I have no way of knowing the exact number of lithium batteries in service in vehicles around the world, but it probably runs into the millions (motorcycles, ATVs, snowmachines, aircraft, etc.). Everybody that I personally know with an experimental aircraft is now using one. If weight is important and you are willing to take the time to do a little "battery learning" there is really no logical reason not to use an EarthX lithium aircraft battery. Additionally, it is my understanding that Rotax now officially endorses the use of EarthX batteries (ADMIN please correct me if I am wrong about that).
