John E Davies Posted March 12, 2021 Share Posted March 12, 2021 (edited) Lithium batteries are happiest when they are not subject to extreme temperatures. The Oliver battery box has vent holes in the door, but the actual "container" itself is sealed tight, and the area above and around it is a dead end air space; there is no way to get the heat out in summer, or to get warm cabin air in during winter. I wanted to get good airflow through this space, with natural (convective heat flow) and forced (computer fan) movement. Another benefit is that the air flows from the open cabin space and through the two electronics compartments, cooling the hot accessories that are installed there. Like the battery box, those spaces have no natural airflow - they get hot in summer and cold in winter. This will help to moderate those temperature swings. Here is how I did it on Hull 218. FYI, to the best of my knowledge the factory lithium package does not include any kind of venting to the cabin interior, though an electric heating pad is included. Please comment if this is incorrect!
