I put these on my camper as an upgrade and they have worked great ever since. Only downfall is the plastic does fade in the Sun but grab a can of paint.

I am very impressed with how strong and stout the materials are and the thickness of the base plate. Highly recommends for setting up a multi piece lithium battery with inverter charger & solar type project. Thanks !

Purchased this item for my boat, and I am highly satisfied with quality of the enclosure. I like that each of the four lugs in the version that I purchased are all separate. Meaning, each stud is a separate bus bar, so there are four separate connections in the same enclosure.

Fairly fast shipping (from China!) with decent tracking. I was amazed by the quality of this product. Not the cheap junk I expected. The plastic was thick, reinforced, and strong, the bus bar was very thick and the studs seem like quality stainless with lock washer. The cut-outs for the cables are well defined yet strong and ideally cut out using a rotary tool like a Dremel. The mounting studs for the bus bar are counter-sunk into the plastic housing and covered with a foam pad. Even if the bar heats up and melts the foam it shouldn't make contact with any metal the plastic housing is mounted to; a nice bit of safe engineering. Highly recommended.

I own a jeep TJ, so I have upgraded it over the years and my battery was at its limit for attachments. I installed these (power and ground) and feel much better about the connections. It looks good, makes me feel safer, and works as expected. These are well built, although not waterproof, can easily have openings sealed to make it so.

I liked the terminal cover, couldn't find another style in this amp rating with as nice of a cover. The cons are the bus bar is made of brass, instead of copper, and I would not mount this to metal, as the base plate is thin, and there are screw coming from the backside to mount the bus bar to the base plate. Very little distance from the mounting screws to the mounting surface. I'll be mounting it on a non conductive surface
