I would think the 24 volt batteries have to be run by joining the power of the 2 batteries and this could not be altered by connecting to this system. I would consider getting the strongest battery I could find and use it for cranking and accessories. Also, fish finders can be effected by trolling motor static if hooked to the same battery. You could google Blue Sea to get their phone number and ask them. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality… You get what you pay for. *by M***N on 17 October 2025* These are amongst the highest quality switch’s that are available for use on Boats, RV’s, Campers and Solar Installations. Highly recommended, and well worth the extra expense for a long life, no issue service. Quality always pays off in the long run! Happy Sailing! :) ### ⭐⭐⭐⭐⭐ Same mounting as our old one. *by P***A on 16 August 2024* Used this and a pile of 4G cables to create a house bank and engine bank on my boat. Works good. ### ⭐⭐⭐⭐⭐ A much simpler combiner switch... *by S***H on 9 February 2017* This was a direct replacement for my previous - and working properly - Blue Sea 1-2-Both-Off switch common to many boats. It's much simplified, and was recommended - even though my existing switch was fine - by the marine electrician who surveyed our boat's setup during our replacement of our massive battery bank. It fit exactly where my previous switch had been. There are two studs for each battery; ordinarily you'd just leave it in the '1' position; the other shows as 'emergency start' on their instruction page, but it merely puts both batteries on the same circuit. The charging circuit from your alternator is always live to the second battery; turning the switch to the yellow-labeled position bridges the charging and discharge lines for the two batteries. Likewise, of course, the '1' position also has continuity all the time between whatever charging sources you may have, and whatever destination your power will arrive in; they show a panel icon to indicate that arrival point. Very simple, and the usual robust quality you expect from Blue Sea products. ## Frequently Bought Together - Blue Sea Systems 5511e e-Series Battery Switch Dual Circuit Plus, Red - Blue Sea Systems 5026 ST Blade Fuse Block 12 Circuit with Ground and Cover - Marine Wire 2 Gauge Marine Grade Wire Include 2AWG 25FT Red & 25FT Black,2 AWG Tinned Copper Oxygen-Free Boat Electrical Cable for Automotive/RV/Camper/Trailer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/68603785-battery-switch-on-off-afd](https://www.desertcart.vu/products/68603785-battery-switch-on-off-afd) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-22*
