Well yes they say you can do it, but they also say they don't recommend it and that it will shorten battery life !!

I will be pushin up Daisies by then , If I dont sell the van tumorra now that diesel will be $5.00 a litre with the new china party in charge ...!!!

The thing everyone feared would happen, when Dometic bought out Enerdrive, compromises would be the result, and here you see an example. They do point out that you will be compromising life expectancy and this is not the ideal way to do it, then they make it clear that the system max current is still only the ability of one battery to deliver, so full marks to them for that piece of understanding. Unfortunately, even though the connection system they recommend will work with two batteries in parallel, people will still read into that even more batteries can be linked in parallel using this method and unfortunately that is a wrong assumption. We have an A Van here at the moment that tried to link 3 batteries in parallel using this method ..... and after 4 mths the whole lot has fallen over.
We have spent a week so far trying to recover the batteries and now we are in the process of attempting to get them to work together rather than the one battery being drained till it shut down, then the next and finally all three batteries reaching shut down, yet the reverse doesn't happen when recharging, this results in all three batteries ending up very close to the shut down voltage/capacity because none of them reach the voltage required for cell balancing to take place ......

Shoulda bought an electric one eh As for how long before problems start to appear, you might still be above the daisies ....... This job we are doing now only last 4 mths before it was on its last legs .....

You can try I'm guessing it would be like suing a politician for not keeping their election promises
I reckon they covered their butts in the first statements in the video, if you go ahead and join the batteries in parallel and they die prematurely, they did warn you eh

So WTF do I do now ...???

As they are lithium batteries, do you need 400Ah?

Have to suck it and see I spose, was gunna go compressor 12 v fridge, induction cooker, 10 ltr 12 ,240 volt water heater ,roof top AC (12 volt or Harrier 4?) Diesel heater ... No LPG , 40 DC to DC charger, 2000 inverter ... solar ...??? if the alternator cant cope ...

Forget about the 12v fridge and get an inverter 240v household fridge that fits where you want it to go, it will use less power and give you better result.
Next is the air cond, probably the roof top inverter unit like the Harrier is the easiest to install, otherwise a split system so the outside unit can be mounted some where other than the roof. That way you have more area available for solar.
The inverter capacity might need to be more than 2000w if you want to go full electric.

As far as the Enerdrive batteries, even though it upsets the powers that be at Enerdrive ( I thought the local rep was going to have a heart attack when we told him what we did to the last one ) we can reconfigure the 12v 200Ah batteries to 6v 400A batteries, then they can be connected in series to make one 400ah 12v battery.
What battery monitor do you have? Is it the Enerdrive Pro what ever? And was it set up by Enerdrive?
If it was, itwill need to go back to Enerdrive so they will remove the locking password from the battery monitor so it can be rest to the correct battery capacity etc.
