In the power tool batteries, lithium batteries are a meeting composed of many cells, such as lead-acid batteries and many other battery types. This is likely to make the minimal voltage of a LiFePO4 12.8V. Eight cells attached in a string create a 24V battery with a nominal voltage of 25.6V and sixteen cells connected in a string create a 48V battery with a nominal voltage of 51.2V. These voltages work very well with your typical 12V, 24V, and 48V inverters.
Lithium batteries are usually utilized to immediately replace the lead-acid batteries because they have very similar charging voltages. A four cell LiFePO4 Battery (12.8V), will typically have a maximum charge voltage between 14.4-14.6V (depending on manufacturers recommendations). What's unique to your lithium ion battery is that they don't require an absorption fee or to be held at a continuous voltage condition for significant intervals. Typically, when the battery reaches the max charge voltage it no more needs to be charged. The discharge characteristics of LiFePO4 batteries is also unique. During release, lithium ion batteries will keep a much higher voltage than lead-acid batteries typically would under load. It's not unusual for a lithium battery to only shed a couple tenths of a volt from a complete fee to 75% discharged. This can help it become hard to tell just how much capacity has been utilized without battery monitoring equipment.
