Installed and setup as a 24v system for my trolling motor. So far so good. Stored indoor during the winter to protect it from our extreme cold weather. The group size is a little too big for my original plastic bay, so had to buy new ones. No biggie.

I used an older switchable ocharger made for lead acid and lithium batteries. When I selected lithium and charged it all day, the battery web app only showed 66% full. I solved this by getting a smart charger. It’s charging well now.

I have not had a chance to run my motorhome off dish yet since I’m always connected to shore power, but I am able to see in real time if there’s anything wrong with the battery

The FIUNIE battery arrived in excellent packaging. First order of business is to load the Bluetooth app. The app is not available on the Google Play Store, you have to download the app directly from Beijing. No way I'm doing that; who knows what nefarious things that app would do on my cell phone. Downloaded the BAT-BMS app from the Play Store and it works fine with the FIUNIE battery. Wasted a lot of time searching for alternative BMS app to use with this battery (reason for the 4-star rating). Battery was at 49% charge state at delivery, so connected it to ARDROIT LifePO4 50A charger (AD-1250). It took about an hour to bring it up to 100%. I recommend the charger; 5-star. Have not yet used the battery; plan to use it for portable Ham radio HF station during Parks on the Air (POTA) activity.

I have 2 of these as my trolling motor batteries and they are super light (around 20# I believe) compared to my group 27 VMax batteries that were 80# each! The app works great, after all day of spot lock anchoring and trolling. I still come back with around 50-60% left and that's literally 6 hours of use.

I love this battery. I use it on a 8 foot pond boat for the trolling motor. The charge lasts several hours past a days use. It's made to last for sure.

Buyer be very aware!!! This battery has ZERO warranty. They claim 5 years but that's just because you can't get in contact with anybody. Amazon should be ashamed of letting things like this happen. The battery was great at first! The BMS was really good and easy to use but less than 6 months in it's stone dead without any recovery and it sat in storage at approx 68% battery charge(the sweet zone for lithium batteries). I've tried everything from trickle charging, to passing through a lead acid. It's just dead. There is no contact availability for the seller and Amazon will not help at all. If you question what I'm saying, just try and find contact info for the company before you buy. The proof is black and white. I wish I'd done a little more research before throwing $170 in the trash. They already got me, so I was just hoping to help save a few other victims!! Spend a little extra money and get a reputable brand, it'll save you at least $170 bucks!

Incredible!! My audio system demands 2700watts max and 1900 watts ish continuous power. This is a secondary battery for my audio Running stock 130amp alternator on a new nissan Altima. With everything running on car and sitting in park audio full tilt the battery never drops below 99 amp hours/98% charge. Driving it never drops below 101amp hours battery caps out at 103 amp hours. Car never drops below 14.1 volts driving and never lower than 13.9volts parked Threw it in car one month ago new at 60% charge. Drove around music full tilt for a hour and it kept continuously building charge to 100% while taking a heavy drain. Before this battery car was dropping down to 12.4 volts while driving ! Even at 4 degrees outside the charge was still 100% sitting in cold car trunk outside with freezing rain all while still showing 32 degrees for battery temp on the app. I bump driving 3 hours a day and 1 hour roughly parked. Never seen this battery drop below 98% charge since February 1st 2025 it's now March 9th. I'm gonna gift this battery to some friends and family. The app is really cool can control if it charges and discharges and live monitor every thing on battery via Bluetooth app. is Bulky but at 103amp hour capacity still lighter than the car audio 30amp hour agm battery I was using before
