could use my Hyperion with balancer? I just don't know what is involved with tapping cells specifically...but they do it in the RC packs.

 

[VidPro]

they were unobtanium, then we HAD them available, then people had a fit about safety. not enough people knew how to apply them fully safely.
and some of them china battereis do not anode disconneect properly, and the anode wire is like a fuse alright a fuse leading into the lithium

isnt that designed to hold PROTECTED batteries?
protected batterys WILL cut off, and remain safe, you could just balance every once in a while.

OK, now here is some REAL information. After taking the four 14500 cells out of this holder which have only been charged with Alin's "Universal Lithium Charger" here are the Voltage readings:

Cell #1 - 3.95V
Cell #2 - 3.24V
Cell #3 - 3.89V
Cell #4 - 3.41V

​

No, in the original thread where I discussed this all with AWR, he made it clear that they needed to be UNPROTECTED cells....read here starting on page 2. You can see the level of battery noob I started out as...and which is typical of many Maglite users.

Eventually, I sent the entire light to him, and he sent it back with the hotdriver, 1166, and unprotected cells installed....see my post on page 3 #72 where he sent me this in email.

the ONLY reason i mentioned anything at all was because you have a fast charger, your getting cheap china batterys, and your using them on incadeescent without seperate battery protection.

I do Wish you great luck and much happiness, and i wish the dang things were used in every houshold in america, and sold on e-bay for 10$

i think that will happen if total proper use of them is applied , for both the long and short run.

but people have made the simplest of misteaks, and could have burned down 3/4mill doller homes if they had not been there.

ohh, well that is not proper.
MYSELF i would still use it, and now YOU SEE exactally what i have been trying to splain 100times .
you know what is going on, and now you smart enough to be able to deal with it appropriatly. at least you got a meter
