High capacity, fast charge absorption, low weight and at least three times as many charging cycles as a good lead-acid battery - lithium iron phosphate batteries are ideal consumer batteries on board. Especially since the voltage and installation dimensions are compatible with lead batteries.
The lithium iron phosphate batteries from Liontron are equipped with a battery management system and Bluetooth. Therefore, the charge status can be monitored via the app
Only the acquisition costs speak against the light and powerful technology at first glance. 100 ampere hours usually cost around 1000 euros. The investment pays off over the service life of the battery, annoyingly only if such a battery fails after a short time due to a defect. So far, the lithium batteries can hardly be repaired. Since they are welded into a plastic housing, even a small error, for example in the integrated battery management system, can turn the entire battery into hazardous waste.
This is exactly where Liontron comes in. The batteries, which are manufactured exclusively for the German supplier, are also in a sturdy plastic housing, but can be opened. In addition, the internal structure of the batteries is modular. The lithium cells themselves come from Panasonic and are screwed together. Therefore, defective cells or cell blocks can easily be exchanged. The same applies to the main board with the battery monitoring, it can also be changed easily. Even the integrated Bluetooth module can be exchanged. According to the manufacturer, this covers the most common sources of error.
Liontron grants a five-year guarantee on the batteries and promises to keep the spare parts and cells available for ten years even after a possible end of production.
To date, Liontron has been mainly represented in the caravan and mobile home market and claims to be the market leader there. The batteries are available with 12.8 volts in capacities of 20 to 200 ampere hours, whereby in addition to the standard formats, special designs are also available that fit exactly under the seat consoles of vans and mobile homes. There is also a 25.4 volt series that can be used to replace 24 volt lead-acid batteries.
Liontron offers batteries for 12 and 24 volt systems in different designs. Capacities range from 20 to 200 ampere hours
According to the manufacturer, the batteries are fully compatible with lead batteries and can be charged with the existing charging technology without any changes. A so-called charging booster or battery-to-battery charger (B2B charger) is only recommended for the alternator, since the standard charging characteristics of the generators do not utilize the full capacity of the lithium batteries.
The batteries can be obtained from various camping equipment suppliers or directly from a subsidiary of the manufacturer. 100 ampere hours cost 989 euros.
