Question: How long is the manufacturer warranty on this product?
Document: This is an excellent product. I used to have to switch my batteries on my boat, but now this switch does it for me.
Nice product. Easy to install. Works great. I used it for the first time 7/14/12. I played the radio in the boat all day and had no problem starting for the ride home. I took my time with wiring, and it took me an hour. I needed a few extra 4 guage batery cables, but not a big deal. It charges the batteries as described.
followed the clear instructions, 2 hours later (with one trip to store) all was in and working fine. A little tough reaching in around with stern drive, but switch was fine.
Worked as expected. Made switching my boat battery super easy. Would definitely recommend. Had a service provider install and he said it was easy to work with.
Used this to setup a dual battery system on my pontoon boat. I didn't want to get stuck on a beach, playing the radio, making margaritas, and killing the main battery. It has worked perfectly, and I like the ability to combine batteries if needed.
This is a good kit to add a battery to your boat or RV if you are looking for high quality and fully automatic functionality. The module automatically switches charging voltage to the battery that needs to be charged, and acts as an isolation module as well. Everything about this kit is waterproof and heavy duty.
The instructions were pretty easy to follow. I am mechanically minded and electrically challenged, so good instructions in this case was key. Got it all installed in my boat in a fairly reasonable amount of time. It's been 3 weeks and the boat has not blown up, all electrical stuff is still operable so I guess I did it right. Now I can float and blast the radio without fear of not being able to make a clean get away.
Nobody mentioned that this switch requires many additional parts and rewiring of the boat in my case to make it work. The instructions require fuses (around $35 each with fuse) and an bus bar + wire. If you don't know what you are doing it will require a pro to wire this together, not as easy as some say.
I was having troubles with my battery charging on my boat and read the reviews about this which were great. Well, I finally got it hooked up and took the boat out a couple different times, and never had a drain issue with the battery. The only bad thing about the kit was I bought the remote LED light for the dash and I think I broke it while trying to install so I cant see the lights.
I just installed this in my Boston Whaler 180 Dauntless and it's terrific. One switch to "ON" and forget about it. "On" just gets the juice flowing. Nothing more to do. Installation was pretty simple even for a novice. Blue Sea support was first rate for any questions. Go get it or upgrade! I hope this helps.
