Dustbuster voltage change
Hi,
It is exam season, so to avoid work, I am experimenting with a dustbuster. I want to change a 7.2v to a 9.6v (the 7.2 batteries dont work) - I have been using a model car NiCad pack and the suction is fantastic and the motor still remains cool. The only problem is the battery pack get very hot! How can I prevent this? Ideas I had: 1) a resistor to limit current flow - loath to do this as it will reduce motor speed 2) 2 9.6 packs in parellel to share the load between them and so keep them cooler. 3) A different type of battery - NiMH/Lead acid I know that buying anew one is easier, but it is the experimenting that I want to do! :) Thanks squelch41 |
Well I have a Makita vac that's 7.2V and have been running it on 9.6V
going on 7 years now. It rocks. The end of the pack is identical and the salesman that sold it to me showed me the battery switch. The only thing that has happened is that the impeller needed replacement last year. That cost about $7. The Makita batteries have built in thermal protection. Richard |
