Power Queen 12V45Ah LiFePO4 Battery Group U1 Lithium Marine Battery, Built-in 45A BMS Low-Temp Protection Deep Cycle Battery, 15000+ Cycles for Power Wheelchair, Mobility Scooter, Trolling Motor 40lb

Ordered to place in a 2006 Yamaha Rhino side by side ATV. I wanted a LiFePo4 battery as the Rhino is heavily used during the winter and I have had good luck in the past with LiFePo4 batteries in cold weather. This battery did not disappoint. Had several days of use in single digit Fahrenheit temperatures. The Rhino is kept in an unheated garage and several nights went below zero Fahrenheit. Started like a champ every morning.

I bought these for my Merit wheelchair. This is the second set I have purchased. They are great. So light and powerful. Just be sure to follow their instructions and get the proper charger.

I got this guy for my Newport 36lbs trolling motorIt’s light compact and plenty of power for my trolling motorVery happy with my purchase

I am a big fan of transitioning from classic lead-acid, AGM batteries to LifePO4 technology for everything that moves, motorcycles, boat, sailboats, etc... in the outdoors. The Power Queen 12.8V 50ah is an excellent deal and quality product. If you poke around Amazon, you'll find other brands of the exact same battery but in other color shells with different branded stickers. Some sold at around the same $200 price, others quite higher. I suppose they are all the exact same batteries. In any case, $200 for 12.8V 50ah is about as inexpensive as it gets today. I received the battery on time and aside from Amazon's product shipment notice, Power Queen also sent me detailed delivery updates which I thought shows consideration. The battery was well packed in protective material and along with it came a 5-yr warranty card, a small bag of spare terminals (nice touch) and a manual written in perfect english with in-depth electrical data and specifications which is very unusual. I bench tested the battery using a Renogy battery monitor and all numbers published in the manual were spot on. There is a full discharge capacity vs voltage diagram in the manual which is very handy for owners to get a grasp of how the battery delivers power over time. I did a full discharge test until the BMS shut down the battery to see if a small 20W solar panel connected to the battery would wake it up and allow charging it again. That worked perfectly. I also tested charging with NOCO's Genius 10 10AMP, lithium compatible charging which I highly recommend. It's a fanless design very well made charger.
