Ended up ordering and receiving the wrong model battery for my RadRover.  The connectors look the same, both are 48V and polarity.  The little plastic tabs that interface with the connector plate are a little smaller/less heavy duty, but look like they're in the same place and it does snap in place securely.  The smaller RadMission battery is 10.5AH and seems to attach solidly to the bike -- but I chickened out on turning the key and powering on the bike for an actual test.  The official position of Rad is that this battery is not compatible with my RadRover and cautioned me against trying it.  Then they tried to sell me the 15AH version.

Anyone know if this battery would be compatible with my bike?

Thanks!
