A better way starter solenoid

Is there a better way with the newer batteries than using these clunky old solenoids to get power to the starter.

The solenoid's main job is throwing out the gear to engage the flywheel, making the contacts comes along for the ride. That is why the solenoid is so big.

Depends. Some solenoids actuate the bendix, and some do not. Those that do not and use the starter bendix's inertia to engage it, you could change it as long as it was rated at the same or more amperage.

But the "inertia" comes from the starter as it winds up, so the inertia adds to the electrical load through the starter contacts. Same-same.

No, it is not. Some of the solenoids mounted on the starter also use the electromagnet built into the solenoid to engage the bendix. You could not just take it off and use a starter relay type solenoid. Sure the starter will spin, but the bendix won't engage.

The older GM starters are like this as many others are. Now the older Fords had the solenoid on the fender. And I correct myself as the older fords used the outer windings of the starter for the electromagnet to pull down a steel lever that engages the bendix.

The type that uses inertia has very course threads (if you will) on the shaft to engage the bendix. The shaft of the starter spins faster at first forcing the bendix up the "threads" to engagement.

you are sending a lot of amperage through that solenoid.  Not sure what new battery technology has to do with a way to send the juice to the starter without using a massive switch to run that much current through.
