Hi I was wondering what is the best digital voltmeter displayed adjustable step down voltage regulator to use with the ezb v4 when powered by the ez robot 7.4 vdc lipo battery or battery's of a higher voltage. I am planning on buying the ez robot lipo battery but I plan on using higher voltage batteries later on for more power and longer life but I need the right regulator so I don't kill the ezb v4, sensors an servos. Any one know what I should buy? Sorry if I ask a lot of questions I just hate to blow up my equipment before I can us it. Im new to the robotics thing
the one sold in the store should do best https://synthiam.com/Shop/AccessoriesDetails.aspx?prevCat=9&productNumber=98
You can power the ezb up to 17v or so.... However, servos won't work at those voltages... It's best to use 7.4 lipos for any project with servos... If you absolutely need to use a higher voltage battery you will need to either power the servos separately with a 7.4v lipo or search eBay for a step down voltage regulator that can supply lots of amps... I suggest a minimum of 20amp adjustable bench regulator... Servos need power that's why it is just so much easier to stick with lower voltage LIpos or niMh when using servos in your projects...
You will always need a 5V regulator for sensors like pings no matter what size battery you are using....
@bborastero That regulator is only good for sensors like pings as it only outputs 1amp... Probably wouldn't even drive 1 servo....
I use an lm7805 to cut volts to one of these servos because 7.4 freaked them out https://content.solarbotics.com/products/photos/7f654958712313246f3e29a35278d71c/med/25500-dscn3970.JPG https://solarbotics.com/product/25500/
bookmark this page as reference, it explain powers requirements for the v4. I believe the V4 can go up to 16v. The problem is the power going into the v4 will also get distributed to any device plug into it. The safe Voltage for the V4 with components will be a 7.4v. If you are working on a larger project that require more voltage etc. You will need a voltage regulator for the components (sensors, servos, LED's etc). I personally use this
Voltage regulator. It work well for me.
1amp would be ok for micro servos, but I doubt 1amp would be enough for even 1 heavy duty ez robot servo...
@PJ_Dtechy nice i like it and will be ordering a few thanks
@PJ_Dtechy That voltage regulator is only rated at 2amps... Again, the problem is it can't supply enough power for a robot that has many servos... For example, when you first boot Six the inrush of current of 12 servos will exceed 10 amps... It would probably blow that regulator....
