Trojan Battery Lithium-Ion FAQ Guide Rev 06/20/2022

GENERAL
What is a BMS and its purpose?
Lithium-Ion batteries are made up of multiple small cells connected together to
provide the voltage and current needed for the application. The Battery Management
System or "BMS" is responsible for keeping these cells working in unison so that
they are charged and discharged correctly. Lithium-Ion cells are more sensitive to
overcharge and undercharge conditions than many other battery chemistries. The
BMS monitors the charge and discharge of the battery to ensure the battery operates
safely. For the Trojan GC2 48V Lithium-Ion Battery, Trojan developed a BMS that is
able to monitor individual cells, internal battery temperatures, state of charge, state
of health plus charging voltage and current to provide the safest and most reliable
operation possible.
What Lithium chemistry is used?
The Trojan GC2 48V Lithium-Ion Battery uses Lithium-Iron-Phosphate cells.
My vehicle came with 8V or 12V
batteries, but the Trojan GC2 48V
Lithium-Ion Battery is 48V, what
is the difference?
Most low-speed electric vehicles operate on 36-48V DC, but traditional lead-acid
batteries are designed and built to be 6, 8, or 12V for portability and to make them
more universal. When they are installed into a 36 or 48V application, these batteries
are connected together in series to increase the available voltage to match the
requirements of the vehicle. The Trojan GC2 48V Lithium-Ion Battery is designed to
work with 48V vehicles without using series connections. This provides increased
reliability over configurations that use series connections because each battery can
power the vehicle independently, where one bad battery in a series connection can
reduce the performance of the entire system.
How do you read the date codes
on the batteries?
There is no date code on the Trojan GC2 48V Lithium-Ion Battery. The manufacturing
date is marked on the sticker with the serial number on the side of the battery.
