Location: Cedarburg, Wisconsin | Not really. You can run 2 in parallel with one in series for 24V, but other than getting a little more power when you first start out, you would be disappointed with the results I'm afraid. You need 24V to get max speed out of your motor and as the single battery wears out so does your 24V even though the other two in parallel would have gobs of reserve. You would be able to run longer in theory, but you would probably only get slow speeds as the max voltage you had available diminished.
So would it be worth the effort and expense to rig a system this way? For the little gain you'd get, I doubt it.
There is another way to do it, by creating a voltage doubler circuit on one battery to put in parallel with the other two in series, but by the time you got done constructing the circuit you'd be better off just getting a 36V motor. The more complicated you make things, the more likely they are to break and be unrepairable while on a trip.
If you really need the extended run time on a 24V system you need 4 batteries. |
