I do it that way when I need to.

Two points:

1. In the original design there is a fuse in that circuit, so one has to be sure the charging current will be limited, either by using a small trickle charger, or making sure the batttery is not discharged to any great extent when you plug it in.

2. If I recall correctly somewhere along the line the design of the power plug circuit was changed so the connection to the battery is not direct, but through the solenoid so it is not always hot.
