Making room for a 2nd Battery
Jan at Viking has been pushing a 2 Battery System for the Viking Engine. He has also been pushing the Shorai LFX24A3-BS12 Lithium Battery and has a link on his web site because they are light and 2 of these batteries are lighter than 1 Odyssey Battery. Now that I know what the difference is between a Aircraft and Auto engine is, I see why he is wanting 2 batteries. He went to the trouble of making 2 ECUs and 2 Fuel Pumps for the Viking, but without the 2 Magnetos and 2 Spark plugs per cylinder of an Aircraft Engine, the Viking relies on the 1 Alternator to power the 1 spark plug per cylinder and if the Alternator or drive belt goes the batteries run the Spark Plugs till the battery goes dead. With a 2nd battery, you have more time to find a place to land. I already had the Odyssey PC925 which was expensive and I did not want to NOT use it to get the 2 Shorai batteries that Jan was pushing so I got just one and used mine too. I had to drill out the rivets holding the angles that held my one battery and rearranged them to hold 2 batteries. Luckily although the Shorai battery is smaller than the Odyssey PC925, They are the same width, so they sit next to each other nicely. The Shorai Battery came with some nice adhesive backed foam pads of different thickness and size in the box it came in which came in handy to cushion the bottom and between the batteries.
