Is there a reason why..

Is there a reason why a battery company hasn't come out with a higher amp battery?? Is it because of lack of technology, safety, lack of demand or its not neccesary?? Is there an answer?

For the most part the major battery manufacters (there's only a handful really) weren't very happy that we are using their flashlight batteries for vaping. Especially when sub-ohmers do stupid shit like not paying attention and blowing them up. They don't cater to our market at all, were kinda like a bad mark on their list.

The main market for most of the batteries used by vapers are OEM makers of battery packs for laptops and cordless power tools etc.. These are then sourced on the wholesale market by those who then market them for other uses. Technology for these batteries has been fairly stable for the past several years with some tweaking of chemistry for the hybrids. What it boils down to is a trade off between amps and mAh. More of one results in less of the other. The hybrids are a method of getting higher mAh without giving away quite as much in the amperage department. Thus 20 amp 2500 mAh or so ( VCT-5 - LGHE2 and 4 - Samsung25R etc. ) or 30 amp 2100 mAh hybrids ( VCT4 etc. ) or straight IMR 30 amp 1600 mAh or so ( VCT3 etc. ). Higher amperage may come but it would likely be driven by those OEM's needs not ours.

also technology of batteries has a very real max. thats why a car battery still is as big as it was 20 years ago. its old tech

The form factor of the battery makes it popular for a lot of laptops, power tools, etc .
That has changed. Look at the the thintops out there. Look at cellphones too.
The tech moves forward when market forces drive it.
Here's just a few examples.

This - it seems the former big-time users of 18650 batteries are switching to li-po packs, leaving the 18650 out as kind of old tech...

You got it. Early on there were laptop and cellphone fires. Industry learned. If you take apart a current laptop pack. you will see they charge and monitor every cell independently to avoid this while using unprotected cells. It is externally protected. This fits in with using lipo pack safely in new devices. Just change up cell form factor - then continue to use same circuit to monitor just a few cells.
Laptops use several batteries in series, some do parallel/series. Tell tale is voltage and aH rating of pack. But there aren't that many cells involved. The Tesla car uses a wall of batteries in series and parallel. Boeing, too. Complicates individual cell monitoring using laptop model. They went to using the protected pannies in big packs. Avoids having a shit-ton of wires to monitor each cell in a pack, making it all self contained - the circuit in a protected cell constrains output current (short ptotection) and overvoltage (charge protection). A single fucked up battery in a series/parallel pack could go unnoticed by a simple external charging circuit and cause the other cells to catch fire from overcharging. A series/parallel arrangement is used to up the voltage and current capacity.

Within the next couple years, mod makers will have to transition over to LiPO packs. The biggest market for traditional lithium cells is flashlights and vapers. Even power tool power packs are now starting to use LiPO batteries. It's just a matter of time.

this flashlight would benefit from a lipo pack. Round flashlights are handy when needing a club.

The reason is humanity is simply at the limits of understanding in battery science.

Lithium-ion is very promising, but at this point we are making hundreds of small tweaks, over and over which steadily improve performance. Drive is for higher capacity rather than higher amp drain as electric cars need a certain range to gain mass market appeal - and they use more batteries than any other devices.

All the research is on the nano-meter scale. Playing with the surface structure to enable a more efficient flow of lithium ions that is.

It will most likely continue to be improved at a slow and steady rate until a major break-through is found in lithium-ion, or in another battery chemistry altogether.
