I am new to the the hexapod game and am starting with mostly lynxmotion components but my
own controller. Does anyone have an estimate of the max amount of current consumed by the
servos? I was planning on provisioning a 3 amp switching regulator per 3 motor leg.
George
That should be more than sufficient. Good luck!
Agreed, that’s a total of 18 amps so you should be in a good place. 
I also need to provision for 8 tail & 4 head servos. The power supplies will occupy the
entire PCB!
How much battery weight/capacity do most lynxmotion style hexapods carry?
George
We recommend a 2800mAh NiMH battery for the stock 18 servo hexapods. This is a conservative solution at a reasonable price. The technology is considered safe. Many people use LiPo batteries which usually means a regulator is needed. I have seen LiPo batteries up to 8000mAh used in them. The 2800mAh battery is 9.52 oz. and the 8000mAh one is 15.04 oz.
Of course this all depends on the run time you require. If you don’t need a long run time, then you want to keep the battery on the smaller side. Battery capacity must be increased if the run time is too low or more payload is required.
Are you running the servos straight off 7.2V batteries?
George
Oops! No we are using the 6vdc NiMH pack.
