Electric vehicles have a future in armies, especially when it comes to light vehicles. EVs have a lower heat signature. The Russian military is experimenting with using electric motorcycles that they are using in their storm trooper units. I am not very knowledgeable in this area but I have heard of weapons that take out electric devices.
Electric tanks would be less noisy and there would be less of a risk of a fire. I wonder how they manage this technologically. Have you seen a Tesla Truck trying to climb a hill? Have you seen Tesla on fire from a damaged battery? Mind you, these tanks will be hit with rockets and suicide drones flying at high velocity, and one would need to pack a shit loads of power to make this thing run.
At the end of the day, there are weapons coming out of research and development being introduced into production only to shine at one battlefield and totally suck at another. Also, war makes weapons quickly obsolete. Think Bayraktar, Javelin, or even HIMARS. Think of the horse in WWI…
PS: This allegedly is an electric off road bike from Kalashnikov…

There’s American company Howe&Howe which made electric remote controlled tank, you can check the video easy to find on you tube.
So advantage is obvious if you want remote controlled tank, and well since it’s without crew, it’s quite good for contested risky areas, primarily urban. The main flaw is obviously that you need to haul it to the battlefield.
Platform could be used to create remote controlled minesweepers. But batteries would need to be bigger.
Also small drone tanks with fuel are far better than electric ones so far, just judging from their you tube channel, their electric mini tank gets stuck in mud easily. They solved power issues by putting smaller tracks, but this make their tanks, bigger and smaller ones prone to stuck in muddy area.
So yeah Bakhmut type of battles maybe, but in muddy steppe no way.
PS Elon made some maid robots, but they’re looking sloppy so far.

Basically, if it is crew-less, you don’t need the cabin, and its space could be filled with a battery. But little damage to the battery will cause a fire. And what you need first and foremost is to deliver the firepower to the spot to take out the sniper or some other fortified firing position. Fire can cause secondary detonations. It would need a lot of innovations to be successfully exploited.

A lot of it are about money. EV makers are trying to make money. However, if money is the priority, then product’s quality and even usability may be forfeited or even sacrificed as the result. But nothing will stop buyers from buying junks after some convincing, and it gets analysts all worked up too.

Yeah those electric bikes are silent, that’s why they’re useful, plus it’s not that hard logistically to get them to front.
