  • Bullet Proof
Size: 1 Pack Style: 50Ah Trolling Motor Battery
It’s a well-known fact among Waterfowl Hunters, if you what to test the durability of something, take it duck hunting once. If you want to destroy it permanently take it twice. Your product survived two seasons and surpassed my expectations to say the least. In November of 2022, I purchased a Power Queen 50ah battery from Amazon. I bought it because it had generally positive reviews and it was within my modest budget at the time. When it arrived, I had no idea of the value of what I had just purchased. I specifically purchased the battery to power a trolling motor on a light kayak used for duck hunting. Please allow me to give you a brief rundown of what this battery has been subjected to: 1. This battery has been completely submerged in water for hours on end. 2. It has been well used for two entire ice-cold duck seasons in the backwaters of Michigan. 3. It has survived hundreds of miles of being bounced around in the back of a truck bed as we drove down poorly maintained dirt roads. 4. It powered a 50# thrust trolling motor as we explored miles of weed and grass choked pond and rivers. 5. It has recovered a boat that was sunken and completely submerged in 5ft of water. (Fun Fact: An electric winch will work under water when connected to your battery.) To top all of this off, on the last day of the season of 2023-2024, I was driving on my way home when a fellow driver caught my attention to let me know something was wrong with the boat I was pulling on a trailer. After I pulled over, I couldn’t immediately find anything wrong with the boat or trailer. Then I stepped around the passenger side and there it was. My 50ah battery had fallen out of the boat and was being dragged down the road by the cable connections. It looked bad to say the least. The electrical connections were destroyed and the few strands of wiring from the positive terminal were the only thing holding on to the battery. To say I was upset would be an understatement of a lifetime. There was nothing I could do except to collect my battery and finish my trip home. After I got home, I put everything away and made a plan to take the battery to the recycler. Last night, in my shop, I walked past the battery and gave it a good look. It was battered and covered in road rash but on closer observation it looked mostly intact. I decided to try to plug it in to the charger and see what happened. To my absolute surprise, it was still working! A quick check with multimeter confirmed it! It was still working just as well as it did the day I bought it. The case has been compromised and this particular battery will probably not be used on the water again but it will be replace with a Power Queen for sure. I’m impressed with the durability and construction of this battery. It has taken more abuse than it was made for and it just keeps working. ... show more

  • So far, very pleased
Size: 1 Pack Style: 50Ah Trolling Motor Battery
I ordered this to use with my astrophotography rig. So far the only thing I have ran with it is the mount as I have a 120v supply for the rest of the equipment and my recent capturing has been around power. The battery, when placed on to use with the EQ35-Pro mount sits around 13.7v when turned on. After over 8 hours of use on the mount, it has only dropped to 13.2v. The battery arrived very quickly and was WELL packaged, unlike another battery I had purchased and had to get a refund for as it was damaged by a small "crunch" apparently on a corner since it was not packed well. So far, I've been very pleased with it. It's MUCH lighter than the 36Ah AGM battery I was using. The real test will be when I have to use it to power the entire rig (EQ-35 Pro, ASI533mm Pro camera with filter wheel, ASI290mm guide camera, RPi running Stellarmate and an ASI EAF. The nice thing, I do have a generator that I take out in the field with me (Westinghouse iGen2500) when it's cooler out and I can set up my tent with a heater in it to monitor the captures. It remains to be seen how long this lasts, but so far, I do have to admit I have been impressed for the price. ... show more

  • Excellent battery for native Titan X 12.5.
Size: 1 Pack Style: 50Ah Trolling Motor Battery
This is the perfect size battery and a ton of power for small-medium applications. Don’t expect to run livescope + other accessories for a full 8 hours. You may just squeak by with 50ah, but it’ll be extremely close to dying after 8 hours. This powers a fish finder and GoPro recording all day 8-12 hours with plenty left over. ... show more

  • For my trolling motor on the beach
Size: 1 Pack Style: 50Ah Trolling Motor Battery
I decided on this one for my inflatable raft + trolling motor setup. The customer reviews were positive and I have been satisfied with the battery and the customer service messages since my purchase. My raft is down a long steep bank so I carry the battery up to the garage to store/charge with a 25l sized backpack. With the low weight, it’s been no problem. I have taken the raft and motor into the sea for 45min-1hr rides and we have not tested how long it lasts by allowing it to lose power, but it feels about what’s expected for how much was left based on the trip when I can see capacity state on the battery charger. I have tried a few battery meters and the first was not working (always at 100%… ), the second one is tracking capacity but I don’t trust it quite yet because it drops rapidly from 100% to 78% in the first 5 minutes and then stays at 60-70% for the majority of the trip. That part is not the battery’s issue but I haven’t found a great way to feel confident of what’s left in power. It’s a great battery for my use, nice customer service so far. Lightweight, was competitive in price. You will need a charger that is liFePo4 (lithium iron) compatible. I had one. You might need different terminal connectors, the supplied ones are minimal and difficult to attach alligator clips to. You will need some patience in shipping, it takes a few days. ... show more

  • best and lightest battery
Size: 1 Pack Style: 50Ah Trolling Motor Battery
I've never left a review in my life, but this battery is great. I bought the 50 ah for my Jon boat in wired it in. My switch Panel has a USB C output so I can charge phones, cameras, flashlights, etc... I've done many overnight camp trips with the battery using my lightbar, interior lights, and even ran a shrimping light for 5 hours. With all the use I've never had it drop under 13.3v. ... show more

  • Great price

Battery arrived quickly. I installed it on my enclosed trailer with 200W solar panels. Charged up immediately. I use it for keeping a small refrigerator running when not on shore power. Seems to be working great. Couldn’t be happier with performance and price. Update Jan 2024. This battery has been great!!! I have a 400watt solar panel setup on my enclosed trailer. I run a Whinter refrigerator/ freezer off this 50ah battery and it has out performed my expectations. Great battery!!! ... show more
