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.
Our lithium cells together with our Battery Management System (BMS) create the safest
lithium battery on the market, with more starting power, and longer life.
The common features of our Lithium Batteries;
• Flexible battery connection – with center mounted terminals and terminal adapters,
the same batteries can be used in either left or right side polarity applications.
• Longer Storage Life –there is no need to float charge in the off season
• Environmentally Friendly – no hazardous chemicals and it can be recycled
•
Fast Charge – can be fully charged in less than an hour (if charged at the maximum
recommended charge rate)
•
Maintenance Free!
•
No Special mounting direction (could even be mounted up-side-down)
•
Will Not Freeze or Boil Over – Lithium batteries are dry cell technology and will not
freeze or boil ever
Failure to follow all application use, installation, charging, and storage instructions may result
in battery damage and or fire!

Technology Inside

Battery Cells

Our batteries use cells made of Lithium Iron Phosphate (LiFePO
the highest performance and safest on the market today.
Lithium batteries are fundamentally different than lead-acid batteries. A lithium battery
voltage remains relatively constant while discharging, while voltage for a lead-acid battery
decreases. A lithium battery's storage capability is nearly 100% usable (measured as Amp-
Hour, Ah); while a lead-acid battery designed for motorsports typically only has 30% useful
storage. As such, 2Ah lithium battery has the equivalent "useable" capacity to a 6Ah lead-
acid. Also, a lithium battery's cranking power is stronger, for the voltage while cranking is
generally higher. But when the lithium battery runs out of power it does so more abruptly.
LiFePO cells by the nature of their chemistry are 3.3 volt. 12V lithium batteries are created

by using 4 cells in series (technically it is a 13.2 volt battery, but nominally full charge voltage
