Battery help.

[Max]

Them Hawker Cyclon cells are just really expensive lead acid batteries? I guess the advantage is i can dot them wherever i have free space as opposed to having all of the battery in one lump?

I already have Lead Acids in my workshop. They're pretty much perfect for power delivery but i think the weight is the killer with those.

It's starting to look like i have to make a decision between power delivery and weight?

I doubt you would use the single cyclon cells but woudonuse buy a 12v hawker Oddysee battery pack then wire 2 or 3 in parralel to get desired voltage. Hawker Oddysee SLAs are expensive but will be able to deliver the amps needed. Those SLAs you have in your workshop would probably not be suitab as they cannot deliver anything like the same amps (they may manage 50A rather than 500A) so would nt be suitable for your robot, they were used on early low power robots but are useless and weigh a ton for no gain.
For those motors your choie is only between good quality lipos or hawker Oddysee SLAs, I imagine they cost about the same so I would definatly go for the light weight lipos.
