P700m4 Battery

[Harman24630]

I've read some post about adding dual batteries and recently seen where someone (can't find it again) planed on just having a larger automotive battery in a different location. My question is what about a deep cycle marine battery as a replacement or secondary?

Anything would beat stock. Most guys that switch to automotive style use an Optima yellow top which as I understand is as good or better than duals. This is on my to do list as well!

i know I would b sacrificing cold cranking amps but how important are they to a 675cc single cyl engine or a 4500 lb winch. I guess my questions would be... How much at the very least would crank the engine and how dead is dead for a marine battery

I have a group 31 die hard platinum in the pick up which is a marine battery and its up to 1350 CCA maybe more cant remember. Any car batt will most likely have quite a bit more CCA then the stock baby battery.

I'll be subbed to this thread as I'm interested in fitting a batt in the front storage compartment.

I'm thinking about fabing up something under drivers seat for battery and using the stock battery box to install an accessory fuse box.

I ran an extra battery under the hood because I had a speaker box under the seat so I had to make a complicated battery box and run cables. @Tflynn is right it seems that under the seat is the best spot it's where most mount it plus your main is there as well so less cables

I used the empty space under the drivers seat. Just make sure that you use a fuse or a circuit breaker on the battery to prevent any electrical melt downs of the vehicle!

Are u still running the stock battery with that one or just the optima?

 

[joeymt33]

Using the optima only. I used the stock battery location for bungee cords and stuff.

If I could suggest something. Use one of these off of the second battery before you connect to fuses or any accessories. It will give you back up protection even beyond a fuse box and will allow you to connect or disconnect everything all at once. If you have a problem or want to add something. Even storage just push the button and everything that's not Honda is totally off. Cheap insurance.

The bigger single is nice, however I prefer dual batteries. I can jump myself.

Don't need to with an isolator. If you're going to run anything while it's not running two is the way to go

Rarely ever be doing anything without it running unless it's the radio on a beer break. My larger concern is with running a winch. I have a winch on my rancher I use to lift and lower my snow plow and if I use it a lot i have to ride it around abit to charge the batt back up. And I am certain the cute little stocker won't stand much of a winch... Or a long beer break.

I really would suggest a two battery setup. Put an isolator in between (preferably diode type as they never connect the two batteries, charge the stock as priority,easier hook up,don't take any juice while on and don't need to be run to ignition) and run everything you hook up to the new battery. No chance of having a problem and hurting the factory setup it's easy to turn off and store but best of all never a dead battery even sitting there drinking a beer with the radio on.

This is what I built, however I build my trucks the same way. Never be the guy with the best stereo, lesson hard learned.

Usually on the bullet bike. Seems like the Harleys get more attention now days.

I put a Duracell deep cycle 120AH under the hood of my 700. Ran one wire from the stock battery with a 25A fuse right at the battery, to the front where I mounted the Duracell. All accy run through the exact 100A breaker shown above, and then they each have a fuse feeding them.

The batteries are seperated by a blue sea mini ACR. I also have a voltmeter built into the USB like toggle switch, so its real cool to watch the Mini ACR work.

12.4-12.6V everything off. Start the pioneer and within 10 seconds the voltmeter jumps to 13.8V-14.0V. Left my satellite radio and MTX soundbar on for 3 hours and the meter was down to 11.6 I think. Started right up, jumped to 13.2 and quickly worked its way back to 13.8-14 V.

Love the set-up.

Nothing against one big one, but I looked, thought, looked hard, and just didn't like the exhaust/heat right in that area, and had plenty of room up front for the Duracell.

Tough to see in the pics but I bent some flat aluminum for the battery holder. It has another U shaped piece under the battery going left to right to keep it side to side. Lined it with foam tape. For now. it has a large velcro strap all the way around it, and after one weekend, it hasn't budged.

Where the two screws are in the aluminum now resides the circuit breaker. This pic was 85% done but not cleaned up.
