So if that is the case...... What exactly is that battery eliminator for?

It can be used in place of a battery on some motorcycles that have permanent magnet alternators and a kick start. It's basically a large capacitor that helps smooth out the voltage.

When your bike is running, the generation of electricity is not constant. It actually fluctuates as the engine rotates and sometimes it's a bit too much power than needed and sometimes it's a bit too little. The voltage regulator tries to keep things in check as best it can, but a battery (or battery eliminator) is also a piece of the puzzle.

Yeah, the generator/field coil descriptor is key. Our 750s have field coils.  Unfortunately, those field coils are one of the achilles heels in the 750s charging system.  They are known to go bad as the epoxy breaks down around the windings and they start burning up to gain resistance.  I think having them exposed to hot oil is the source of their demise over time.

Ok so I do have to run a battery..... Got it.

I can still ditch starter and it's components.

Now looking for suggestions for a safe lo-pro battery that won't eff my bike up.

That battery mentioned earlier (lifePO4) sounded like there were strings attached lol.


I just wanna keep it small.


Thanks.

Gotta say... I'm not a fan of how that battery eliminator is being advertised. Some of those claims are dubious...

Sonrier can let you in on the specifics to the Earth X batteries he sells.  I have killed two Shorai LiFePO4 batteries from accidentally leaving a switch on and draining them.  My fault, but I want things dummy proof (me being the dummy).  I have two Battery Tender LiFePO4 batteries, which is what I have on a CB550 i just built.  They have special protection circuitry, so when you let them discharge accidentally, the circuit actually shuts the battery off and you have to hit a reset button to run again.  Once reset, you can go back into charge mode and bring it back up again.  I tried to do the first start/tune on that bike with the Battery Tender battery (like I said, me the dummy), and all the starting discharged quite a bit of battery, so I learned all about it's protection circuitry right away.
