    Battery discharge

    I have just the single battery and noticed that after a couple of days camping that the battery was down to 53%. I didn't take any power from the vehicle, maybe opened the doors about 10 times per day. The internal light was set Auto off. It would have been good to have had some kind of mode...

    50Ah LiFePo4 Battery Installed

    Hi, This is what I've worked on the past 3 days: I used the DS250SE to manage the LiFePo4 battery, and left the initial vehicle configuration intact (the two batteries managed only by the smartpass 120): This is the battery that I used...

    Confusion with battery management

    Unfortunately, I still don't understand it and can't find it clearly in the articles: The SMARTPASS 120S disconnects the starter battery from the service battery when the engine is not running. When the PWR switch is switched on, is the power drawn from the socket in the load compartment from...

    "False" Battery Percentage displayed!

    I have the dual battery installation (Trialmaster). Since ownership the battery % has never shown more than 75%. I disconnected both batteries a couple of months ago and the percentage then jumped to 92%. This situation only lasted a few days before reverting to 69%. Now percentage shows 69%...

    Battery died in 2 days under strange circumstances - engine and airbag lights on

    Hello dear friends! This is the first problem I have with the car and therefore also my first post on this forum. I own the diesel trialmaster with an auxiliary battery. So three days ago I went for a drive to my local car wash. After starting the car I noticed I was not able to connect my...

    Auxiliary battery and fridge

    I am picking up a new Fieldmaster in a couple of weeks. It has the auxiliary batter. I’m looking to add a fridge/freezer (Dometic CFX3) in the boot on a slider. Does anyone know if you can attach the unit to the aux battery or do you just use the cigarette lighter socket in the boot? Apologies...

    Auxiliary Battery setup components

    I got my Fieldmaster without the Auxiliary Battery and now I regret that. Is it easy to add that now? What components I need to buy?

    Battery Access and disconnect process?

    Gone through the manual and searched the forum (Battery AND disconnect), and for the life of me I cannot seem to find details that outline the steps to fully disconnect the battery (and aux). The manual simply says : Disconnect the ground connections to the Battery Combiner. Remove the Negative...

    Auxiliary Battery

    I am looking at two models right now... yes, I am approaching "buy mode" very cautiously, still not happy with the price. Can anyone give me an opinion on whether the price difference (around £4.5k) is justified for a factory-fitted winch and auxiliary battery, rather than choosing and fitting...

    Hi toghether First off all I would like to express that I am very happy with the Grenadier - just to start in the right manner 😉😂 Okay that said here comes the topic I need to understand: That the battery drained in the Grenadier is discussed as far as I know. My question is: what is causing...

    Why not change the second battery to Lithium?

    Is it not possible to replace the second battery with a lithium battery and use it as a supply battery? The second battery is charged via the alternator and disconnected from the starter battery by the Smartpas. Or am I seeing this wrong?

    What does this overhead battery switch actually do?

    I cannot find any info on what the switch with the battery icon does. See pic. It does not need to be in the on position for the other switches to power devices.

    Battery at 78% but Grenadier didn't start

    On Saturday I had a ride and drove a small loop in the area. The battery was at 72% when I set off and was then at 78% in the evening. So no problems on Saturday. But when I wanted to go for a ride on Sunday, the engine wouldn't start and the starter remained silent. The control lights were on...

    Build Thread Battery and Roof Rack New Install

    So today I installed the Front Runner 3/4 Rack and a Kickass slim line lithium battery. I did not opt for dual battery because I wanted to do my own thing . I had to modify the seat slider handle and move a connector but the battery fit under the seat. At some point will be putting in the 40V...

    How large of a house battery can fit?

    How big of a volume is under the seat that a battery can fit? I can visually see it obviously but haven't removed to see how much space is there. Would this fit? On another website I found it size to be 13.07x9.52x9.84. I saw where people are putting air compressors in there. I'm not creative...

    Battery system

    It would seem all the electrical outlets for accessories (fridge etc) have their current drawn from the main (crank) battery. I thought that the ctek powerpass automatically enabled the car to be able to crank from the service battery when the crank battery is low ? I read here many people who...

    Key battery empty

    Today I got the information while starting the engine, that the battery of the key is close to be empty. Not a big thing, but I am a bit surprised. After 5 month and only 19.000 km the key battery is empty. Never had that in the last decades. Again, nothing serious, but maybe it is worth to...

    Going Cold Cranking Lithium for both Batteries?

    Hi, I have a thought to replace both batteries with Lithium Cold Cranking replacements - there are a number of people in Australia who have done this with Lithium batteries for other vehicles (myself included) very successfully.

    Primary battery replacement

    I have a battery that doesn’t stay charged above 65%. The battery is however only charging at 1 or 2 amps when driving. I have been supplied a replacement battery under warranty as supposedly a faulty battery. My Grenadier has a factory plastic floor and I was wondering how much of the floor...

    Aux or second battery -

    OK the auxiliary battery is standard on the Trialmaster edition. 1, If you have a Fieldmaster that has had the 'High Load Auxiliary Switch Panel & External Preparation' option added - does this include the Auxiliary battery? 2, If you want to fit the winch - I am guessing you must have the...

    Factory fitted auxiliary battery in the trialmaster

    Battery completely dead - no prior symptoms

    Went to use my car yesterday afternoon and the remote key fob would not unlock it (car had been standing in the garage for three days). Thought it was a bit odd. Changed the battery in the key fob - no difference, still would not unlock the car. Got the spare key (never used from new) - no...

    Auxiliary battery retrofit in UK?

    Custom Dual Battery setup

    I ordered my Grenny w/o the dual battery system, because by the time ordering the specification were unclear. Now, as we know how Ineos designed it, I must say this was the right decision for me. I would feel much more comfortable with a classical setup, i.e.: dedicated sockets which are...

    NATO socket jump start capability

    I remember from my times in military service that via a NATO socket basically every vehicle could jump start another. E.g. a Wolf (military G-wagon) could start a tank with drained batteries. So does the NATO socket in the Grenadier has the same function? Supply power to an other vehicle (or...

    Right. Where is it? Serious question. I've picked up, taken home and left in the garage for a month. Was in possession for 6 hours. Hand book was 1000 pages of infotainment but no diagrams of where things are or how to do. Very different to my 1967 220 Cortina. A photo will help. Anything.

    Battery %

    Within the ‘Off-road’ menu, you can check the state of the battery including percentage charged. Does this the percentage reflect the main engine battery, the leisure battery or across both? I seem to be losing approx 10% of charge over a week of not driving if the system is to be believed.

    Spare battery compartment

    I note that in my SW, the space where the auxiliary battery would go, does not contain a waterproof box that I am sure has been fitted to some vehicles. Could this box be part of the auxiliary battery set-up?

    Americas Dual Battery vs Premium Sound - What to Spec to most easily end up with both

    It would be great to end up with both a Dual Battery and Premium Sound. Since they occupy the same space, it would seem like the best thing to do is to spec the dual battery and then hopefully you can easily upgrade to a premium amp and locate a sub-woofer elsewhere in the boot or a custom...

    Procedure to shift into Neutral with a dead battery (fiddly but doable)

    If your battery is dead and you need Neutral for a tow or a roll or whatever, sounds like a 5mm hex socket and access underneath the truck is required. With the Grenadier's clearance (compared to any other ZF vehicle), hopefully this doesn't mean jacking it up. It's such a common transmission...
