Hey Landon. The Bright Way 12V Onboard Battery Charger for Hydraulic Dump Trailers item # BRW49FR doesn't work with Lithium batteries but I have a comparable option that does.
It's the NOCO GENPRO On-Board Battery Charger item # NOC44FR. This is also a 10 amp charger that works with 12V batteries up to 230 amp-hours. It'll connect directly to your trailer's battery and plugs into a standard 3-prong electrical outlet.
What size is your Lion Energy lithium battery?

The NOCO GENPRO 10 AMP,NOC44FR, does handle LI batteries but knowing the size and rating on amp hours, etc would be beneficial to further qualify this application. We did use some LI batteries on a unique trailer application that supported a major college sports team for handling their associated game and cheering section gear and needed an external and internal lighting sytem as well as a major league 'BOOM BOX' through an appropriately sized inverter and eventually even an 'onboard' 'capachino machine' for the staff, don't ask it was a last minute add. The battery array was supported by 3 (100) watt solar panels as well to help maintain a full state of charge for this unique application. We installed a separate charger for each battery to maintain separation of the system for maintenance and to ensure the highest quality input current to these significant batteries and associated system. We wanted to keep the possible 'heat load' as low as possible so decided on 3 separate chargers instead of one multiple bank system as we mounted this system in a 'beneath the trailer' enclosure. We use the NOCO battery charger family exclusively in our specialiazed applications with never a failure and the highest level of battery charging and maintenance possible at a reasonable price.
