Adding a second battery.. question!


Recommended Posts

The system I have now is drawing 1200RMS off of a stock battery and 90 amp alt with the big 3 done and im still having some voltage drop and light dimming(inside lights, headlights are HIDs) so my question is, if i added a small Kinetik HC600, would i wire that up with my big 3 wires? Or run new wires from the stock battery to kinetik? and also, would that cause more strain on my alt since it would be pushing two batteries? Im looking at getting a new alt soon, but just wondering how it would effect my old one. and also if another battery would help?

Thanks!

Add it to your trunk by running new wires. Yea, it will strain your alt a tiny bit I think but as long as you charge the bats every once and a while you'll be good I think.

I have a truck and was going to put it under the hood..

No problem. Put it wherever, just add it to your vehicle don't replace the old one. Use them both.

wire all secondary batteries to battery under the hood. the big 3 never should get touched.

Okay, so will a second battery cause more draw on my alt? If so, would it be a positive thing to add a second battery or negative? Would a 120amp alt run everything okay instead of a 90 amp?

Run batteries in parallel, fuse 18" of each battery. With the original battery you did the big 3 on, leave the big 3 be, just run a positive from original battery to second. Ground the second battery to the frame. As of now there is no need to run a alt + to second battery +

Edit: Wth, HID lights should never dim unless there is a huge voltage drop. The ballasts regulate so there is always a constant voltage coming out. iirc
