| Hey again guys Right as you lot know i have myself a Classic mini 1979 and the battreys are pants on them i know for a fact you can stick a pug 306 tdi battrey in them and they are good as they are heavy duty battreys (i have one in) But I want more juice!!!! ive had a quick google browse and i know its possibal to connect two battreys up with an isolator?! will quite simply an isolator switch work? ie you have one battrey for your starter moter connected to isolator switch then you switch that over to your accessorys (seconed battrey)? and let the altonator charge it while the other one is in use? is that how it works im getting real confused about this? i have a wiring digram but im confused about the isolator can a switch work or does it have to be a device?

| Hey there i know alot of you guys have viewed the post and yet no one has replyed, i went to the audio shop today and asked about two battreys for what i need it for, d2400 amp with orion 10"hcca with a focal k2 system and 4channel amp, for this i could run it off and 1upgrade from my exsting battrey and hope that my autonator will still charge it, they really wouldnt recomened sticking two battreys in it i know there are 3ways of doing so, 1 parrell (two battreys wire from + to + and - to -) (Really strains your autonator) 2 Relays (one battrey goes flat while it charges the other one , Kinda pointless) 3 Isolators (Really expensive, hard to find, does same thing as relays really) all day long they said stick to bigger and better battreys and if you can upgrade your auto to get the power!!!!!!!!!!!!

| In a car audio forum I frequent, there are allot of users there that do not use an isolater or regulator. With two batteries you should be OK. Just charge them over night to keep them charged up also look into BATCAPs.

what one dies when the other charges? um no!!
Battery Isolators, Automatic Charging Relays (also called ACR’s , combiners, or voltage sensitive relays) are all intended to keep a load (or loads) from discharging the reserve battery system. The reserve battery system is used for vital loads like engine starting, navigation or communications. Battery Isolators and ACR’s are intended to distribute current from a charging source to all batteries, but leave the batteries isolated during discharge conditions so they are only impacted by their own loads.
Battery Isolators are made with two or more silicon diodes that act like check valves. The diodes will pass current from the charging source to the batteries, but will not pass current backward from one battery to the other or back to the charging source. Nature extracts a price for this by causing a voltage drop of about 0.7 Volts across the diodes. If you have a regulated charging source that senses its own output, the voltage at the battery will be lower than at the charger or regulator and, if not compensated for, will lead to inadequate charging.
ACR's or Automatic Charging Relays are automatic switches that close when the voltage on one of the batteries rises to a level (normally 13.2V to 13.7V) indicating the battery is connected to a charge source and is partially or fully charged. The switch then closes and shares the charging current with the other battery until the voltage drops to some lower level (normally 12.4 to 13.1 depending on model) and the switch opens. This prevents discharging both batteries when there is not enough current to charge both batteries.
With the ACR or an isolator, the batteries are effectively connected together during charging and disconnected during discharge. The isolator is the simpler of the two approaches, when used with remote sensing chargers and regulators, but without remote sensing the isolator gives poor performance.
The ACR simplifies the system design because chargers and regulators that work with a single battery bank will still work with a multiple battery bank. Outboard motors and inverter / chargers have a single line that provides charge current, but can also absorb starting current or inverter current. They can't be connected through an isolator because the isolator will not permit the backward flow of energy when the source becomes an intended load.

what ya need is a higher amperage alternator and a 2 farad cap and be done with it, and ground the engine with a lower gauge wire to get what u can from the charging system . a higher amperage alt is better than dual batts cause the alyt wil have to charge 2 batts( double the charging load as the alt sees it)

Hey there thanks for the reply, yeah im gona stick out with buying a upgraded battrey for my car, hope itll charge and support my orion amp and sub, if not then changes will be made ill upgrade my auto, and stick a power cap on it, see how well that performs, to be honest it should work perfect i mean i dont have many eletrical things running, i have my amp my headunit, lights and wiper, no heater system or anything! 
Thanks tho guys!

| well, i'm an orion old school lover, i am sure MBR70 suits you the most. you can add up to 2 extra batteries. It's no longer available, you can try your luck in ebay.
