For the people who run multiple batteries

Silver Member Username: BernymacRialto, CA United States Post Number: 355 Registered: Sep-04 | What do you guys do? I know about the fusing part, but do you guys use battery isolators or do you guys connect all batteries together? Like front + to batt 2 + then batt 2 + to batt 3 +? And then ground the extra two batteries to the car chassis? Thanks if anyone can give me any input. I have one red top in the front and two odyssey batts for the back. |

Silver Member Username: JohnfiacIL USA Post Number: 503 Registered: Mar-06 | i did the same as chad.. no isolater.. u dont want to do it in series or your voltage is gunna be high (+ from one batt to - on other battery) you will fry almost every amp on the market, maybe all of them but i think i seen a 24V amp somwhere |

Silver Member Username: RenegadesrunLafayette, IN US Post Number: 192 Registered: Oct-04 | No isolator. If you dont wire it this way, they will charge in an overflow, instead of a "bank". Ground the front batt to frame AND the rear batt. Same frame rail please. Diagrams of how to do so will be linked to below. My ghetto rodeo install, and wiring diagram are here. http://www.splbassx.com/forums/index.php?showtopic=8192 |

Gold Member Username: Extrmndor3Chicago, Ill Us Post Number: 2021 Registered: Feb-06 | if u have a renegadesrun its better to run an extra 0 gauge wire to the battery - and keep the connection to the frame it will help ur voltage to stay and not to drop like hell plus ull have a better ground |

Gold Member Username: CarguyPost Number: 5680 Registered: Nov-04 | For optimal setting, you SHOULD get some kind of isolator. This will insure that your car will ALWAYS have enough power left for starting. If you connect 2 or more batteries, make sure they're identical in size. Picture C and D sized batteries in parallel. You would never do that. Same theory applies with car batteries. |

Silver Member Username: RenegadesrunLafayette, IN US Post Number: 211 Registered: Oct-04 | I ran the Rodeo for 2 years with no alt and 3 Kinetiks, then 4. Driving to and from comps, even long distances. Daily driving. PLUS competing. No isolator. Didnt need one. No alt. Never dead. Moral? Watch your voltage. Well that and newer Rodeo's have no room for large case alts. |

Gold Member Username: Extrmndor3Chicago, Ill Us Post Number: 2022 Registered: Feb-06 | not u never get an insulator why the insulator its a terrible thing because make your voltage drops and who wants that??? if u dont beilve ask iraggi alternator every high output alternator that u get from them they tell u not to use insulator ask others like excessive amperage if u dont beilve me |

Silver Member Username: JohnfiacIL USA Post Number: 523 Registered: Mar-06 | isolater = easiest way to explain.... say u have power supply a and power supply b, both they both charge from power supply ALT (the alternator) A being the battery under your hood, and B being any battery running your system, A is just like a completely new circuit that has not connection to power supply B's output, A and B are seperate outputs on different circuits, so when you system kills all your power from bumping with the car off... the starter battery will still be completely charged.. |

Silver Member Username: BernymacRialto, CA United States Post Number: 359 Registered: Sep-04 | Thanks for everyones reply. But I did understand the Isolator setup. But I also wanted to know other ways I can do it. I never play with my car off anyways. The only time I play my system is when I drive. But I might consider entering a few competitions to try to atleast get some trophys =). |
