attempting to design a new robot.....

(1/1)

wannaB:
Hey guys, i'm the new kid on the block and looking for insights/opinions from the experts on what rechargeable battery to use on my new robot.  Anyone out there?????

newInRobotics:
Well, for best power to weight ratio - Li-Po batteries are best, although they do require some expensive chargers, otherwise they won't last long.

Ni-Mh batteries are next choice, they are heavier than Li-Po or Li-Ion batteries, however, chargers are cheaper.

If Your robot is a heavy-tank-like, then SLA batteries are good choice, they are horribly heavy, however very cheap (compared to two above), can take a lot of abuse, plus chargers for them are very cheap as well.
