Great products. Customer service helped me out with a free replacement. Bought 2 12v batteries for my trolling motor. 1 the bms kept shutting off the battery. I'd have to jump start it to get power back. Sometimes once a trip, Sometimes 4 or 5. I contacted CS and they directed me to a couple test to do. After a few back and forth they sent me a brand new replacement. Ive had these batteries since March 2023. Bought an electric jack for my camper hitch. Works great! Definitely will get a battery for my camper next. Good company that backs it's products. I don't know why other had problems with CS.

I haven't had this long (~5 charges) but compared to lead-acid, what a difference! This is now my 50 lb thrust trolling motor battery and I couldn't be happier. Higher end batteries of this type can be several hundreds of dollars. This one was in the $250 range. It has a 10 year warranty, which is double most, but even if it lasts 5 years, that would bring it into the same price range of a couple of lead-acid batteries. A single charge lasts significantly longer than a lead-acid battery so I no longer worry about running my motor on '5', for fear of losing power before I'm done fishing. The weight is also about half, which is important in my 12' fiberglass boat. And charging, which often wasn't complete by the next morning, with a lead-acid while on fishing trips, is complete in the middle of the night with this LiFePO4. Note that this battery type requires special charging, but most chargers, even low end ones, now have this option. While this review mainly focuses on the advantages of LiFePO4 batteries, and not this brand, I haven't had it long enough to single out brand differences. I will say though that the price of this one stands out as do warranty and how solid it appears. I'll update this review if I learn more over time.UPDATE Jan. 2, 2025:I used this battery fishing lakes all summer and on several trips in the fall. It is still performing as well as it did when I got it and I have nothing but great things to say about it. For a trolling motor, pass on buying lead-acid and go LiFePO4. If the price remains good, this brand has my strong endorcement!

So far so good, I was using AGM batteries 130 AH and was going through the full charge in about 3 and half hours on my trolling motor 80 lbs thrust. I use anchor lock a lot, which uses GPS to hold the boat in one position no matter the direction of wind or the current is moving. The motor will hold position by speeding up and down and turn the boat accordingly.I got a great tip from a professional charter fisherman to switch over to lithium battery so I did my research and found that this battery was the best bang for the buck and had a great ratings. I don’t know why I waited so long, I can run 4 to 5 hours (same use) for 3 to 4 days before I have to charge the battery. You get Bluetooth reporting directly to your phone on the app provided by the manufacturer, I get all the rundown on the condition of my battery.

I purchased this battery in November 2023 for my dump trailer. It has worked well and lasts much longer than my previous lead-acid battery. I recently dumped seven full loads of dirt (around 10K lbs per load) and still had over 60% battery left.

Well....bought 2 of these. 1 died within a year, won't even take a charge. The other us fine. Reached out to vendor to fill warranty through the Amazon portal and they string you along. It's been over 2 weeks going back and forth and I have to submit video evidence in addition to the standard proof of purchase and detail of issue. Under the guise of customer support...they keep telling me to cycle my charger into repair mode to let it attempt to repair battery. That's fine the first time, but we are now on the third request from them for video or picture evidence? I can't attach any files through the message app as it just keeps saying the files exceed 10MB. The last attempt the files aren't even 250k each?....no email contact provided? So....I guess I'll just attach this to my review warning all of you guys to buyer beware. A bit if an expensive lesson to learn....be careful what sellers you trust.
