Fixing battery issues in a Lavabox DNA200

[Drumtrip]

So I have already had this Lavabox repaired by Evolv once, and now it just came out of warranty so I can't get it repaired again. I am wondering if I can slavage it myself.  The Lavabox itself is a poor design, at least mine is, the slightest leak from a tank seeps in to the 510 connector and runs down the chip. I generally run a Griffin on it which I keep pretty sealed but some leaks are inevitable, and I clean them as soon as possible.

I now have the same issue I had when I sent in the chip for repair the first time.  Cell 3 reads 0.00V and therefore the whole pack reads 0.000Wh and won't fire.  I opened it up, there was a little bit of juice in it, which I cleaned, where I think the issue lies is that juice gets in the channels under the white battery connector. 

Anyone else ever run in to this issue? Is it salvageable without replacing the chip?  I am thinking if I desolder the battery connector and clean it all out under there, maybe I can clean a possible short if the chip isn't blown. Overall I am pretty much done with this mod so this would just be a weekend project to see what I could do. I wouldn't make this my primary mod again, the design is just horrible compared to my Therion and Reuleaux.  Just seeking advice to see if this is a fruitless effort.

First thing to do is open a help ticket with Evolv from their website, regardless is you're past the 1 year warranty of their board. They might still help you out. My understanding is if a new board is installed, the 1 year warranty, for that new board, starts over. (help desk link is in my signature at bottom of page).

If for some reason they can not help, you would need some knowledge of electronics to diagnose and repair a mod. You may also need some soldering skills, depending on the situation. Usually if any cell is not registering on Device Monitor, it's due to either a broken balance tap wire from board to battery tray or the BMIC (Battery Management IC) has has failed.  The latter is the most difficult and requires the use of a  hot air soldering station.
