Inverter Question
Hi D and running the inverter while the motor is running will be fine. Use good thick cable and your inverter will run more efficiently, and that means it won’t get so hot. -

Inverter Question
Hi David and do you have a specific reason for using such a huge inverter? Most people find a 300w inverter will meet most of their needs and even these chew a fair bit of power but your 1600w, if run anywhere near full capacity, would not only pull a huge amount of current, your battery would... -

Stock Battery and Cold Weather
Hi Landmark and another cause of a “weak” battery is your driving habits. How often do your drive and when you do drive, for how long? If your are not driving that often and/or do short duration drives, your battery is never going to charge properly. As overblown suggested, try putting... -

Question for LR4 owners who upgraded from an LR3
Hi jjvd21, my wife went from a D3 ( LR3 ) to a D4 ( LR4 ) and there are quite a few noticeable differences and the style and feel of the D4’s interior is a big jump forward. The ride is better and the sound level is much lower. When the D4 first appeared, I really didn’t think there was... -

Battery advice
Hi Rich, it should start first time every time but anyway, did you get a chance to try charging the battery or has the problem just gone away? BTW have you had any warning messages displayed. I have just had an alternator fail in my RR and got no warning before it happened. -

Hi Rich, did the shop give you a quote to repair/replace your alternator? -

Battery advice
Whether it’s the battery or not, starting like that, taking a few minutes of trying, will stuff your battery, particularly as you are not driving much to allow the battery to be charged back up again. Do you have another vehicle available and a set of jumper leads. If you do, try set the... -

Battery advice
Hi again Rich, your problem is probably the short driving times. If you can’t borrow a battery charge then try taking the LR3 for a good drive and see if it starts easier for the next few days after your drive. If it does then all you need is a small battery charger and give the battery a... -

Battery advice
Hi Rich, first off, do you have a battery charger and what sort of drive times do you do when you go for a drive? -

Which Yellow Optima Battery...
This thread has nothing to do with bickering or for that matter, about my isolators. Just about every claim you have made flies in the face of what happens in the real world. For instance, you claim an alternator can’t provide enough current to charge whereas the facts are that a D3/LR3... -

Which Yellow Optima Battery...
As with any battery, if you don’t have the voltage difference required between the battery's SoC and the charging source, you don’t have current draw by the battery and so even without knowing the voltage levels, the fact the battery was pulling 63 amps proves there was a sufficiently high... -

Which Yellow Optima Battery...
So what were you implying in this claim? We are talking about Optima batteries fitted the LR3s, these vehicle produce around 45+ amps at idle and well over 100 amps when cruising. Just how many amps do you reckon is needed to charge a 55Ah battery. During low voltage stating tests, after... -

Which Yellow Optima Battery...
Then once again, where is the smoking gun. What you are claiming is just not happening and in the case of those using my gear with an Optima for their auxiliary battery, are actually get the reverse happening. Quite a large number of D3, D4 and RRS owners have reported that while they have... -

Which Yellow Optima Battery...
Having loads of experience in a given field still doesn’t correct the fact that you have it wrong about paralleling batteries, and we are talking about batteries in vehicles not batteries in RAPS or UPS set ups, which will have totally different charging regimes. We are talking about charging... -

Which Yellow Optima Battery...
MilehighLR3, for someone so self acclaimed in this field, how can you make such a fundamental error of mistaking the requirements and limitations of wiring batteries in series as being the same for wiring batteries in parallel. There is no such requirement to wire identical SIZED batteries in... -

Which Yellow Optima Battery...
Well MilehighLR3, I can only comment on what I have found from 20 years of designing and manufacturing Dual Battery Controllers and systems, and I have never come across a problem when paralleling different battery types that you would not find when paralleling identical battery types... -

Which Yellow Optima Battery...
Hi MilehighLR3, and sorry mate but this is just an old wife’s tale. Many people get the requirements for wiring batteries in parallel mixed up with the limitations involved when wiring batteries in series. With the exception of batteries being used in ultra high current applications, like... -

Second Battery Installed in LR4
Here’s a tip, do not connect anything to the negative terminal of your D4’s cranking battery. You can connect to the positive terminal as in ndrenfro’s picture, but absolutely nothing should be connected to the neg terminal. The reason is that there is a device connected between the... -

Second Battery Installed in LR4
Hi CUCO, make your connections at the auxiliary battery’s positive terminal and the negative connects to the earth post on the inside of the guard in the auxiliary battery compartment on the driver’s side. You can then rewire the cigarette power socket in the rear cargo area to run off the... -

CNET review of the LR4
Just goes to show what can happen when you let a moron do video clip. The differences between an LR4 and a BMW is like compering a quad bike and a tricycle. Sorry but that was a waste of time. -

Aux battery
Hi Joe, as long as the control for the isolator is voltage sensitive, the system will be automatic. With an automatic set up, there is no need for any form of time delay and a 9 minute time delay is actually counter productive. The D3/LR3 alternator is well and truly big enough to be able... -

Second Battery Installed in LR4
Thanks for the pictures ndrenfro. I can see a slight lengthening of the two positive cables going to the battery's positive terminal would make the installation a better finish. In right hand drive vehicles, we have the positive terminal at the rear of the battery box but from your... -

Charging batt w/ trickle charger in Cold Weather / also brake light bulbs
You need to test the battery with the motor off and preferably at least 12 hours after the motor was last run. With Calcium/Calcium batteries used in D3s, measuring after 12 hours, any voltage above 12.5 is a near fully charged battery and anything above 12.2v will indicate the battery is... -

Charging batt w/ trickle charger in Cold Weather / also brake light bulbs
Hi nashvegas, if you want to hook up a battery charger of any type, turn the ignition off remove the key, apply your parking brake and then wait till the parking brake light goes out ( anything up to 3 minutes ). While your waiting for the light to go out, take the cover off you cranking... -

Anyone have the Traxide Dual Bat kit?
Hi folks and a Merry Christmas to you all and please forgive me for not visiting this forum for a while. I make the SC40-LR dual battery controllers and while I’m not out to spam the site, I would like to clarify a few quires posted in this thread. The SC40-LR controller has a constant...
