  • Great battery, worth the buy.
Style: 12V 50AH
Awesome battery, took it out and trolled for about 5 hours and still had plenty of power. Light weight, easy to haul. I have a 12 foot aluminum boat and it moved very easy.

  • Compact and powerful
Style: 12V 50AH
Great battery it does have power. I used one to build my own battery bank with a 1000 watt inverter I can run anything I want when camping, it charges off solar or my alternator when driving so it's always full, and the other one is attached to my trolling motor and it works much better than my other marine batteries ... show more

  • Reliable and Long-lasting Power Source for My Boat
Style: 12V 100AH
I recently decided to upgrade my boat's power system, and after extensive research, I opted for a LifePO4 battery. After several months of use, I can confidently say that this battery has exceeded my expectations in terms of reliability, performance, and longevity. The LiFePO4 battery capacity is significantly larger than old lead-acid batteries. I can now roam my boat around the lagoon for hours and never worry about running out of power. This battery consistently delivers a stable and consistent energy supply, ensuring that all my onboard systems operate smoothly throughout my journeys. The peace of mind this reliability offers is truly invaluable. The standout features of the LifePO4 battery is its impressive lifespan. Unlike traditional lead-acid batteries, the LifePO4 chemistry is designed to endure countless charge and discharge cycles without significant capacity degradation. I have noticed minimal decline in performance, even after numerous trips and extensive use. This longevity not only saves me money in the long run but also reduces the hassle of frequent battery replacements. The biggest benefit is it no longer needs adding distilled water every few month -- a major hassle with lead-acid. Moreover, the LifePO4 battery's fast charging capabilities have been a game-changer for me. It efficiently absorbs power from my boat's charging system, allowing me to replenish the battery quickly. This means less downtime and more time enjoying my boating adventures. Additionally, the battery's low self-discharge rate ensures that it retains its charge even during periods of inactivity, making it ideal for occasional boaters or those with seasonal use. Safety is paramount when it comes to marine batteries, and the LifePO4 battery delivers in this aspect as well. Its stable chemistry significantly reduces the risk of thermal runaway, which is particularly crucial on a boat where safety is paramount. I feel confident knowing that I have a reliable and secure power source on board. However, the original lead acid charger did not work for this batteries and I have to buy new one designed for my setup (48v). You can buy very inexpensive charger if you don't care to charge batteries quickly, I usually use boat on weekends and my setup takes about 20 hours to charge 200Ah battery. Lightweight design of the LifePO4 battery, it occupies same space on my boat but has significantly reduced the overall weight compared to my previous battery. This not only improves the vessel's balance but also makes installation and handling much more convenient. I think the LifePO4 battery has proven to be an excellent investment for my boat. Its remarkable reliability, longevity, fast charging, safety features, and compact design have made it an indispensable component of my boating experience. I wholeheartedly recommend the LifePO4 battery to any boat owner seeking a dependable power source that stands the test of time. ... show more

  • Both batteries failed and refusing to charge or stay charged.
Style: 12V 50AH
I have regrettably purchased 2 of these thinking that all the negative reviews are in minority. Boy was I wrong. I had them less than 1.5 months in use. I come out 9.6 volts. I thought while playing devils advocate that "maybe" it was cloudy and "maybe" it did not get enough sun so I spent like 2 weeks diagnosing every single component only to find batteries fail and fail and fail. I would get them charged to full... come back 10 hours and voltage drops to 12.2 then in morning sun voltage drops to 11.8. This circus continued with me diagnosing every component of the solar until batteries were the only culprit. Right now batteries are refusing to charge at all. I can't even with these things. This is such a huge disappointment because I have designed my setup around the batteries. Now I am about to completely re-engineer everything. What a waste. ... show more

Batteries are extremely light and work great so far. I have been using them for a little over three months boondocking in a small travel trailer.

Won’t hold a charge . But the sellers customer service is great. I’d give it a five star on that part. They did everything they could to try and help me. Just happened to be bad batteries

  • Very good value.
Style: 12V 140AH
Excellent battery for the price. Benched tested 2 batteries and both provided 140ah+, with a steady 4 amp load. I did receive a defective battery, i feel it was mishandled by the shipper. Tech support (Eileen) was excellent getting me a replacement quickly. Should you need to return a defective battery contact the seller before following the Amazon return process, it will probably save the cost of shipping a battery back. ... show more
