snaker wrote:My old powerchair's battery box (a Quickie v121) has a 30A circuit breaker between 2 lead acid batteries. I see 30A circuit is too small and it actually annoys me much. When I move on rough roads or drive a bit fast continuously, it frequently breaks.
I am looking for a 50A circuit breaker for replacing. Can I use any 50A circuit breaker? Or do I have to need a breaker specialized for powerchairs which is safer, solider ...? In case the breaker is not an auto-voltage 12-24V, which voltage (12V or 24V) the breaker must be for proper using in the battery box?
Could anyone suggest me links which are selling good 50A circuit breakers?

You need to understand this. http://www.robotshop.com/media/files/pd ... dc2450.pdf all but the scripting and brushless bits. Although you will be loading scripts written by lenny and adjusting parameters in the user section here:

Not trying to scare you but make you understand whats involved. If you can follow most of that then you should be ok. You will need to make own complex proffesional loom, use own mosfet and power breakers controlled by roboteq via SSDs as well as inverter and ssd for brakes etc. Gets very complex, make own joystick, calibrate and set everything up correctly and safely. Its not trivial. But its not that hard as long as you can think and read!

And seperate connections that you can see?
Best bet is to charge them with a 12V charger in series as its healthier for the batteries.
