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

You can do no better than this company! I had what would have been a very minor issue to anyone who knew anything about batteries (which I don't), so I contacted their customer support. Eileen there was helpful, dedicated to helping me. And VERY knowledgable. I'm so very pleased with BTR!

The battery was delivered on time. The battery charges up to 13.6 volts. I thought that it would go up to 13.8 volts. Others have told me that not every battery will charge to that voltage.

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.

These Batteries are awesome. I got two 100amp hour ones to run a 24v trolling motor which they did all day no problem.I have since bought a 40ft cabin cruiser and use them for house batteries. They run both my diesel heaters no problem for 3 days and my smart bildge pump that turns on every 2.5 minutes and go off if there is no load. They also power my lectrasan sewage treatment system on both heads.They have never run out of power on my yet. I have no idea how close they are to low but I use them alot.They live in a battery maintainer at the dock. I abuse these batteries badly and they just don't care

Got this for my fish finder, but when i went back to get another they had changed the case on their 10Ah battery to black.. i tried to get them to make me another green one to match this, but i failed to convince them. i bought the black case version but I would have been happier if I could have the green case to match this one Maybe you can convince them the green case really looks great.

So far so good, it holds it's charge and works perfectly for my camper. However I did have to change my battery box on the camper. You might suggest the correct box when purchasing.

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.

Great customer service! But not great for what I need it for.When first purchasing this battery the battery itself you could hear something moving inside and when it was placed onto a charger it stopped reading or showing a voltage. After contacting them Eileen was helpful and prompt at helping me replace the battery.This battery really wants a 14volt charge and the solar system that im using is often only 12 to 13 volts, so if you're wanting this for solar you need a more powerful system then the one im currently using. So while the new battery works I do have to charge it with my generator rather then my solar panels if its even a bit cloudy.
