All tutorials show a 7.5 v battery pack hooked up to the EZ B. The kit comes with a 9 v battery holder (6 x 1.5). Am I missing something?
Personally I use a 7.4v LiPo battery pack, these are very light and come in a range of sizes.
The higher the voltage the hotter the regulators get but it's easily cooled down with a mini pc fan if the heat is too much.
Using a 5v supply will probably cause more brownouts than using a 6v, 7v, 9v or 12v supply.
Now factor in if you are going to runa hbridge which needs it's own dedicated supply to feed the motors, if you are, what voltage motors are you using? You can take the supply from the same battery just not from the EZB.
Also, if you plan to run 6v to the servos power to increase torque and reduce current running through the EZB you also need to think about the supply.
In short, you haven't missed anything but the EZB can use a supply of 5v to 17v. Don't be put off using a higher voltage supply because of the regulators, that's why they are there
this is what i have done, the battery packs will power the Thumper motors with 3 H-Bridges and the EZ-B, you can see the pigtail. One side to charge and the other side to power the EZ-B.
I can charge the batteries and not have to worry about taking them out.
Do you charge with it connected to the EZB?
But from ready other posts it will work without any problems.
