Wiring for regen

On my application I have a removable battery. For charging and its out of the bot when its stored. So even with a diode pathway to dump the regen current without the battery it has nowhere to go. So what is going to happen if I have the battery out and the bot happens to roll some? Also the way I have it wired up is with a relay. Using the normally closed side for the pathway for the regen current with a diode. Do you see any problems doing it this way. The controllers with the can bus will be here in a few days so I want to have all this finished up. Thanks for getting that taken care of for me.

The simplest and safest thing to do is to ground the power control line when the battery is out. This will shut off the controller totally and if voltage is generated from your motor because you are pushing it, nothing will happen.

What if I need regen up to a certain amount? My controller can handle 60V max. I need to allow regen for up to the max. Will the controller's overvoltage protection do the trick and shut off the controller when regen exceeds 60V or do I need to take additional precautions?

I am talking about the configuration where the main battery is disconnected during regeneration. How about then?
