Yeah, we don't have rechargeable "AA"s here in Canada... we still use oil lamps to light our igloos...

I have a drawer full of AA rechargeables.... really should throw them out... they are crap, but good for those solar powered deck lights...... Hmmm, actually my inMoov eats them like skittles...;) Or maybe you suggest I should replace his 6V 12ah sla battery with a bunch of "aa's?

The ops batteries actually could barely drive one servo... He'll probably buy some Lipos and will be much happier for it...

Let it lie Steve... You really going to "call me out" for dogging on "AA" rechargeable batteries? You use your "AA"s and I'll use my Lipos and SLAs.... everyone is happy...

Richard, Watch again the vids powered by AA. You are so entertaining, creative, and assertive. I was not putting you down. I am glad we have you on our forum. You have created some great EZ Robots!

Figured i'd jump in on the conversation, I'll be pulling info from a number of the posts in this thread and will add in my own experiences as well.

The OP is definitely experiencing a brownout (voltage sag) resulting in the ez-b resetting.

So, Yes, you can run 2 continuous ezrobot servos with either 6 x NiMH or NiCd 'AA' rechargeable batteries but here are a few things to note:

• Using NiCd batteries with a lower capacity rating is ok because NiCd's can deliver very fast inrush current. Keep in mind though, a lower capacity means that the servos won't run for too long before the batteries need to be recharged again

• When using NiMH batteries they will have to be a little higher in capacity to make up for their slower reaction to inrush current. I use 2300-2500mAhr.

• Mixing capacities (mAhr rating) of any battery type is not advisable as the lowest capacity will be your limiting factor. If your lowest battery is 1300mAhr, it will be the first to run low and it will drop your overall voltage very quickly

• Due to the chemical change inside batteries (i.e. sulphation, crystallization, whiskers, memory effect, etc) over time any battery type will degrade and loose capacity. I have many rechargeable 'AA' batteries that will charge to their full voltage but when used they will go flat very quickly due to being old and having a much lower capacity now.

In this case, I would do just as @Mohamed.r is already doing, I would purchase some new 'AA' rechargeable batteries.

Alternatively, I would also recommend looking at moving up to LiPo batteries, as they are very powerful for their light weight but I'd say definitely work with what you are comfortable with until you are ready to make the leap

I have 1300 mah recharge energizer batteries I have 4 of them and I'm mixing them with the 2500 mah nimh recharge batteries if I buy another 2 1300 mah energizer batteries will it be able to power the robot similar to box bot as buying a lipo with the connecter will cost a lot because of shipping and the 1300 mah batteries are new batteries that I just purchased And i would hate for them to go to waste and if getting all my batteries 1300 mah will power my robot that would be excellent

hi guys im sorry to bring an old thread back but i have 1 nd a half months holiday and i would like to buld my robot during the holiday the lipo battries from ez robot is to expensive so i wanted to know if i purchase 6 new aa battries 1300 mah energizer recharge battries will i be able to power by entire boxbot the batteries are nimh 1.2 v

the batteries

@Mohamed.r

Those will work for a very simple boxbot. I run one that just has 2 continuous rotation servos and hte camera, and I use 6 Enloop NiMH batteries. But more than a couple of servos and you will get brownouts, and the bot won't run long on those batteries. Maybe 10 minutes of movement.

If there are any hobby shops in your area that deals with R/C planes or cars you may be able to get a LiPo without the shipping costs from EZ-Robot. Any 2S Lipo will work.

Ok thanks
