RoboClaw 30A and battery connectors

[Basicmicro Support]

You can do that or you could get the matting Deans connector(eg female for male etc). Then connect the adapter cables raw ends to the screw terminals. That way you wont make your battery unusable in other applications.

There is no specific requirement and we dont recomend any particular brand. We do recommend Lipo type batteries but if you are concerend with using Lipos NiMH will work ok as well. On bigger machines lead acid batteries are also an option, but you will probably want to get deepcycle leadacid batteries. Car batteries are not designed to be discharged very far.

One thing about screwing the battery leads straight into the controller: This leaves you with no off switch!
This is bad both for safety (emergency runaway!) and for battery health (LiPos die if you discharge them much below 3.0 Volts per cell.)
Even if there is a low-voltage cut-off, there will be some amount of draw on the battery.
Also, if it's wired straight to the controller, how would you charge it?

I highly recommend getting a mating male Dean's connector, and solder that to some 16 gauge wire and use that to connect battery to RoboClaw. (or coarser gauge if you're doing the 30 Amps and up thing ...)
