Good that you are pleased with your setup.... lipos work well for me and USB charging a dna200 daily for almost 10 months now has not failed .... almost time to change the lipo out... I've used lipo's for years now and never had a usb charge port to fail (yet?)...
Sure are a few of USB jack failures on the forums. And I am not against lipos, I use them in many things including my RC gear. But for the life of me, I would never buy a device that requires surgery to swap the battery out. Man if I had to wait for my RC quad to charge up in between flights, because the lipo wasn't easily swapable... that would really suck. Same with vaping. At least vaping you can still use it if you can deal with being tethered. But it isn't healthy for batteries using them that way.

900mah is fine with me because i have about 30(not a typo) dna 200 devices so i just pick up another...
I'm jealous!

i had a question though. can i put ss tcr on any ss? or does it have to be some special ss wire?
There are different grades of SS. Like 304, 316, 316L, 317, 317L, 430, etc. And they use different TCR values. And even if you know the grade and recommended TCR, it doesn't mean it will be the best. As it also varies between manufactures.

Because during discharging, lithium cells gets warm internally. And charging warm internal lithium is like the second worse thing you can do to them. That is why many in the RC world allows the batteries to cool before charging. Otherwise their life shortens drastically.

the reuleaux is an exercise in good design imo. if jay-bo really exists he must be a design engineer. or someone there is. sure, it is not as small as my hana's. however the rounded triangle shape makes maximum usage of the space that is needed. ingenious indeed. considering it houses no less than three 18650's it is in fact quite small. fits in my jeans pocket but i wear baggies. still, it is by no means large considering the number of and type of batteries it houses. it is a great device overall too. lasts plenty long on 3000mah batteries. of course can hit 200 watts. the paint is solid. i got one tiny chip dropping it from my hand standing onto my concrete driveway. otherwise it is still flawless. not sure how long i have had it but a while. i said "it", that is a bit misleading because now i have three of them. i know a guy that is going to be making complete replacement cases out of stab wood and he said his target price is $150. i will let you guys know when he hits production but i am sure there will be a long waiting list. as it is one guy with one router. with that though you then have a seriously nice custom mod.

900mah is fine with me because i have about 30(not a typo) dna 200 devices so i just pick up another. i have all the way from 900 mah to the reuleaux . i think 1350mah is great though for most people. i do not remove batteries anymore so i think lipo's are fine now. before i did not feel this way. my rc charger can charge anything but i just charge them via usb now. i have a high end charger that can force 2amps to 1amp devices. if you want a link i can provide it but it is a very expensive usb charger. to me worth it. also, high end usb cables will not cause the jacks to fail but cheap ones certainly will. i am talking $50 usb cables. gotta pay to play!

i had a question though. can i put ss tcr on any ss? or does it have to be some special ss wire?
I agree about the Reuleaux, it's a great design (I have two rx200 and one DNA 200). Very effective use of space and very comfortable to hold. With my vaping style a 900 mAh lipo would never cut it, and I like replaceable batteries. I also prefer to save the usb port for upgrades only (and the option to fully switch off the mod by taking out the batteries is a plus).

Lithium batteries are widely used in electronics that charge while in use...

How did you do that? Moding required, or only changing the settings in escribe?
Yes you have to tell EScribe that you are using 2 cell, 7.4v, and the new watt hours. For wiring, no tools are needed. Just short the plus and minus contacts of the cell 3 bay. I used a 2 1/2" SS bolt as a test run and it works great. Using copper or brass would be better for a more permanent solution. Or you could always move the internal wiring.

Oh course, it is called convenience. It also isn't healthy to charge each cell up to 4.20v either. 4.10v is much better and they last almost twice as many recharges. But do they do this in most electronic devices? Nope. Because a slightly smaller battery capacity doesn't sell as well as a slightly larger one.

Thanks, I might have to try that. I don't really need three batteries at home, or 200w, and the Reuleaux DNA 200 stays at home anyway (I don't want lose it). Bay 3, is that the one farthest away from the 510?

i forgot something but i am not sure how this is going to be taken. please let's not argue,okay? i only watch pb if i want to see something new. never for his "opinions". opinions are like you know what....everyone has one. many things he said sucked i loved and vice versa. the main problem is the guy is probably in his mid fifties and he carries himself like a teenager imho. it was still cool in my very beginning of real mods to snap a pic with him. i can't deny the guy is a legend but not sure exactly why. i am not bashing him even though it sounds that way. i am just saying not my style of concise review. like for instance i would rather see wolf blitzer review these! so you can see where i am coming from personally. if you love him that is great. i have no problem with that. just not my style.

Using a bolt to pass voltage thru is not a good thing... if you want to convert it to 2 cell use you should mod the wiring.

Looking at it from the back, #1 is the back left, the middle one closest to you is #2, and the back right is #3.

Your mod's 510 connection is technically a nut and your atty's 510 is technically a bolt. So using a 510 isn't a good thing and you should wire it directly, right?

I don't trust him much, he's given out erroneous information too often and seems reluctant to admit it when people point out his mistakes (like using bad rewrapped batteries). Then again, that could be said about pretty much every reviewer. Almost. All of them seem to be clueless about things that an advanced, experienced vaper - particularly one publicly giving advice to others - should know.

As for opinions, apparently my derriere is magnificent, so therefore my opinions should be great as well, right? :)

Yeah, could be. I've used dummy batteries in some applications, but that was with AA batteries. Perhaps best not to try it with li-ions.

I guess all of those engineers who are using bolts for high current applications are just idiots and don't know what they are doing, right? Oh look at our rebuildable decks. They often use a bolt to carry 200 watts to our coil. How dare they!
