Converting to LiFePo4 batteries is associated with many advantages. Nevertheless, there are a few points to consider to ensure that the power supply to your camper and the devices installed in it is also optimised with LiFePo4 batteries.

A comparison of the manufacturer’s specifications for both the battery and the connected devices is the first step in assessing whether the conversion is possible in your vehicle.

The right energy management is a decisive factor for the correct function of the Truma devices.
Here are the most important points:

• Current output: The sum of the maximum current consumption of the devices operated simultaneously must be taken into account.
  With a Mover XT, for example, approx. 150A; Combi D up to 40A in the start phase; Combi D next generation up to 80 A with current peaks for a few milliseconds (peaks).
  The vehicle-mounted battery must be able to provide this power output, otherwise functional restrictions must be expected.
• Charger: It must be ensured that the charger/alternator used is suitable for use with LiFePo4 batteries.
  • Charging characteristic max. 14.3 V:
    This corresponds to level “AGM 1” for most chargers, alternatively level “Gel” can be used.
• Solar power regulator: Due to the upstream electronics (BMS), some LiFePo4 batteries cannot buffer excess voltages, so a buffering option must be created here for solar systems.
• Battery connection: not only the battery must be able to deliver the power, but also the cabling. Ensure a sufficient cross-section (min. 35 mm²) and correct cable connections. A bottleneck, e.g. a cable taper or unsuitable connection cable at the battery terminals, can prevent sufficient current from reaching the consumer.
  A clean earth contact must also always be ensured to prevent undervoltage at the consumers.
• Low temperature charging: As LiFePo4 batteries behave differently depending on the temperature, a warm installation/charging location is preferable for winter camping. Some batteries have a self-heating function. The optimum operating range is 20-40°C. Charging outside this range will affect the maximum number of possible charging cycles.

Note: A general statement on the use of LiFePo4 batteries is not possible due to the variety on the market.
The Truma product portfolio does not include batteries or rechargeable batteries for powering vehicles. However, as the vast majority of our devices are connected to the vehicle electrical system, there is of course a dependency on these.
From previous discussions with customers, we know that there are some uncertainties about LiFePo4 batteries. We have therefore decided to give you our assessment of this.
If in doubt, please always enquire with your dealer and refer to the highlighted first paragraph of this article.

Hello everyone,

From the past, you are used to being able to comment on our articles and thus enter into direct exchange with us.

To ensure that all enquiries can be processed in a high-quality and timely manner, it is important to use a centralised channel for enquiries. We have therefore decided to deactivate the comment function in this service blog for the time being.

You can use our contact form Customer service (truma.com) to post enquiries or feedback. Detailed information is requested in advance, e.g. the serial number of the unit. This enables us to process your enquiries even more efficiently and quickly.

We would like to take this opportunity to thank our community for their constant friendly interaction with each other and with us.

Your Truma Team

PS: We will gladly continue to create articles on current topics for you so that you are always up to date.

Finally the time has come. The seasonal number plates take effect. You can bring your vehicle out of winter storage or even finally inaugurate your brand new vehicle.

The best thing to do is to check all the installed equipment in good time, so you can prevent delays to your journey.

We show you which points to pay attention to so that the much-deserved start of your journey goes really smoothly.

Truma appliances:

• Replace the air-conditioning filters (if fitted).
• Start up the air conditioner for test purposes (if necessary, heat up the interior first, at least 18 – 20 °C).
• Clean the installation space of the heater and the unit itself (vacuum, wipe carefully if necessary).
• Check all water connections and devices for leaks (fittings, combi, therme, boiler).
• Check whether the networked systems still have a connection (app, iNet Box, LevelControl, etc.).
• Make a Mover test run. Does the swivelling on/off and the movement work?

What to do if a malfunction occurs?

• Find out from reputable sources if there are measures you can take yourself. Feel free to do so via this blog, as well as our homepage and YouTube channel.
• Contact your dealer or one of our service partners. These can be identified by the tool icon in the dealer search.
• Contact Truma Service directly.
• Allow sufficient reaction time to be able to rectify a fault.

What if you want to buy additional accessories or a spare part?

• With the exception of the coolers, Truma does not offer its own shop.
• Therefore, contact your dealer or one of our authorised dealers. These can be recognised by the Truma icon.

Entire vehicle:

• Put the entire gas system into operation. Are the cooker, fridge, etc. working?
• Clean the water system, i.e. the fresh water tank and all appliances with a water tank. We recommend using citric acid for this purpose.
• – Make sure the battery is in order and fully charged (12V power supply).
• Checks tyre pressure and condition
• Look at the vehicle as a whole (lighting, validity HU)

Camping is on everyone’s lips, the industry is booming.
The demand is high, the supply is growing.

Unfortunately, the money that can supposedly be made quickly has led to a number of black sheep jumping on the bandwagon, in addition to many qualified dealers.

Free riders sell products under our name that are not original Truma products.

We will therefore show you today how you can recognize original Truma devices.

• the type plate: each of our products is provided with a type plate at the factory. In addition to information about the device, you will also find the manufacturer’s details and legal identifiers (e.g. CE):

• the Truma logo: 70 years of company history is also symbolized by our Truma company logo. This can be found on each of our devices. Sometimes printed, sometimes glued on. But always easily recognizable.

• Our outstanding service: For Truma original products, you receive a manufacturer’s warranty of 24 months in addition to the statutory warranty. In addition to our service partner network, we offer telephone support and mobile service technicians throughout Germany.
• quality: Truma stands for quality and reliability, for transparency and information. Our official homepage www.truma.com is maintained with a lot of information for you. Product information, product pictures and contact details for us and our dealers and service partners can be found there.

Please feel free to contact us if you have any questions or uncertainties.
