Here you will find the most frequently asked questions and our answers. But first we want to show you the steps that are required to carry out the conversion to LiFePO4.

Steps to replace lead-acid with LiFePO4 batteries

  1. Stocktaking
  • What is the current status of my electrical application
  • What do I currently charge my batteries with?
    • AC-DC charger (shore power)
    • Wind generator
    • alternator
    • Solar system
    • Generator
    • Other
  • How much capacity do I have with my current batteries?
  • Which consumers need how much energy over 24 hours?
  • Which consumers are connected to my network and which max.currents are required if these start up at the same time?

2. Definition of objectives

  • Wie viel Strom benötige ich an Bord (A)?
  • Can I get by with the energy or do I need more energy (Ah)?
  • How long do I want to be self-sufficient?

3. Planning

  • Design of the electrical application
  • Think through loading, storage and delivery
  • Consider financial aspects

4. Implementation

  • Professional installation
  • Calculate the correct cable thickness for the application (power consumption) and the cable lengths.
  • Correct insulation and connector to prevent leakage currents

5. Check, control and maintain

  • Check functionality and efficiency
  • Check tensions
  • Which tools do I need aboard


Here are some of the most frequently asked questions and our answers.

  1. Check all chargers for the LiFePO4 charging (shore power / alternator) for currents.

  2. Make sure that the charger (shore power) is suitable for LiFePO4.

  3. In order to be able to charge both your starter battery (lead-acid) and your consumer battery (LiFePO4) with the alternator, you need a DC-DC charging booster.

Make sure that the DC-AC converter has a sinusoidal output voltage of 50Hz / 230V or 60Hz / 110V for this application.

Yes, but with the use of a charging booster if lead acid and LiFePO4 are to be used at the same time.

  1. Total cost of ownership is much better. The initially high acquisition costs are put into perspective by the longer service life.
  2. Fully usable capacity thanks to more constant voltage.
  3. Less weight
  4. Monitoring via the BMS and the possibility of receiving information about the battery via Bluetooth.

Yes, because a BMS is installed that monitors voltages, temperature and currents in order to avoid damage to the battery.

Yes, but it makes more economic sense to use a lead-acid battery because it is designed to start engines. Due to the high starting currents, your consumer batteries would have to have a very high capacity.

Mostly only a few in parallel in series.

The Super-B Nomia and Nomada can be connected in series.

BMS stands for Battery Management System

It controls the current and voltage and the temperature.
