Providing a drop-in replacement for traditional lead acid batteries and AGM batteries, lithium offers a myriad of benefits, including a longer life cycle, lighter weight, and faster charging. When transitioning to lithium-ion batteries in an RV, the charging process is of paramount importance.
To successfully replace lead acid batteries with lithium, there are three main steps to follow. First, select the right lithium battery for your specific application. Next, upgrade the charging components to accommodate the lithium battery. Finally, ensure proper safety measures are in place for a secure and reliable battery system.
Lead acid batteries require a simple constant voltage charge to the battery while lithium ion chargers use 2 phases; constant current and then constant voltage. Unlike lead acid batteries, Lithium-ion batteries have an extremely small capacity loss when sitting unused.
Lithium batteries are a lot more power dense than lead acid or AGM batteries, so this means that a replacement lithium-ion battery of the same capacity will be much smaller than a lead acid battery. So, buying or building a lithium-ion battery for a lead acid scooter is a relatively straightforward affair.
The first step in upgrading a 12-volt lead acid battery to lithium is to choose the cell chemistry and configuration. This is a necessary step because regardless of the chemistry you use, lithium-ion batteries have a voltage that is much lower than 12. This makes it so you will have to put some amount of them in series to achieve 12 volts.
Due to their many advantages across a wide range of applications, it's becoming more and more common to replace lead acid/AGM batteries with lithium. If you are upgrading a home battery bank to lithium and you already have a modern charge controller, the process could be as simple as installing the new batteries and flipping a switch.
A common desire nowadays is to replace a lead acid battery with LiFePO4 in a system which already has a built-in charging system. An example of one is a sump pump battery backup system. Because the batteries for such an application may occupy much volume in a confined space, the tendency is to find a more compact battery bank.
For smaller applications like solar-powered outdoor lights or portable power supplies, you can expect to pay between £16 and £80 for a LiFePO4 battery.
