Upgrading to lithium batteries offers numerous benefits, including greater energy efficiency, longer life and the ability to charge faster. However, switching to these modern batteries in older motorhomes can present some challenges, especially if the existing EBL is not compatible.
Why older EBLs are not compatible
A major reason for the incompatibility is the lack of specific monitoring systems required to fully utilise the benefits of lithium batteries. These systems closely monitor the battery's charging status and performance and are crucial for safe and efficient use.
Another important aspect is that it is usually not possible to replace older EBL models due to the different plug and connection configurations. These can lead to considerable installation problems during an upgrade.
- IBS sensor and AGM monitoring: An IBS sensor is an intelligent battery sensor system that monitors the battery condition and provides important data such as voltage, temperature and battery level. This type of sensor is often used with AGM batteries. With lithium batteries, the IBS sensor can provide inaccurate status displays due to different chemical and technological requirements and lead to constant error messages on the control panel.
- Error display and charging curve problem: An EBL that is not designed for lithium batteries may not charge them properly. Lithium batteries require specific charging characteristic curves that older EBL models lack. This can jeopardise the battery condition and significantly impair its efficiency.
Recommendation
Before upgrading to lithium batteries, it should be ensured that the EBL model is designed for this or can be adapted accordingly. Consultation with a specialist is crucial to ensure the full functionality and safety of the system and to avoid potential problems.
⚠️ Safety note
Current is not to be trifled with - your life could depend on it.
💡 Our tip
If you want to switch to lithium batteries, make sure that your EBL matches the battery type. It's best to seek advice from an expert to avoid any nasty surprises!
