Choose a Circuit Breaker - Our 2HP/3HP motors are designed to draw 50A/40A during their full speed driving in the water. but the motor could draw more power if working at harder water condition. If you want to select a circuit breaker for more protection and as your main power switch, it should be at least existing 15% of max Amp capacity. Also, depending the quality of the circuit breaker, the breaker's performance will drop during its life time. So, you may want to pick a breaker at 25% over the max. We suggest Min 65A circuit breaker for the 2HP and Min 50A for the 3HP model if you need one. Since the AC motor has electric Power Control Board (PCB) built-in, in the most case, the motor could cut off the power by itself if problem detected.
High Frequency Consumer Issue - Most problem is from the Battery when your motor not working. If your motor stop at the middle of water with beep sound warning. First thing to check is the battery level indicator light. Your battery voltage is low if Red light only or even no light to display. The PCB of motor will cut off the power when battery voltage out of working range. After the power cut off, the battery won’t be drawn by high output, so its voltage will be recovered by itself. The motor can run again but it won’t last long, maybe last couple 10 seconds only. This problem may be happened when using any kind of batteries. You may just use your battery for other device, or your battery may be only few months old. I saw a lot of those cases, since you won’t be able to see the battery condition from your eyes. So below battery section is very important to know.
Battery Charger & Maintenance - Fully charge the battery does not mean the battery capacity good. It will depend on the condition of the battery. To select a good battery and maintenance the battery in good condition, below instruction you may need to follow.
1) Purchase the right marine deep cycle battery or new Lithium battery. Check the battery voltage by a voltage meter when make the purchase.
2) The AGM deep cycle battery will be a good option for the price and life time. A better battery should be always heavier if the same type.
3) Please find a local professional battery store to purchase your battery. Best not to purchase your battery from Auto shop. Do not use starter battery as your trolling motor battery.
4) Always fully charge the battery before storage or after your boating trip. An overdrawn battery kept for 30 days may cause serious internal damage and effect its life time. Many battery damages could not be able to recovered.
5). You may want to use good battery charger for your battery. We suggest to use NOCO genius charger with maintain feature. It could help your battery to restore the performance by following their instruction.
