Generally, people install Lead Acid Batteries in their Recreational Vehicles and Boats to run the everyday Habitation\/House services.<\/p>\n\n\n\n
There is increased interest in Lithium Batteries (and particularly the LiFePO4 style of Lithium) as they offer various benefits and advantages over Lead \u2013 however up-front cost is definitely not one!<\/p>\n\n\n\n
But what about the idea of using both at the same time, maybe taking advantage of both Lead and Lithium at the same time? Wouldn\u2019t that be cool if it were possible? Well, maybe it is \u2026.<\/p>\n\n\n\n
This is a discussion about the concept of having a Hybrid Bank comprised of both Lithium and Lead Acid batteries, broken down into a number of hopefully logical sections in different posts to make it more manageable to read. The following is a brief description of what to expect in each part and a quick link to each one if you want to skip to a specific area<\/p>\n\n\n\n
A Lead Acid Battery when fully charge tends to settle at a voltage of around 12.8V. As the battery gets used, the voltage drops in a very linear fashion.
A Lithium Battery has a very different voltage\/Amp-hour pattern. The Lithium Battery\u2019s voltage is pretty flat until it gets to a fairly high Depth of Discharge (DoD), at which point the voltage drop starts to increase and when the DoD starts to get close to 100%, the Voltage really drops away and maybe the Lead Acid would start to come into play?<\/p>\n\n\n\n
So based on just the mathematics of Voltages and comparing the two sets of numbers, would a Hybrid Battery work? <\/p>\n\n\n\n
Ok, time for some pretty pictures now. <\/p>\n\n\n\n
