Blue Sea Systems e-Series Battery Switch

While battery switches may not be at the top of your grocery list, you may want to look here when the time comes. Manufactured by Blue Sea Systems, the aforementioned battery switch comes in a variety of styles, and is quite inexpensive in price for what it’s worth. Features of the above-mentioned battery switch include the forthcoming:

The Breakdown of the Features

It’s easy to get caught up in a product that promises a ton of great features like the above mentioned from Blue Sea Systems. Boasting a maximum voltage of 32V DC, with a continuous rating of 350A per circuit, the aforementioned meets ABYC requirements, as well. With an ISO of 8846, and IP66 waterproof, you can enjoy the benefits of simultaneous switches for two battery banks that are isolated thanks to the dual circuit implementation. The terminal stud size has a measurement of 3/8-inches – 16 for those who are curious, and if you’re interested in if it will separate for on and off grid inverters, you should do some more research on switches, but know that this is rated ONLY for dc.

The First Impression of the Product

One of the very first things (after purchasing) that was noticed was that the installation was very easy and simple – no matter what your skillset is. Even if you don’t think you’re the handiest person, installing the aforementioned Blue Sea System battery switch is a breeze, and is great from smaller marine batteries to even moderate sized ones without being overkill or not enough. The overall design is very solid, and I don't feel as if there needs to be any replacing of this battery switch anytime soon. The professionalism of this mechanism is quite supreme for the uses, so for those that utilize their boats quite often, you’ll understand how important the appearance and sleekness of the appearance is! After researching and purchasing, it does exactly what’s intended of the product without any worry at all.

The Advantages of the Product

An advantage of this battery switch is that you don’t have to worry about the battery draining after not turning on the battery after longer periods of time. Even after not starting your battery for a month, you won’t have to worry about the battery not turning on because of the fantastic implementation of this battery switch. There are a ton of styles, including dual circuit, dual circuit plus, on-off, and on-off with AFD, as well as selector 3, 4, both with AFD or a selector 4 POS. Another advantage of this battery switch is that the operation is smooth, and for the price, it’s fantastic! 

The Disadvantages of the Product

The only disadvantage of the product is that it doesn’t come with the panels on the side of the battery switch that’s advertised in the photos. While not a huge disadvantage, some people need or want it for ease of use and implementation. Before you hook this up, you should research how many volts you have and how many you can hook it up to ensure that you don’t void the warranty. While not a disadvantage, those who aren’t very weary of the max volts can ruin their chance at a return if they aren’t into the product. Before you go off and put water on this battery switch, you should know that it’s not waterproof, but it is water resistant. There’s a slight difference, and you shouldn’t go out of your way to intentionally put water in or around the battery switch. It is related to the electrical field after all.

The Final Verdict

Overall, I think the design and installation of this battery switch is solid and simple while performing as intended. The price of this battery switch is fantastic, and you won't be spending an arm and a leg trying to purchase something you might not like/something that doesn't work for your lifestyle; however, if you're having any trickling problems with your battery, you'll want to use this with a flush mount that's nice!
