RE: DNA200 - Low battery
TW summed it up pretty well. I'm not even gonna bother trying to get a replacement from FastTech, even if they had any kind of warranty on it (which I doubt seriously), it'd likely be far past that date, since I received it a few months ago and placed the order a few months before that. I've dealt with FastTech's customer "support" (and I can't air-quote hard enough on that) before and it's not worth the $20 I'd spend for a new LiPo.

RE: DNA200 - Low battery
Got a new LiPo, posted it in the "What did you get today?" thread but wanted to go into more detail here. 

So basically, it looks like the old LiPo swelled or was pushed in too hard, either way there's a puncture in the end that perfectly matches the spot where the 510 sticks out. I'll post a pic later. 

So I went to HobbyTown USA and asked the guy if he had something similar. He somehow knew instantly that it was for vaping, I guess he's seen this issue before. Anyway he showed me a couple options for 11.1v 3S LiPos that all seemed around the right size and I picked the one with the highest amp rating and capacity. 

Now here's where things get a little weird: I'm starting to seriously doubt the 1500mAh claim of the original battery. Looking at the LiPos in the store, the highest he had that was the right size was 1350mAh (which is the one I got). Then the only batteries with higher capacity were at least an inch longer, far too big to fit in the mod. So I'm seriously doubting the quality of that battery now. 

Anyway, what I walked out with was a 1350mAh 30C 3S that's almost exactly the same size as the "supposed" 1500mAh 40C that I pulled out of the mod. 

I just got home and stuff it into the mod to make sure it would fit, and it'll work just fine. I do need to trim the leads since it came with a 5-6" cable, and I'll have to solder the new connector onto it and use heat shrink to protect it. Fortunately the guy in the shop thought of that and I got a couple new connectors too. 

I'll be taking pics along the way while I do this, just to show off how it works. It's a lot of fun looking inside a mod for the first time, I'm sure some other curious folks might want to see the guts. And if I'm able to pull it off with my mediocre (at best) soldering skills, maybe it'll help someone else out if they have a similar issue.

RE: DNA200 - Low battery
Update: I've got the lead cables cut and the new connector put on, even with my really awful soldering it looks nice once I put the shrink wrap over it Tongue 

Unfortunately, while I was soldering I accidentally bumped one of the thinner wires on the other side (where there are four thin wires and a different connector that goes to the chip). So the soldering iron burned a hole in the rubber, so I gotta find some electrical tape to patch that up. But I tested the leads with a multimeter and it's working fine, so it looks like I got the new connector on successfully!

RE: DNA200 - Low battery
Plugged it in, and it seems to be working just fine! It was a pain in the ass to cram everything back inside the mod, they really didn't leave much (any) wiggle room and the battery is pressed right up against the 510... This one looks like a much better battery than the old one though, and I really doubt the 510 could puncture it since it isn't really sharp, just kind of sticks out a bit where the wire is soldered to the center post. But I've got it plugged into my computer to charge, and eScribe shows everything working just fine! I'm so pumped that I was able to do this myself. I'll post a few pics with descriptions of what I did as I went through the process. 

Damn, I feel manly after that.

RE: DNA200 - Low battery
Haha thanks mate. I want to make a joke about cubing a lot since that's the only thing I'll have to do with my hands tonight, but I feel like that joke might take it just a bit too far.

RE: DNA200 - Low battery
Alright, here's the promised pics.

First, the original battery with a hole in it.

Here's the original next to the new one I bought.
[Image: IMG_20161020_191656_zpsa9pkxmn3.jpg]

All the new stuff. I had the store recycle my old battery, and when I asked about the polarity of the connection the guy just cut off the old connector and let me keep it for reference. 
[Image: IMG_20161020_191739_zpsuf03uzvo.jpg]

As you can see here, the battery fits perfectly in the mod but it obviously won't fit with all that wire. Time to do some cutting and soldering!
[Image: IMG_20161020_191817_zpsynwcbu0j.jpg]

Pro tip from the LiPo store guy: only cut and solder the cords one at a time. That way you don't risk touching the ends and shorting it out. Pretty smart if you ask me, I certainly wouldn't have thought of that.

One down, one more to go!
[Image: IMG_20161020_191945_zpsykwveqqf.jpg]

And now both done! After connecting the first one, I checked it with a multimeter (touching the new connector on the red side and the old connector on the black side) to make sure it was connected properly. Same thing after connecting the black one. Also, the heat from the soldering iron was perfect for the heat shrink, didn't have to use a hair dryer or heat gun Tongue

DEADPOOL LIVES AGAIN!!!!!
[Image: IMG_20161020_192027_zpscmu4hzbk.jpg]

I'd just like to say, it was a HUGE pain to solder the cables that short. I'm not that great at soldering on the best of days, and when I rewired guitars I had plenty of room to work with. Not so much when the cable is half an inch long. The heat shrink on the red one actually halfway shrunk from the heat of soldering, so I had to cut the shrunk half off so I could slide it up over the connection. I cut a bit off the black one first so it went much more smoothly. I'm an idiot and don't have heat-proof gloves, so I burned myself once or twice. TOTALLY F#$%ING WORTH IT!!!

RE: DNA200 - Low battery
Nice job!

Keep us posted on the battery life, is it actually the same capacity as the old one I wonder??

RE: DNA200 - Low battery
Yeah we'll find out! It's 1350mAh and I'd expect them to be selling for real stuff (I've bought some other stuff from that store before and they seem to be on the level), and it feels heavier/better than the supposed 1500mAh one I pulled out of the mod. Also it's taking longer to charge, which to me seems like a good thing.
