is there a recommended battery ?

No real battery requirement per se but you would be wise to provide separate power sources for the motors and the processor you are using (assuming you are making a robot with some kind of processor for a brain).

The minimum requirement is AA Batteries. Otherwise, your battery choice is limitless.

It was the right battery for mine, but I would advise against buying this one. It held less of a charge than the one I was replacing and would suddenly kill the power to the computer at about 14%, regardless of the calibration I did.

Whatever Amazon supplies - I guess. I haven't had any problem with this battery and am so glad I bought it through Amazon. Saved a chunk of change.

I go thru maybe 2 fresh batterys a year. I say fresh, I suggest always right off the rack. also useage is important but I have been very happy.

any double AA battery, I would recommend buying the ones that typically cost a little more because if you buy cheap ones they will die very fast

I use a marine battery from Wal-Mart. It works great and the cost is reasonable. I use it in a 15-foot jon boat and it lasts all day.

Wow, that is a good question. I have not used any other battery besides the lithium rechargeable battery it comes with and I am not sufficiently "geeky" to feel confident advising you about this.

Yes. It's a great replacement battery. Just got it about a month ago and have had no problems with it.

I went to a local BatteriesPlus store. They were incredibly helpful, and I know customer service and future attention to my needs will be better than if I bought the batteries online. Remember, batteries have a limited life-span and will need to be replaced. Buy them somewhere you can trust for reliable and consistent attention in the future.

There is a battery recommended in the manual. The best place I found to buy it was Amazon, but Interstate has them also.

Not to be a "brand-hog" but I would recommend simply purchasing a Tenergy or Tenergy-recommended charger in order to get the most out of these batteries. Mine are over three (3) years old and still like new!

I found the battery life to be great -- I used it a lot and it never ran out -- but I had a backup battery and would always have one. An external charger is a good idea too.

I used Energizer A23 Battery (12 Volt), as recommended, one battery will lase longer to six months.

I would recommend ordering an XL battery as. A backup when you extended time of operation

Anything 4000 mAh or higher should work fine. 11.1V is the critical part, 8 cell will give you more battery time than 6 cell

Tom, I got my battery from the manufacture but I think you could check places like Battery Plus. They may have the battery or a similar set up. Good luck!

It's good enough unless you're constantly using data. Google battery university and look at their guide to Li-On batteries. You'll learn how to get the most out of the battery.
