Roli Robot Questions

Question

With the roli robot would I be able to use higher mAH like traxxas or these duratrax 7.4v 4,000 mAH batteries https://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXBPGW&P=0 and still be ok? Also is there a way I can use one 14.8v battery instead of two 7.4v batteries?

Rich · Accepted Answer

From what I've read the EZ-B V4 passes the voltage through to the digital ports, i.e. if you feed in 14.8v you get 14.8v on the VCC of each digital port. So some kind of regulator would be required. That said, space is the only thing that restricts what you can use, a 4000mAh 2S LiPo (7.4v) should be fine provided it fits in there, or on there. You may need to make some adjustments (unknown until we see detailed pictures of Roli).

Higher mAh just means more gas (or capacity)... Voltage is another story... So as Rich says... as long as you can fit the 7.4V 4000mAh battery in Roli, you'll be fine... If you want to use 14.8, you should find a way to get it down to 7.4v or so for Roli's motors...

I know the mAh increases capacity which is what I'm after. Do you think one 7.4v battery can adequately power both motors?

Robot Doc · Answer

If you can determine what the current consumption of the motors is then you can determine how long they will be able to run using a 4AH 7.4 battery pack.

Roli Rover uses 2 x LiPo Robot Battery 7.4v 1300mAh You can fit larger mha batteries within the shell - but I would definitely not run 14 volts!

DJ: "Revolution Roli uses 2 x LiPo Battery 7.4VDC 1300mAh" Contentlist of Revolution Roli at the time of my purchase: 2 x LiPo Battery 7.4VDC 1300mAh 2 x LiPo Balance Battery Charger Now its: 1 x LiPo Battery 7.4VDC 1300mAh 1 x LiPo Balance Battery Charger Which one is right? If Revolution Roli uses 2 x LiPo Battery I would guess the first one, that also includes a 2nd charger.

I've order a Roli and extras in February and would like clarification on amount of batteries with my order. thanks

stibaer · Answer

I am also fine with only one charger and some arms instead;)

Zap Brannigan · Answer

I'm a little curious about this one too. So Roli requires two batteries but is only going to ship with one? When I order do I need to add another one to my order?

coryBlair · Answer

This thread is out of date. Roli will come with 1 LiPo battery. There will be room for two battery's if you wish to add a second.

bborastero · Answer

I'ed forego battery for arms anytime but the order at the time did state 2 batteries and two chargers

stibaer · Answer

Same for me. It even was the reason to buy the Roli.
