why engines with alternater has really tiny battery in it?

[omelaw]

it won't matter at any practical standards, so I guess it's techincal issue. but solar panels doesn't have battery, so, I'm run out of idea.

I guess its because of some problem that needs engines to directly feed into their own power bank… But the EC capacity is like, 0.1 units, so it isn't much of a unbalance. But I did have some cases where I had a lot of engines on my rocket and I got +1 unit of power from the engines "batteries". Maybe someone who knows how these things function can tell us more about it, I only got my feet wet in this system.

Funny you're saying that now, the 1.2 beta doesn't have that batterie anymore.

At least practically, the info screen shows 'electric charge = 0.0'.

I assume it is meant as a buffer, or that alternators have some weird quirks.
