DUAL BATTERIES ON THE T/D 100 SERIES

Hi Brooka

You need high torque for the diesel.

You have two options.

Fit 2 heavy duty batteries with an isolator. Redarc or ABR unit.

Fit a 3rd battery. Kits are available.

Let me know what you need to run.

I had the same query - ran it past the team at Lcool100 - they suggest that the stock factory setup is two medium batteries wired parallel (no controller between) - just like a big battery but in two halves (guess it aids weight distribution). Seems if you want to convert the second one to an auxiliary function, via a controller of some sort, the primary unit will be probably be too small. Upgrade of the primary at least, seems certain.

The original twin batteries in a TD100 are to give more power for starting & running the cars electrics, not for additional assesories as such.
There is an option Brooka that is ideal for the TD 100. Replace both batteries with 2 x 130AH deep cycle or AGM batts leaving them wired in parrallel. With 260AH you have enough power to run a car fridge & lights for at least 3 days & nights with plenty of reserve to start the engine. To avoid running the batteries flat you could wire all assesories through a relitively cheap low voltage disconnect switch set to cut out around 40%. This system does away with an expensive isolator all together, a device which in the wet, dusty & hot confines under the bonet seem to fail on a regular basis.
Not only does the starter crank the engine over much faster, this system ensures no one battery running assesories is deep discharged below 30% & both batteries charge up together evenly resulting in a long battery life.

Hi Brooka, just wish to mention, depending on the year of your LC (if still under warranty), if you split them, I've been told you will null in void your new car warranty. I'm going through the same issue at the moment, so what ever you come up with, I'd sure be interested in chatting. I do like the sound of upgrading the standard batteries, but this would incur a rather larger bill. The 3rd battery through ARB, seems to be quiet small (55 amp). The only thing l have come up with so far, is to buy a gel or dry cell battery and mount it in the car. If you could email me in the way you go about it, l would appreciate. thanks

From my recollection there was no definitive answer on 100sCOOL however there was one suggestion in was for the colder climate countries.
In any case I have put a 100AH AGM in th rear, charged through a Pirahana isolator and hooked up to 4 fused 16amp sockets and a 300W inverter.

2 batterys are deffinitly not needed to start a turbo cruiser as they run lower compression than a dunger 1hz with one battery and the same donk in the TD 79 runs off one battery. I believe you need to change some wiring and fit a couple of decent batterys with a seperation system - no worries

Thanks to all, I will keep you updated with what I come up with.
