Figured out why I was consistently arcing on batteries

[camerajunkie]

I have 1 LP Reo Grand that Rob modded for me. For the longest time, no matter what I did I was arcing pretty gnarly and even on some higher resistance builds like 0.7Ω. The issue was with my delrin cover, since I used to over-tighten, I started to not tighten enough and had a 1~2mm gap from the bottom lip of where it meets edge-to-edge with the delrin.

I figured this out because a set of 4 25R Samsung's came in and I couldn't get them to fire for the life of me. I noticed that I wasn't making contact as easily. I looked at the other silver finish Reo I had and noticed the delrin sitting flush on that edge-to-edge point. I adjusted and tightened a bit more and all those misfiring issues I had which boiled the BeCo of another positive contact went away.

If I hadn't picked up a set of flat-tops I think I would have never noticed this issue. I just thought that the delrin was supposed to sit the way it was sitting.

About to adjust the 510 and try the RM8, the RM8 was giving me the most problems because I had a 0.27Ω build on it when I started having this problem 2 weeks ago.

Thought I would share.

Interesting. Are you talking about the gap arrowed in the picture below? All of my Reos have a bit of a gap there. I do not get much arcing, but then I apply deoxit regularly.

I had the gap all the way across, so it was slightly pushing down on the battery. AW IMR's would run fine, but from time-to-time on lower resistance builds than 0.45Ω I would see arcing. It got better when I bought some replacements from Rob, but it was still arcing. I'll see what's up with the Samsung's, but Super_X just made a video where he's seen flat tops arcing moreso than AW's.

Thanks for sharing what you found, for every person that finds such an issue's cause, there's probably 10 folks having the same issue that can't figure it out.

(The highlighted portion in your quote made me smile. I vape at 1.6 ohms and don't consider anything below 2.0 "higher resistance" )

Your welcome, i only rock these numbers on the LP. For daily I've been rocking a silver reo grand with stock 510 from 3 yrs ago.

This mod has been passed around. Buddy 1 bought it 03/12, couldn't get off the analogs. He sold it to buddy 2 about a year later. Buddy 2 has 3 reo grands and 1 vv turned mechanical, so it was mostly a shelf mod. Buddy 2 sold it back to buddy 1, buddy 1 liked the new rm3 over boge atomizers, but wanted "cloudz for dayz." So he bought an ipv3 li. I walked by his desk at work and asked him what he was gonna do with his reo. He was like "I dunno sell it." I was like, "how much?" He says "$30." I says "shut up and take my money NAO!!!!!!!"

So my daily is a pristine silver grand that runs 0.5~1.2ohms with only an rm3. Recently building it at 0.45 with bored out air holes I've noticed it makes some kicking .... vape.

Love having 2 functioning reos. For 3 years I only had 1 and only 1 mod. A reo grand that is now the one I fixed and is vaping sweet nastiness!!!

Nice thread, cj. I had not heard of this particular issue arising. Glad you got it sorted and it's now another tip/trick to add to the vault.

I don't have a gap like in the picture above. I don't see arcing on my Reo Grand LP. I wonder if I have mine set too tight? I figure as long as it is working correctly, no need to adjust it.

 

[Papa_Lazarou]

I'd say leave your delrin well enough alone if you don't need to touch it. The "too tight" reference to this component of the reo is usually with respect to the mounting screw. It's a tiny thread and mounting into aluminum - very easy to overtighten it and strip the threading.

The delrin does not adjust, per se - it doesn't raise or lower. I think cj's issue was just a loose mounting screw and the delrin was not held in its proper place.

I tightened it until it was right at the edge of almost tight, so the Delrin was sagging 1-2mm, if you see old pics in the repair thread you will see how low it was hanging before the reo got sent to rob. It was like Matthee's pic above, but all the way across. After that I was just tightening a bit too light. Pushed the Delrin up until it was flush and adjusted the screw a little tighter until the Delrin sat flush.

That fixed a lot of my problems that have been occurring in the last 3 weeks.

Hand check while I build out this server.

Nice looking Server there Junkie. I have the option of putting two Processors in my home Dell sever, but only have one right now. Will put a 2nd in it soon.

Looks like an RM3 on a TRA. Good color combo.

Yeah that's the $30 guy I got off the co-worker who bought it on 03/12. It has upgraded BeCo, but stock 510.

The server is an IBM/Lenovo rig with some dual E7's and 396gb of ECC DDR3. I really dislike the auto-sensing bs that's on it. Everytime you pull the power plug out of the PSU it has to re-calibrate itself which requires about 2-3 reboots, the first one being a partial reboot. With that much RAM, the server takes about 8-15 minutes to boot, so flipping annoying. Especially when it's a test environment for my Software Engineering. At my job the nice Engineers build their own test environments and don't leave it up to overworked IT guys having to deal with (L)users. Also QA doesn't really have time for that nonsense either.

Yea, any gap there cannot be good. Mine are all tight and flush at all times.

Lesson learned!

over tighten = no bueno
Under tighten = no bueno

Tighten just right = bueno
