A summary of the benefits of powering your motorhome with lithium batteries

The gadgets available for a motorhome seem to never end. However amongst the many items that come and go, some quickly become adopted and become a standard feature. For example LED lights or more recently solar panels. How do some of these accessories make that step from just a gadget that makes life a little more fun or simpler, to something that is a must have fixture? 

Well, we've put together a list of benefits and reasons why adopting lithium motorhome leisure batteries to this list could be a good idea.

Motorhomes traditionally had lead acid batteries based on research discovered over 200 years ago. In contrast, Lithium phosphate batteries are based on research discovered as recently as 25 years ago. Old technologies have many negative issues which must be accounted for. For older lead batteries these include their efficiency, their loss of charge and, notwithstanding risk of explosive gas and safety. These issues are all abolished with lithium-ion phosphate batteries.

Lithium-ion benefits

There are a myriad of reasons to use lithium-ion batteries in your motorhome instead of lead acid and here are some important ones:

  • 50% lighter
  • 2x more capacity (100Ah lithium comparable to 200Ah lead capacity)
  • 4x energy density (400Ah lithium comparable to 100Ah lead capacity)
  • Can charge 10x faster
  • Life span up to 10x longer
  • Integral battery management for safety and correct operation
  • Removes the risk of dangerous gases, fire or explosions
  • Happy to be left partly charged
  • No storage maintenance including trickle charging
  • Discharges safely to 100% without damage
  • 5,000 cycles or more of charge and discharge (over 10 years)
  • No ventilation means no draughts
  • Doesn’t lose charge when stored for long periods, even in cold conditions.

We do of course understand a lithium-ion battery is a costly purchase. A KS Energy 100Ah battery has an RRP of £695. But with an average lifespan exceeding 10 years you will end up spending the same sum over this period for a less reliable and usable leisure battery, is that really worth it?

There are already considerable restrictions on the use of lead and its disposal due to its toxic effect on living organisms and human health. Taking into account environmental considerations, it is expected that the manufacture and use of lead-acid batteries will be increasingly legislated against, to the point where restrictions on their use will mean all motorhomes will eventually have to adopt this superior technology.
