Best of Dnmun. BMS info, battery fix, etc.

Post by dogman dan » Jan 17 2017 8:06am

This is a sticky thread for some of the best information posted by the member Dnmun.

He no longer posts on the forum, but over the years he provided a great deal of information, particularly bms hacking and repairing.

FAQ asked the most,, how to parallel two packs, so they charge as one, through one charger.

Agree with the above. He helped me tame the throttle on a GNC bottom bracket system and sold me a resistor that was needed.

I followed his threads, well not the ones that were electronically over my head, but I liked how he set up a recharging station at his house and invited any of us to come use it. Never made it there, but always kept it in mind.

I have skimmed through page 99 of 693 pages of Dnmuns posts. This covers the last two years, pulling out the best troubleshoot threads, where the poster did what he suggested, and sometimes a fix was made.

Anybody wants to continue this, start skimming on page 100 and put up links to good threads.

Does anyone still have his name and address? I lost it and have a shit memory. Personally I'd like to know if he is alive or is taking his dirt nap?
Anyone? Please confirm?
Thanks Justin_le we're here thanks to you. All the best to the mods for their tireless work keeping it on an even keel.

dnmun is a good guy I'm sure, but where is dogman? I trust he's fine, but that his contribution is much more missed. dnmun's absense is kinda explained in his posts.


And also there's the people that get deleted without a trace.

Are you asking for confirmations, or providing them? :?

I don't know about now, but when I was a mod it was only spammers that would get completely nuked.

Awww :( that's unfortunate that he doesn't post anymore. I learned so so so much through him!!

Thanks for putting this together DD...I just replaced 8 bookmarks with this one :P

Dnmun, if you're still out there in the ether somewhere, I'd like to express my overflowing gratitude and appreciation for all your advice over the years! Hope all is well!!

Some one should re title this thread to "Best of Dogman and Dnmun". Dnmun did sort of tell us that he was tired of us before he quit posting but Dogman just suddenly disappeared. I have a personal message to him that is still in my outbox for a month now.
Dogman if you are out there somewhere we miss you and wish you the best. If not tell Dnmun we miss him too.
