their voltage is combined
Think of it as several packets of energy…
A single LV battery box with two batteries in it can output 2 packets (amps) * 32EU, which effectively becomes 64EU/t. So if you put a batbox right up against the electrolyser with no cable/wire inbetween (so there’s no cable loss) and use two batteries in it, it can easily power the 64EU recipes.
