BtrPower 12V 10Ah LiFePO4 Battery,3000+ Deep Cycles Lithium Batteries,Built-in 10A BMS,Perfect for Cyberpower UPS,Fishfinder,Lighting,Power Wheels,Lighting,Lawn Mower

I bought this battery for my Garmin fish finder on my fishing kayak. It’s very lightweight and fits perfectly in the YakAttack battery box. I’ve been using it for all my fishing trips over the past two months. I usually fish for more than 8 hours per trip—from 8 a.m. to 4 p.m.—with my fish finder running most of the time. This battery can last through more than four trips without needing a recharge, and it works GREAT. Highly recommend!

I've been using them now for 2 years and very impressed with the recovery rate and how much capacity they have. Use to have regular deep cycle and these are well worth the money in many ways. Extremely light, charge fast, will self store, still have the same capacity as when I installed them. You must use a battery separator and not an isolator. Research the difference. Some you won't need a DC to DC charger now but I bought one that will charge from the alternator or solar. About half the price now from when I bought mine.

I have mini Kota 12v 55lb thrust on 15ft mako skiff and this battery ran that trolly for 4 days without charging i average about 40 hours of fishing current was strong 2 of those days and tide change battery is def worth purchase cheaper now then when I bought it dont use regular lithium charger make sure it's lipo charger you won't regret buying this battery

I purchased a used 6x12 foot trailer and built my customized camper on it. Because I started from the bottom (wood over the trailer frame) up, I was also working to keep the total weight down so just about any vehicle could tow it (in other words, approximately 2K pounds). I had looked into the gel mat (AGM) batteries as they are cheaper ($189 to this one's $268 so $80 less but brother do they weigh a TON! Like 65 pounds to this one's 32 pounds, so literally twice as heavy! That is a comparison of 100 Ah batteries, so it's a reasonable comparison. I also have a 100 amp MPPT solar charge controller, 4 - 200W flexible solar panels, a 3000 watt pure sine wave power inverter, fuse box, cables, etc. When I can I will be adding another 100 Ah lithium battery, but for now, having tested my system, it is working great and of course, the battery is the heart of the off-the-grid system and this one is working perfectly. I should explain that I have propane to cook on a dual burner, also for the tankless hot water as I did include a small, step in shower stall next to the galley so I have hot water for both washing dishes and showering. I do have a small 12V refrigerator/freezer that is very thrifty on power usage and of course LED lights and a 12V fan, so for the moment, this 100 Ah battery will work for me, but when I have the funds, I will buy another one of these - it's a great price for this Ah capacity.

I have built 3 solar stations for backcountry yurts, primarily for lighting. The all-in-one systems are very expensive for what we need and would lead to excessive use for non-target charging. After a 'demo' period using some SLA deep cycle batteries proved that at 8,000' with cold winter temps and near constant use to again power LED lights, the SLA batteries died (3-4 years). I believe these, at 2x the cost, will outlast the SLA lead acid batteries by 3-4x. We also use the solar systems for charging our equipment (12 V) and for use with power tools when we have to do projects. The yurts are 1-2 miles in on hiking trails, so weight was also a consideration. Using a 500 W inverter to charge 18 V batt op power tools works great, and coupled with 50 W solar panels we've not seen the charge drop much at all. Overall just what we needed. Longer life, lower weight, and easy form factor compared to SLA lead acid. UPDATE: The first of 3 has died, after durn near 2 years use. $150/year is not good. The SLA used batteries I had used previously were a better value at this point. I had to replace this battery as it was in service, and I expect the B+#(~]Ii replacement all in one (about the same price point now) to perform better, and has a 2 year warranty.

I've waited a while to review to see how these batteries hold up. I have 3 in parallel and they are champs. Charge with no problems with 1.6kw of solar. I see no degradation in the batteries after many months of usage so far

I use a BiPAP with a fairly high pressure setting, 20 over 16. My machine does have the ability to run directly from 12 volt without a humidifier. This significantly reduces the power requirement. For several years have used two 135 amp hour marine cell batteries. At one time I might be lucky if I got four nights of sleep from one of them. On my most recent trip I only got one night from the 3-year-old battery. When I bought this 140 amp hour battery, I felt that I would be delighted if I got seven nights of sleep. Well, last night I just finished my 13th night averaging about 9 hours per night and the battery is still not dead. If I get a 14th night which will be tonight I need to charge it tomorrow anyway so that I can leave on my trip the next day. It's half the weight and I will only need one battery now.

I purchased 2 of these batteries for my trolling motor, 1 of them is working fine the other one made 2 trips and quit ,cannot get any response out of the manufacturer for a refund :(😡
