Hmmm..losing power?

[EMatic550]

So I've got a trustfire 18650 2400mah 3.7 batt to power my maxi rs v2....I've got only 1 (2 more are on the way)
but I've noticed a drop in power when the battery is weak. I've also got a 900mah ego batt and I've never noticed a power dRop it would just blink and die. Thoughts? I've been using the ce3 smokyizer 2.5ohm.

Trustfire does that on some of the batteries....
aw batts seem to be better...

I think thats normal with a li-on battery. Same thing happens with mine. You can tell when its puttering out.

 

[EMatic550]

aw batts? I'm still new to the whole mod scene lol

AW is a brand of battery, generally very good quality too. An eGo battery is regulated to 3.2v so it maintains that voltage until it shuts down. Your Roughstack is unregulated so as the battery is used the voltage drops. They'll usually start out at 4.2v fresh off the charger and the protection circuit will cut off at around 3.2v or so. That's one of the drawbacks to an unregulated mod. The advantage is the 4.2v's you get starting out. I'd suggest you charge more often, but with only one battery that's a bit tough to do. Once you get your other batteries you'll be set.

What cskent said You beat me to it, but that is exactly the reason. And you probably explained it better than I could. heheh

An AW battery on an unregulated mod is def the way to go. It doesnt drop off as quickly and will be more constant than the Trustfires.

Also Id recommend not letting your batteries go all the way till they die. Id charge them when they get to about 25% left. Its better for the battery and will also make them last longer

 

[EMatic550]

Nice! Any respectable vendors that sell them at a good price? Like madvapes, etc?

 

[mynameisrob]

Im not sure if madvapes has the AWs.

Check out Super T manufacturing. They have a ton of AW High-Drains and AW IMR High-Drains. You should even be able to get the different ones from there so you can vape at different voltages. If your order is under I think its $36 bucks, shipping is only like $1.35 or something. Itrs really cheap. And they ship fast.

Look on Super T's website under the Photo Gallery tab. If you scroll to the bottom youll see what we were talking about with the High-Drain batteries not dropping off as fast. They have graphs that show what the AW batteries do. Instead of continuously declining through the whole charge like the batteries you have now do, The AW High-Drains stay pretty constant and only drop slightly through the whole charge all the way up till their almost dead and then drop off sharply.

If you look at the graph comparing a normal battery to the high-drain, youll understand why you notice the continuous drop/loss of power as you go through a charge. The AW batteries are more expensive, but are def worth it, especially on an unregulated PV like the RS.

Hope that helps!

Here's another good vendor for AW's .... AW Batteries

 

[dormouse]

All batteries come off the charger with higher voltage (like 4.2 for a 3.7v battery) then quickly drop to the start of their 3.7v plateay which degrades slowly and then a steeper dropoff near the end of charge.

AW IMR batteries hold the voltage plateau up better BUT have lower mah (a bit less charge). Try AW IMR and try to plan yoru battery swaps to avoid the steep voltage drop off near the end fo the charge.

Super T Manufacturing is a good place to buy batteries.

Thanks for the info guys! Another question though (i got some AW batts on the way as well)
If I was to stack 2 batteries 16340's 880mah 3v in my RS to get 6v, would it give me 1760mah?
Sorry to sound hella noob, lol!

 

[440BB]

I think it gives you 880mah at 6volts. If they were run in parallel you'd double the mah at 3 volts. There's a RS users thread here on ECF if you need or have more tips!

 

[mynameisrob]

Yeah 440426 is right. While that would be nice, unfortunately it will still be 880mah, but at 6v.

Also like dormouse said, don't let your High-drain batteries, or any of you batteries for that matter, run all the way till their dead. I dont know if you looked at the graph I told you to look at but if you do, what dormouse said about trying to avoid the steep drop off at the end, will make alot more sense.
Like I was telling you before, the high drains will not drop off as quickly throughout a full cycle. If you look at the graph, it only drops slightly as the battery drains but once it gets to the point that the battery is almost dead, it drops off very quickly.
So like dormouse said, try to avoid that. Try to switch to a new battery when the one your using gets to about 20-25% left.
If will make your batteries last longer and you avoid over discharging them which is bad not good for the battery. Doing that will also then avoid that steep drop off at the end as well
