While over at Dusseldorf I visited a stand selling Li-Fe (Lithium Ion) batteries at about €1800 for a 110 amp unit. That's about ten times the cost of a regular lead acid unit, but it should last up to fifteen times as long. Nissan quote 90% capacity for their LI-Fe batteries in the Leaf after 10 years use.
Other benefits of the Li-Fe battery are a significant weight saving, being less than one third the weight of lead-acid and being able to deliver about twice the power makes one 110 amp Li-Fe do the work of two 110amp Lead Acid while saving about 50kg in weight. Li-Fe also charges quicker and can discharge at a high rate, making them very suitable for running large inverters.
But the price is a real stumbling block.
Have a look HERE, for about €900 or £800 at today's exchange rates 180ah of Li-Fe can be had, which is the equivalent of about 360ah of lead acid, more than enough to the most power hungry motorhome.
If 72ah Li-Fi (140ah Lead Acid) is sufficient for your needs €480 or £430 would do the job.
If a person is going to invest in Li-Fe, buying from suppliers to the electric vehicle and home energy market could represent a huge saving over buying from suppliers into the RV market.
The above is only a lay persons opinion, any sparks out there are welcome to add their professional opinions.
