## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality durable plastic. Excellent weather resistance.
*by P***T on June 17, 2025*

Very high quality battery box. It is robust and durable. I have it mounted on a shelf on my trailer tow bar to supply power to the electric brakes and electric winch. It was easy to fit and is made of thick tough plastic. For me I put duct tape over the vent holes as there is ample ventilation via the cable holes and it kept out the rain (see photo). I would recommend and would buy again if I needed another one.

### ⭐⭐⭐⭐⭐ Very good
*by L***O on August 23, 2025*

Very good battery box

### ⭐⭐⭐⭐⭐ Great Durable Battery Box
*by E***Y on August 5, 2025*

Great, durable US-made box. I've used these for many, many sump pump installations, trailer and camper battery installations and on numerous hot rods and dune buggies over the years. I've had batteries literally split, blow up or leak and it's nice to have a bulletproof battery box to contain the mess. Highly recommended to protect your boat, race car, hot rod or basement floor!
