Holy shit! That Lincoln setup is all you will ever need. Congrats again on that, man!

Keep up the good work, the scoot is looking fantastic.

That's badass. I haven't been to Handbuilt in a couple years. Are you out of Texas? I'm in Houston.

Not in Texas - but only about a 10 hour drive from Austin, been out there a couple of times for SXSW (for work), but never by their shop.

Got a new battery from Sparck Moto - the thought was to get one small enough to mount just about anywhere in any orientation. I still wasn't 100% sure on the direction I wanted to head with the bike (still not).

I've only scanned over all the posts here so maybe I missed it, but have you upgraded the voltage regulator? Modern batteries need modern (MOSFET) voltage regulators.

I know EarthX uses some sort of battery protection circuit to protect from over charging, but I also know what an EarthX smells like when it self destructs due to over voltage being fed into it. Once the battery begins to fail, there is nothing you can do to stop it, you just have to stand there, watch the light show, and hope nothing actually starts burning. Stand upwind.

To be fair I have been told (by EarthX) that they have upgraded the over voltage protection since I had my little issue, so I kinda doubt your bike puts out enough voltage to hurt it even unregulated, but better safe than sorry. You do NOT want that thing losing all it's smoke, and trust me, they hold a LOT of smoke. And it smells horrible. The "holy shit I'm pretty sure I shouldn't be inhaling this" sort of horrible smell. Im also guessing the LEDs would appreciate a more modern approach to voltage regulation but I'm no LED expert.

My '91 Ducati 851 now runs a modern voltage regulator and a voltage meter along with it's (replacement) EarthX battery.

So to recap:

If you want to run a modern lithium battery, you should also run a modern regulator. And a voltage meter.

Also just to be clear, I don't blame EarthX for this, Post-meltdown testing showed the voltage regulator was shot. I also lost a circuit in the ECU, plus the headlight and a fuel pump relay failed soon after. Maybe a coincidence, maybe not.

Suzuki R/R are always a suspect component. Even the 2008~2010 are crap and can cause fires with 100% stock set up. (I was teaching 'FAST' at MMI from 2006) plus I worked in Suzuki dealers in 1980's. Some are OK  ('Intruder' where they had to be mounted close to left silencer) but they have always used the cheapest components available. It's kinda like the LUCAS of the Japanese bike industry. Lucas could actually make really good parts, just not at the prices demanded by manufacturers.

I upgraded the reg/rec (got one from Sparck) pretty soon after I started working on it. I also added one of Rick's Electrics stators about a year ago. I ended using their reg/rec combo once I made the swap since it came with the stator.

But as of tonight - my EarthX is dead. After talking with EarthX it sounds like it has a dead cell (won't charge above 11.5ish). Not sure what happened to it - EarthX said that the battery was compatible with Rick's charging system.

Now I am trying to figure out what to do for a new battery without shelling out a lot of cash, since I have get my truck re-painted pretty soon.

They're very cheap, but, powersonic actually has decent batteries. The company I work for purchase from them for something like $3 per battery lol. I have seen some on amazon for $39 or something that would support our bikes. Weird that your EarthX isn't holding up though.
