I have the SW electric focuser, which as Adrian says, drains the battery
even when not in use. I fixed that easily by putting a little on/off switch to the left of the speed adjusting knob; half hour's work, and $5 for the switch; now works as good as gold. The electric focuser would struggle with lifting that amount of weight however.
To be fair, I doubt any other budget level focuser would handle 4.5 kg very well either. Mine handles around 3 easily enough.
