Victron Energy Orion-Tr Smart charger

This is Victron Energy Orion-Tr Smart DC to DC Charger (Bluetooth) - 24/12-Volt 20 amp 240-Watt - Battery Charger for Dual Battery Systems - Isolated. Bought it by mistake for my RV and never installed. I realized it was the wrong item after the return period ended. This unit is intended for RVs or tow trucks with 24V electric system for smart charging of the 12V lithium batteries. Asking for half the retail price.
