How many batteries do I need for the MAH3-R hexapod?

The question is the same as the subject, where can I buy it?

In addition, why the BH3-R is more expensive than the BH3 hexapod?
How to choose between the BH3-R, BH3 and the MAH3-R hexapod?

BH3-R: lynxmotion.com/p-863-bh3-r-c … sc-32.aspx
BH3: lynxmotion.com/p-963-bh3-com … duino.aspx
MAH3: lynxmotion.com/c-157-mah3-r.aspx

The MAH3 is physically larger, but since the servos are also larger, the carrying capacity is not significantly increased.
The choice between the three is actually mostly based on your tastes.

We’re looking into the price discrepancy between the BH3-R and BH3 and thank you for bringing this to our attention.
