That's Amped Outdoors owner Matt Lardinois (middle), talkin' the advantages of lithium batteries over traditional lead-acid and AGM batteries. We got on the phone with him to see what the hype is with the lithium game – here we go:
How does better battery performance translate into more fish caught?
> "...quite a few different ways...lithium [Li] batteries are better than both in lead-acid and AGM.
> "First thing – trolling motors. When you have a traditional lead-acid or AGM battery, the battery starts at about 12.8v per battery. If you have batteries in series it's obviously a higher voltage, but then the voltage will gradually decrease as you're using it.
> "Lithium iron phosphate [LiFePo] batteries...could be between 12.8 and 13.2 discharge volts, but it stays at that voltage throughout the day while you're [using] it.
> "[So with Li] you don't have that [voltage] drop. You're not noticing that your trolling motor is slowing down.
> "Also, a lead-acid battery is 50% efficient, an AGM battery can be up to 80% efficient, where a Li battery traditionally is going to be 100% efficient, if not better.
> "If you have a 100ah lead acid battery and a 100ah Li battery, the Li battery is going to give you double the operating time of the lead acid. Not only get better performance, but you'll also get longer operating times out of them."
[All you long-pole guys that are tired of your trolling motor going at 4 speed when it's on on 10 at the end of the day, take note!]
> "As far as Li performance with electronics, it's going to be very similar.
> "Modern-day electronics draw a lot more power. By running a Li, you get a higher efficiency rating – longer run times out of them – double that of lead acid or AGM.
> "The other advantage is that, just like with trolling motors, a Li battery is going to stay between 12.8 and 13.2 [and] higher voltage gives better image quality pretty much the whole time you're using it.
> "People have [also] noticed that instead of running all your electronics on your starting lead acid and AGM battery, running a dedicated Li battery to their electronics eliminates electrical interference within your entire [electronics] system."
What's a big misunderstanding people have about how batteries affect their electronics?
> "Your fishing electronics, in general, work best above 12v.
> "A lead acid and AGM battery, especially with modern-day electronics, the power draws can drop below 12v pretty quickly – that's where you start to lose performance.
> "...higher voltage gives better image quality. A 12.8v LiFePo battery will discharge between 12.8 and 13 – that's perfect.
> "All these screens are made to work up to 17,18, 20 volts, depending on the brand. ...what [anglers] don't understand – the reason why they're getting better image quality is that they're going from lead acid battery to Li [constant power].
> "You're not going to get a better image quality going to a 16v battery versus a 12.8v battery. [As long as it stays above 12], it won't matter what the voltage of the battery actually is."
Any common issues with boats and electronics that Li batteries essentially eliminate?
> "The biggest issue outside of what we discussed already...is just overall capacity.
> "Today, we're not in the days of running small 5-9 inch screens anymore. People are running 9-16 inch screens – the most popular are 10-12 inch screens. Those draw sometimes 2-4 times the amount of power of the smaller screens of the past.
> "With having that higher draw, having the more-efficient, higher-capacity Li batteries are going to allow them to run a full day or even multiple days and not have that battery die prematurely."
At what point should people seriously consider switching to Li batteries?
> "There's really not a scenario where traditional batteries are going to be better than Li within the fishing industry.
> "If it's electronics, there's a 100% advantage of going to the Li. They're lighter, they last longer.
> "People think they cost more upfront. That's very true, but in the long run it ends up paying off.
> "A lead-acid battery's typical life-expectancy is 2-3 years. A Li, if you properly take care of it, will last 10 or so."
