Section 4 - Protecting Your Battery

Lithium batteries cannot be protected effectively by monitoring voltage due to their ability to maintain
a higher voltage for much longer than AGM or flooded/sealed batteries.
"State of Charge" (SOC%) percentage is the most accurate and effective method of disconnecting loads
from the battery - this requires a battery monitor which uses a "shunt" to measure the current going into
(Charging) and coming out of (Discharging) the battery.
Example;
200 Amp Battery
It is recommended that Lithium batteries not be discharged below 20% State of Charge or the battery
life may be shortened.
As an added layer of protection, the Enerdrive B-TEC Lithium Battery also has a built-in low voltage
disconnect circuit. If this occurs, please refer to
