iceman88 Posted October 12, 2007 Report Share Posted October 12, 2007 I have a optima Yellow top Battery, and a stock battery, i was reading about how to do split charge and then i found out that you could wire them in parrallel. Is this safe to do? and how basic is it? Do i just run a Positive cable from the fron battery and then run wires from the optima in the back to the amps? what gauge wire would i need? currently got 2 runs of 4 gague for my amps coming from stock batt. i have the stock battery under the hood and planning of putting the optima yellow top in the boot, please would any one care to explain as to how i would go on about doing this? thanks alot! thank you in advace!

andym85 Posted October 12, 2007 Report Share Posted October 12, 2007 yea, u just run positive to positive from the front to back battery (with a fuse at both ends, preferably, within 18" of each battery)....u can also run the grounds from front to back, or u can just ground each battery to the frame and no fuse is needed with the grounds (i personally run the grounds from the front to the back)...as far as the gauge of wire,i guess it depends on how much current ur pulling....the bigger the better imo...4 gauge is a good start...i would personally do 1/0 gauge cause that leaves room for upgrades Quote i likes me some audio stuff...

dmanson Posted October 12, 2007 Report Share Posted October 12, 2007 it's recommended that you keep the batteries alike but people get away with disalike batteries all the time.

littleitaly1990 Posted October 12, 2007 Report Share Posted October 12, 2007 I'm wondering the same thing since I don't quite have the money for two just yet. Quote A vitrolic, megalomaniacal sadistic psychopath. Link to comment Share on other sites More sharing options...
bassINyoFACE Posted October 12, 2007 Report Share Posted October 12, 2007 the only reason your supposed to have the same batts is so your alt will charge them all at the same time with the same current and voltage. different batts = diff amps mang. no big deal though just do what you can for now and start saving for more later.

iceman88 Posted October 12, 2007 Author Report Share Posted October 12, 2007 thank you very much guys, anything i should look out for while doing it? I'll be doing it over the weekend, i'll keep you posted about the result! Quote Link to comment Share on other sites More sharing options...
Coolwazabi Posted October 12, 2007 Report Share Posted October 12, 2007 i heard if you mix batts all the batts act like the weakest batt.. Quote Link to comment Share on other sites More sharing options...
kingsuv Posted October 12, 2007 Report Share Posted October 12, 2007 To an Extent , yes. The weakest battery is just that, weak. The newer battery will try to charge the weakest battery and in turn will equalize to each other. Other things to do. FUSE THEM! Quote Designing, building, and shipping boxes.

I mean the first minute is ok but that thing just really starts digging deeper and deeper in your earhole till you cant stand it no more. Seems like it does it with relative ease....16 12's on 8 amps.........gotta love it. Link to comment Share on other sites More sharing options...
bassINyoFACE Posted October 12, 2007 Report Share Posted October 12, 2007 (edited) not really all weak. it's just that the strongest and highest amperage batts won't ever get fully charged and the smaller amp batts get overcharged to a degree due to their lower current resistance Edited October 12, 2007 by bassINyoFACE Quote I got banned for being an ignorant ass....and im a dickhole i like men, michael jackson and large sausages Link to comment Share on other sites More sharing options...
