Every Firelinx module comes standard with a Lithium-Polymer (LIPO) battery with a short circuit and charge protection built-in for safety. While the batteries are sized to stand up to a long day on site, they do wear out over time. The normal life for a LIPO battery is 300 charge cycles or 2-3 years.
If the battery is failing, this battery can be swapped with a new replacement. All Firelinx modules also have the option of adding a second battery for an even longer life on site, and these batteries can be plugged into the circuit board to extend charge life. Note: Secondary batteries cannot be installed if an OPN expansion board is installed.
