  • Page 3: Overview

    B A T T E R I E S Overview EarthX Lithium batteries are designed as a maintenance free replacement for the 12-volt lead-acid or lithium batteries. To ensure a smooth replacement process, our batteries are similar in dimensions to many OEM motorsport or power sport batteries. Our 12V replacement lithium battery consists of 4 Lithium Iron Phosphate (LiFePO4) cells in series and one or more in parallel with built in electronics to protect the lithium cells.

    ETZ-Series - BMS All EarthX integrated BMSs continuously monitor each cell’s voltage as part of the cell balancing and over-charge protection. If the voltage of a cell exceeds the others, the BMS circuits will work to reduce that cell’s charge level. This ensures that the charge level of all the cells remains equal, even with the high discharge (>...
