  • Powertool batteries: I can get 2x2AH or one 4AH battery.

    Setting aside the convenience of two batteries, will I get roughly the same out of both. I'm sure I've seen comments online that as smaller batteries drain they provide less power so something high drain like an angle grinder would be quickly into that reduced power state. Or is that bollocks?

  • You also get more power from a bigger battery. I don't know why because I don't understand electricity, magic perhaps.

  • My (amateur) understanding:
    better connections between individual cells,
    thicker wires to deliver power to the electric motor.
