POWER QUEEN - 190ah LiFePO4 Battery Terminal Covers

I needed a way to keep the battery terminals covered safely. I have several of these setup with repeaters up on mountain tops where it is a shared location. I didn't want some stray cable hitting to top of a terminal and cooking something. The BMS is capable of 150 amps continuous. That can cause some big sparks.

I tried measuring the neg battery terminal and drawing the part (didn't work). I ended up 3D scanning the neg side battery terminal and then creating surfaces from that scan. Then in Plasticity software I ended up doing a Boolean cut what I needed. Turned out very nicely.

There are several draft angles on this due to the original battery top being injected molded. The 3D scan showed this immediately once I started building the surfaces. First time 3D scanning an object and reverse engineering it. Took a little time, but wow. I am hooked.

I have a created a solid cover with no wire pass-thru. I will create other covers too with cutouts or breakouts.

Power Queen Batteries. 190ah is no longer available, but love the recessed terminals.
