12V 100AH LiFePO4 Lithium Battery, 5000+ Cycles Deep Cycle LiFePO4 Battery with Built-in 100A BMS fit for RV, Home Storage,Trolling Motor,Off-Grid System,Solar Power System,Marine

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.

I used these on my Ryobi riding mower. I had to make a small adjustment to the bracket, but everything fit and connected without issue. Much lighter than the old batteries. They last a very long time and I can easily mow my 1/2 acre lawn. I only have to charge it once ever few mows, but even the, the charge has never been below 80%. It worked with the factory battery meter as well. Very easy. I did have to upgrade my charger since the factory one isn't meant for these batteries but that was easy.

I bought this for a 36 Lb thrust Kayak trolling motor. I have run it several times for short trips (It hasn't been warm enough for day trips yet), and it appears that this battery will run for a couple of days easily without charging. The motor I'm using draws a max 6.5 amps at max setting powering a 12.6ft tandem loaded with approximately 500lbs of gear/passengers. At the lowest speed at that load I'm drawing 3.2 amps with no appreciable loss in battery capacity trolling for 3 Hrs. consistently. I only ran max speed to test amps, and for this setup never moved above the first two speeds in a small reservoir with 8 mph cross winds. This battery nearly fills the rear compartment, but fits easily. At 17Lbs is a nearly perfect balance for my 22lb bow mount motor. So far I'm very pleased with this battery, and planning on updating this post with more info once I've had a chance to run it in river current, and for overnight trips.

I’m impressed with this battery. It’s much lighter than lead batteries and delivers excellent performance. I’ve used it for extended periods without any issues, and it holds its charge very well. Charging is fast. It works perfectly for my solar setup. It’s a reliable battery that performs better than expected.

2 years ago I put 2 of the 140ah btry's in my camper & I have had zero issues. They perform above expectations when boondocking. I just purchased 3 100ah btry's to put in my cousins boat. These are fabulous lifepo4 btry's, they are just as good as the top brand names without the high cost. The customer service is beyond reproach, I received one battery that had a cracked case, obvious damage in shipping as the box was heavily damaged in one corner, they immediately sent me a new one. Highly recommend this company & all of their battery's.

Like that’s it’s light and 100 amp,hours of usable power

These batteries initially test good but after a few weeks they fail, draining my entire battery Bank. Disconnect the BTR power batteries and the system will work properly again. I will never buy another BTR brand battery. I have a few of these now, maybe I can make one good battery out of the three bad ones. The seller will send you another one if it fails within the 30 days. I learned my lesson. I'm only buying siekon batteries now.

I bought one three years ago for my camper got into the solar bought another one paired with it. They’re amazing ended up buying a third for half the price I paid for the first three years ago. I’m a true believer their light easy to work with and last a long time on a single charge.
