Change from Lead-Acid to Li-Ion batteries
The problem I have on board is the storage of electrical energy. Beside the alternators of the engines and a genset, I have 1kWp solar power and a wind turbine.
I have 5x 100Ah lead-acid batteries for service purposes (engine batteries are separate), from which I can draw a max of 100Ah without damaging the batteries. When charging I have a the first a high and then a very low charging current to charge the batteries without damaging them.
- What is your experience with changing to Li-Ion batteries?
- Can solar panel controllers be replaced for Li-ion suitable ones?
- Is it necessary to also replace the inverter-charger unit?
- To which charging level can Li-Ion batteries be discharged to not damage them?
- What are charging currents and times to reach 90-95% recharging level?
- What kind of Li-ion battery maintenance is needed and how often per year?
- What are other experiences you made when changing to Li-ion batteries?
- What is your experience in using Li-ion batteries?
- What kind of experience did you make with other types of batteries and how much energy can be used without damaging the batteries?
A lot of questions, I know. I appreciate your answers a lot.
