9v Battery options?

[optima21]

They last as long as duracell

Remember, this is made of metal, has rubber tracks and 2 9v motors, for a toy it is very power hungry

you need to be looking at the current draw and working backwards from that then, as that can also have a bearing on the type of battery used

How do 9v square rechargables fair in comparison to the aa

Not tried them but will see what I have in thr cupboard

If you have an 18v drill or whatever, you could get another battery, part up it up into two x 9v ones that you then recombine to plug into the original charger. Might have to get a bit creative with wiring, plugs and whatnot but think it could work.

Might as well just buy the 18650 cells and a caddy.

My son's raspberry pi vehicle of a similar design runs on two of them.

What is the minimum and maximum voltages it will work with? Id use RC lipo cells, either one with a boost converter or several in series.
