sealed lead acid Battery Spark?
I plugged in my 12v 24AH batteries into my wheelchair motors, not realizing the brakes had to be disengaged, I saw a huge spark as I disconnected, and some got on the floor. The motors ran fine after wards. My question is, is this normal for such a high current drawing device to draw a spark when disconnecting?
Yes. It's normal to get a spark when disconnecting a battery from a load.
(A little technical bit) The size of the spark is directly related to the size and type of the load. If the load was brakes they might well be electromagnetic in which case the spark is likely to be greater due to the back emf generated as you disconnected.
