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.
