REO Grand battery: 2900mah high drain?!

[Rictic]

This just might make me take the kick out of my REO and try my Grand 18650 mech style once again. 2900mah and impressive chart data, showing some better sustained output over time. Just saw it here ORBTRONIC PD18650 2900mAh HIGH DRAIN

I don't see why not...

Mine too....

I run a 3100 mah orbrtronic protected battery in my grand. Sucker is a beast, I love those batteries! They are a tad longer than aw's, in other words don't pick them up thinking you can run them in another 18650 mod. They may or may not fit. More than likely they won't, but they fit great in my grand!


Oh and the link also goes to the ecf homepage for me also.

You must be careful that the spring is not compressed down too much with those batteries. You want the spring to collapse in case of a short. The collapse allows the battery to drop away from the positive contact. http://www.e-cigarette-forum.com/forum/reos-mods/278766-reo-spring-how-far-will-you-go.html#post5589690

Thanks, I am pretty ignorant about batteries, but I have to wonder since I am using protected batteries would it not have the safety already built in? The increase in height is due to the protection feature nothing about the mah of the battery.

These are the recommended batteries: AW IMR 18650 1600 mAh

The IMR batteries will work better in the REO's. Especially if you are running lower ohms.

The price is good and with ECF5 you get an extra 5% off.

Thank you for that link. Though now I am still curious if the dual protection in the ones from orbtronic would still prevent problems in case of a short? I have many many many 18650 batteries, and have used rtdvapor many times, but now I would love to know if your battery is actually protected instead of just "safe chemistry" if the spring would still collapse in case of a short? My thought here is if there is an over current protection inside the battery that it would prevent the short even triggering the collapsed spring. Therefore save money in the long run cause you wouldn't have to send your precious back to rob and you wouldn't have to buy as many replacement springs if a short did occur.

Just curious! I plan to continue to use these batteries. I have been using them since I first got the grand last year, I purchased them specifically for this mod, and they have a great amp rating which most protected batteries do not, which allows me to use my lower ohm coils.

What Karen is trying to say is having some spring room in a mod is more important . Protection circuits in batteries fail I have seen this many times . Your spring on the other hand will not fail to do its job . If you have a short the spring will drop and break the connection . I always recommend using aw imr batteries

Problem with protected batteries is that the protection circuit adds 3-5mm in length. 3mm will compress the coil too much, 5mm won't fit at all. Compressing the coil removes the Reo's built-in protection, which is a lot more reliable than the battery's built-in protection. You do get higher capacity out of protected batteries due to their chemistry, but the IMR ones are safer.

Also, IMR batteries generally have more even discharge curve. What that means is that while protected battery will take longer to run down to 3.5v, an IMR will last longer to 4.0v, providing you with a usefully even vape longer.

IMR batteries are considered safe (and have no protection) because they don't go catastrophic when hard shorted. Magnesium isn't quite the powerhouse that Cobalt is (ICR); but it doesn't go Ape-shizit when drained at a rate that results in imbalance/freefall. They get very hot. (like 250 F.) This would collapse the spring (I imagine). What has happened to me, in other mods, is I instantly noticed upon pressing the button, that things were getting real warm, real fast. So, I almost immediately released the button. Tried a few things (including a few more quick button presses), and figured out that the atomizer had a short. No harm, no foul.


. . . . . . . . .↓ This is speculation, and musing ↓ . . . . . . . . . . .

I think part of the value of IMR is also in SLR vaping, where you don't want to be tripping the protection. If, say, the protection is based on the maximum continuous discharge rating, and you are pulsing (5-10 sec. pulses) at or above that level and tripping the protection. (Max pulse discharge of the IMR/unprotected batteries I've looked at is substantially higher than continuous)

I learned my lesson on batteries, I will only use AW IMRs but the 1600 mAh batteries were as long as my Panasonic.

Sorry about the link guys. Can't get it to work. It's on tasteyourjuice.com
It is an 18650 High Drain battery, which I'm guessing should mean it's the same size as an AW 18650. But while it does say high drain, it doesn't say IMR; I don't know what difference that makes (would like to). Rob recommends the proven reliability and consistency of the AW IMR 18650 on the Grand. But if I can bump up the time I stay at 4+ volts of charge I might try this out and try going to back to full mechanical. I'll even pay more attention to making my RM2 coils a more consistent 2.0 ohms, which the reason I got a kick in the first place was to make up for the inconsistency in resistance I prevail at when making my RBA coils.

Edit: I got link to work for the site that sells them.

 

[pdib]

Yep. So, if you look at the chart @ tasteyourjuice.com, and you're vaping mechanical, then you only need bother with the first section of the graph. I swap batteries at 3.8V or so. AW 2000mAh outperforms during that critical phase. Also, with 24 Amp max. continuous discharge, the AW 1600mAh battery swats the AW 2000mAh neatly out of the park. For those of use regulating our vape (kick or VV), its a whole 'nuther story. But with Mechanical (SLR to boot) I'm looking at low internal resistance on the battery, and one that can handle a higher discharge rate is indicative of that.

[unsure]

Size for any REO....always safe!

 

[Freckle]

Rob in other words if the protection circuit in the battery works it won`t trigger the safety spring? though if the protection circuit has gone bad for whatever reason then the spring is a safety net?


think I understood that correctly.


so what causes a protection circuit to go bad in a battery?

Here is a good site to gain information on batteries: Battery Information Table of Contents, Basic to Advanced

[Ratman]

Really in a REO or any mechanical. IGNORE mah ratings. They are completely useless and misleading. Much of the mah in the high capacity batteries comes well below 3.5v which is unusable mah and wasted. It is very hard to beat the good old AW IMR 1600mah battery for all aspects of vaping on REO.

 

[ltrainer]

A concern also arises if static electricity or a faulty charger has destroyed the battery’s protection circuit. This can fuse the solid-state switches into a permanent ON position without the user’s knowledge. A battery with a faulty protection circuit may function normally but fail to provide the required safety.
