I’ve been using this new technology for about a year now and it’s blown me away and nobody is talking about it. I’ve seen first-hand results where it tripled my trolling motor battery life and it saved me from being shut down and not able to fish during the pandemic when nobody could find batteries. I used it on my previous boat with batteries that were over a year old and were so impressed by the performance I installed it on my new SeaArk Pro Guide Catfish Boat.
When you’re running trolling motor batteries in series (24 or 36V systems) you’ll never get equal performance from all three battery packs. One of the packs will always be weaker in performance or will discharge faster. Your trolling motor performance is only as good as the weakest pack so if one battery is at 40% and the other two are at 80% you’re only going to get 40% performance. That’s where the Dual Pro BOS or Battery Optimization System comes in. The Battery Optimization System shuttles power from batteries and equalizes the system so you’ve always an equal system and get the full performance from your batteries. That means better performance, longer run times, and longer battery life. The BOS not only optimizes the batteries while you’re on the water it also optimizes while your battery system is charging.
The DualPro BOS can accurately predict and select the battery that needs additional energy to match the other batteries within the pack. This simultaneously and successfully extends the life of each battery in the pack, as well as increasing run times.
The Dual Pro BOS or Battery Optimization System is a small device that’s super easy to install. it’s self-powered so installation is as simple as mounting the DualPro BOS with four screws and then connecting four leads to the three batteries on your 36V trolling motor system. When you’ve installed the leads correctly a light flashes on the BOS (it even tells you when the leads are not connected right) and the DualPro BOS does all the work for you. You never have to worry about it again.
You also have the option of connecting your phone to the BOS via Bluetooth so you can view real-time info on the BOS system and what it’s doing and all the battery optimization history.
I’ve personally seen an increase in the run time of at least 300% the first time I tested the DualPro BOS on a 36V battery system with batteries about 12-18 months old running a Minn Kota Ulterra 112 trolling motor. That means more time fishing and less time at the dock!
It has long been an ‘accepted’ fact that a user would only get ‘X’ amount of years out of a battery. With B.O.S., these years are exponentially increased by keeping batteries actively balanced, which prevents over and undercharging. Furthermore, sulfating is held at a minimum as the weak link battery is no longer taken below the recommended level.
