Connecting question

[Dragline]

I remove both AGM batteries in the fall keep at the house so I can trickle charge them a couple times over winter, when disconnecting I remove both negatives first then positive and when reconnecting I reverse what has bothered me from the first time to present is the large arching when connecting the negative side...Normal ? I would think not but I’m no electrical engineer to the point of understanding all the intricacies involved.
Thanks

The arcing you see is why you need to disconnect the batteries in the first lace. That is from all the parasitic loads re-initializing.

To Terry's point, it's a good idea to make sure everything in the trailer is turned off, and shore power unplugged to avoid the charger/converter coming on. This will help minimize the arc.

Makes sense, to your point, it’s aMaking the draw on the batteries that a person doesn’t realize or thinks is minimal due to “everything being turned off” would it help if a person initiated the storage mode for the batteries prior to disconnecting?

I leave the batts in the AS, disconnect switch engaged.
I use a switch on the LP detector, the AS use/store and a aftermarket battery switch, remove the stereo faceplate and make sure the antenna boost is off.
