Hello,
recently we converted a HiSun Sector E1 to Lithium Iron Phosphate batteries. The batteries now have 16.4 kWh (315 AH) of capacity, 24 horsepower peak, and it reduced the weight of the unit by 360 lbs. We were able to use the same onboard charger but did upload a lithium profile to it. We also needed to add custom battery trays. The conversion process is explained below in this video:
We also now have a 4 port supplement charger option for those wanting a dedicated charger or are using 1 of the batterie to run a winch/snow plow with more power requirements:
Finally we wanted to show cold weather use and how the unit can be setup to perform regen in the cold without problems as the batteries can regen and stay warm:
