Just waiting on the weather to break so I can finish mine. I'm rewiring all my light mods and train horns to two junction blocks off of the second battery. I figure it'll be a two day event so I'll need it to be nice out so I can ride the bike if I have to go somewhere.

...and added my surplus Battery Brain as the method of combining them.
Took a step backward today. The battery combiner situation had been bugging me. The Battery Brain had no way to tell me when the batteries were indeed combined. Remotes are cool and all...but did I really need more of them? The one time I did need it I went under the hood and switched it manually. I had neglected to add a wire that allowed that to work when it sensed low voltage, so I ended up using jumper cables. I did fix that problem, but neglected to turn the manual override off 

KISS.

I replaced the Battery Brain with a $14.99 Dorman battery disconnect switch from Oreiley's Auto parts.



Pull the key and put it in a hole behind the battery. When I need them combined, put it in and turn the key. I know they are combined. No remotes. simple.

Yeah... I've only gotten around to putting the tray in. The isloater and cables are enjoying the warmth of the house right now.

I'm collecting parts to do this too.  Got the tray, hold-down and bolt, sitting in the garage.  I've also got a Stinger 200A battery isolator sitting in the garage.  Since I plan on running an Optima (which is for now operating as the only battery in the red AV) as a second battery, I didn't want the batteries connected when the ignition was off.  With the Stinger, the batteries should be in parallel when the ignition is on, and separated when the ignition is off.

Alrightttt Main One!  I purchased a 80A battery isolater from stinger as well and was curious as to whether that'll be strong enough?  How do you decide upon the correct Amperage Isolater you need?  Do you need anything other than an Isolater?  I hear talk of a "Combiner"?  I'd like to just wire everything up so that the main battery is untouched when running accessories and then after start up they both charge. 

I'm buying another ACDelco so they're the same battery.
