The child level betamon is capable of generating 1,000,000 Volts of energy, This comes straight out of digimon adventure 02 and from the digimon reference book, To give you a comparison, Pikachu's thunderbolt is equivalent to 100,000V meaning Betamon is capable of generating 10x the electricity of Pikachu and he's only a child level digimon. Another digimon that works with electricity Thunderballmon who's a mere adult level produce 10,000,000 volts of electricity equal to pikachu's Z-move. In other words one of the strongest pokemon moves in the anime is comparable to a low tier adult at best.
