Lithium Trolling Motor Battery Review
Posted on 3/28/19 at 10:32 am
Posted on 3/28/19 at 10:32 am
About 6 months ago I purchased (2) 60A lithium batteries to put in my flats boat for weight reduction. The going price for one of these batteries in the states is close to $1000 a piece, so being the bargain shopper i am, I found a pair on Alibaba.com for $700 shipped to my house, with a charger. After extensive research i bought them. A 36 days later via a ship from china, they arrived at my house. These batteries weight 19 lbs a piece compared to lead acid which is 60+ for a comparable battery.
they also have a smaller footprint as well.
Per the specs, these batteries are good for 80% charge capacity @ 2000 cycles.
As far as performance, its only been 6 months, but I couldn't be happier. they have performed flawlessly on 20+ trips. I have gone on 2 day sight fishing trips without charging in-between and they have still yet to die on me.
As far as charging goes, each battery takes no longer than 2 hrs to charge. THe good thing about lithium is its ability to handle 20+amps charging with no downside.
PS, they also have not blown up or caught fire!** these batteries adhere to all of the safety ratings as any other battery.
I wanted to write a review because there isn't much info out there on this new technology. Hopefully this helps anyone debating if they want to make the switch or not.

the other battery in the picture is a Group 24 for reference.

Looked into them a few months ago and decided my wallet was still happy with lead acid. They’re definitely the future though, hopefully the price comes down as manufacturing gets more widespread. Really seem perfect for marine applications with outboard alternators having amps to spare while running.

Nice; any reason you went with two 12v's instead of one 24v? I looked at swapping the Odyssey's in my Fury about a year ago, but decided against it because of cost. If I did, I would probably just get a single 24v though.

So about $5.83 per amp hour vs $1.11 (Standard Deep Cycle grp 27)
But yours includes a charger.
That 20+ amp charge is nice, especially for back to back daily trips
Weight
3.16 amp hours per pound vs 1.70 ah pr lb (grp 27)
looks good here.
For the price Id like to see you go at least 5 years, wouldnt you think? I have been intrigued by these for a while now

A few reasons. One was cost again. It seems as though the 24v batteries were more expensive. The biggest reason was charging. I wasn't really sure what type of charger to get for a 24V system.
the 2 12v's do give me more room in my front compartment as they are tuck up against the side of the compartment instead of one larger one protruding out.

Via the specs, it should be a 38 year battery if I fished 52 weeks a year and it has a 2000 cycle life. Do i believe this , no, but i do believe it will go double a lead acid.
The price is up there, its fishing and everything is expensive now, so why not throw batteries in there. to me, weight is a major factor, so the price is worth it.
its just like someone getting a 250 on there bass boat, because the speed is worth the price.

For sure. For about 5 xs the price, Id be fine with double a lead acid, given the other factors. We use a lot of amp hours hanging out on our boat(3 grp 27s) I going to wait until prices drop and Amp hours go up. this is promising though

They have but not all lithium batteries are the same and technology has come a long way.
The type that I have is the Lifepo4 , which is a very stable form of these batteries. The batteries all have internal batteries management systems on them as well.

Agree and it still has a ways to go.

Cool....I like that yours came with a charger.

LiFePO4 are way more stable chemistry wise than the lithium batteries most people think of. They just sacrifice capacity for that.
LTO is the best option for lithium but they are super expensive. They're more stable than a lead acid car battery and you can literally beat it with a hammer and stab it with a knife and it wont combust. You can also overcharge the hell out of them or run them completely dead to 0V with no negative effects

No its not. Its the small rectangle in the OP picture. Im sure you could mount it in the boat if you want as it is quite small. Just not waterproof. What I may do is have the leads come off the batteries out to a "onboard charger plugin". So i will not have to open a hatch to charge them. (no gas expelled with these batteries)
But honestly, at least how my boat is set up, its not an inconvenience to open the front hatch and plug them on.

Gotcha. Good points. I remember the 24vs being very expensive too. I need to find out which brand Hells Bay is putting in their newer skiffs. I fish on one often with a 24v single and it's incredibly small. I'm sure it probably cost $1000+ though ha.

I bet its the Relion brand. they are $$$
Relion RB24V50 Lithium Ion LiFePO4 Battery 24V 50Ah
$1,268.51

SCB put them in their Stingray and i think they were $3k if i remember right.
Posted on 3/28/19 at 3:11 pm to Elusiveporpi
Just googled and you're correct. That's them.
at $1250/battery. Above my pay grade ha.

How did these work?
Posted on 2/17/20 at 7:25 am to NYCAuburn
In my third year this spring with 2 12V lithium batteries. I could not be happier. I'm hard on batteries. I fish from Friday afternoon Thru Sunday and stay on the electronics. Drain the piss out of em. Leave stuff on for days. I come home from the weekend and forget to charge them sometimes until Tuesday or Wednesday. They bounce back 100 every dang time. I have zero complaints. I have noticed ZERO drop off. I take them to the hunting camp to run lights, radios, etc. Use them all weekend no problems. If they finish this summer in this shape it will officially be the best battery I have ever bought. I never have batteries hold up this strong for three years with the abuse we put them thru.

So how does Alibaba work? You contact the supplier? Doesn't look like you can just purchase the product right then and there.
