Battle Born LiFePO4 Batteries
Note: Any LiFePO4 battery System not equipped with compatible CANbus communication will require mitigation to protect the alternator and other sensitive electronics from potential battery disconnects. This includes the use of an alternator equipped with avalanche diodes, battery protection devices, or a keeper battery. While the WS500 can provide superior charge control for your batteries, it cannot mitigate voltage spikes caused by battery disconnect events.
Developed in Conjuction with the Dragonfly/Battle Born engineering team, these instructions and the accompanying wiring diagram represent a "best practice" approach to charging Battle Born drop-in LiFePO4 batteries.
Required Components:
- WS500 Alternator Regulator- Updated to the current firmware revision and configured with the Battleborn Batteries charging profile.
- WS500 Wiring Harness, such as the WS500/PH or WS500/NH.
- WS500/BT Battery Temperature Sensor
- 500A/50mV Current Shunt
In LiFePO4 systems where CANbus communication is not available, the best practice for alternator/regulator control is to provide the regulator with the ability to monitor ambient battery temperature and current into and out of the batteries. By closely monitoring battery temperature and the charge rate into the batteries, the WS500 can charge more safely by staying within the Battleborn battery's recommended C-rate and working temperature range.
When installing the configuration profile for your batteries, be sure to set the proper battery capacity multiplier to ensure that the regulator will be able to accurately monitor charging based on the overall capacity of the batteries being charged. See the Configuration Utility User's Guide for instructions when modifying the configurations profile.
In order to safely monitor charging voltage, the regulator's power and voltage sense wires (red and red/yellow tracer) must be connected in a location that's always on alternator side of any switches or fuses.
