Trolling motors are popular among professional and hobby fishermen, allowing you to reach fish stocks at middling depths away from the shore. Trolling baits and lures at up to 9 knots, (or 15 between fishing areas), is a great way to hook salmon, mackerel and kingfish! But the continuous motion of trolling uses up a lot of power, especially for fishing enthusiasts spending all day on the water, or those in trolling competitions. That’s why it’s so important to choose the right trolling motor battery!
So why should fishermen choose lithium batteries for their trolling motors?
Battery Life of Champions
On a long summer’s day on the water, the last thing you want is a dead battery when you still have a small catch! This is relatively common with lead-acid batteries; a lithium battery lets you stay out longer and get further out, where the fish stocks are larger!
Lithium batteries like our LightningVolt™ are deep-discharge models. This means you can use up to 95% of the battery power many times without damaging the battery. (Discharging a lead-acid battery below 50% will damage it). Marine lithium batteries also have a consistent voltage output until they’re completely discharged. With lithium, every pound of battery is useful, and you aren’t carrying around any dead weight! You can also charge LightningVolt™ many more times than traditional batteries, without experiencing reduced runtimes. This means that in the time you’d have to replace 10 AGM batteries, you only need one LightningVolt™.
A Lightweight Trolling Motor Battery
Trolling boats come in many shapes and sizes. In a big boat, weight doesn’t matter as much. In a smaller boat like a tiny bass boat, bay boat, canoe, kayak or skiff, weight makes a big difference, and you don’t want a trolling motor battery adding any more than necessary. While average gel cell and AGM batteries weigh 60lb-70lbs, lithium LightningVolt™ batteries only weigh 24.9lbs. With up to three batteries in a boat, that’s a significant weight saving. This reduces pressure on the engine and frees up more of the weight allowance for a bigger catch!
No Mess, No Hassle with Lithium
Lead-acid marine batteries can take 8–10 hours to fully charge, meaning you have to pre-plan and charge them up overnight. As well as lasting twice as long between charges, lithium batteries charge in 2–6 hours, so you’re ready to go in no time. With LightningVolt’s special quick-charge feature, you can throw the timetable out the window and go trolling on the fly. Lithium batteries also have almost no self-discharge, meaning you won’t lose power between outings if you only get out on the water on weekends.
Lead-acid (flooded wet-cell) batteries aren’t designed to handle the vibration of a trolling boat. They need to be mounted in an upright position to avoid the risk of damaging acid spills. But with lithium batteries, there’s no worrying about mess or spills when you’re out on the water. We originally designed LightningVolt™ batteries for heavy-duty truck applications. We build them to handle high levels of shocks and vibrations. They can be mounted in any convenient position with no risk of leaks, and the connections are welded on to prevent the boat’s vibrations from shaking the cables loose.
A Multi-Purpose Battery
Waterproof, GRP size 31 lithium batteries make good marine batteries and power a range of equipment, not just trolling motors. Lithium batteries are also suitable for sonar, fish finders, shallow water anchors and chart plotters. Head to our marine battery page to find out more!
Why Choose LightningVolt™?
Our 100Ah batteries are resilient, reliable and tough enough to handle long days on the water! They work in extreme temperatures and perform to a higher standard than traditional batteries even below freezing. We also test them in saltwater conditions, to ensure that they do you proud out at sea! On top of this, LightningVolt batteries are designed to be charged thousands of times without being damaged; they can handle roughly 2,000 charge cycles at 95% depth of discharge and over 4,000 cycles at 50%. This is a significantly higher number than AGM or lead-acid batteries offer.
