  1. Coastside Kirk

    I’ve been considering upgrading my RV coach batteries to LFP for some time waiting for the prices to drop. The seller offered a $100 off so I ordered a total of 4 batteries each on a separate order.Having just returned from a remote camping trip I can say from initial experience that these batteries are just what I needed. I have a 3000 watt pure sine inverter and ran microwave, coffee maker, hot water, and even the 3-way fridge for a while batteries never dropped below 12.8 during rest periods. My AGM battery bank voltage would drop under heavy loads and sometimes trip the inverter cutoff circuit. No drop outs with these guys.Before leaving I had just enough time to evaluate the capacity of one of four batteries. It measured 98 A-hr which was close enough to the 100 A-hr rating. The cutoff voltage for charge and discharge we’re spot on so I know the BMS working fine. I did not test for maximum discharge current. Something I’ll do in the near future.By the way compared to AGM batteries these are worth the 2x price. I wouldn’t have paid the 3x price from some other sellers though.One thing to be aware of is that the physical dimensions don’t line up with lead acid 100 A-hr batteries like Group 27, so you’ll likely have to make mounting adjustments.

    I gave it 5 stars because their customer support was super responsive and helpful in getting an issue rectified. We are using it as a trolling motor battery, and this might be overkill but it worked great and we wanted to not have battery/charge anxiety. 100 Amp hours in a 24 lbs package, amazing!

  3. Michael Hsu

    Bought this for a 55lb thrust GPS trolling motor and I’m really happy with it. I’ve only taken it out once and had no problems all day, had about 66% battery left after 7 hours of trolling around and spot locking in heavy current and winds. I also ran a load test on it and was able to pull 1279.21 Watt hours, which at a 12.8v nominal voltage comes out to 99.9 ah. At $500 with a $100 coupon, this thing feels like a steal. Time will tell how many actual cycles this can handle.

    Finally installed this battery in our RV, this battery is constructed of high quality materials and has performed well so far. Can’t beat the price with the $100 off coupon! This battery will outlast many others in the same price range.


    When We First Ordered Battery, it arrived Super Fast, but Problem with Mishandling of Package probably during package delivery, contacted seller who instantly resolved the issue, fast communication too. When the battery came in, also shipped quickly it worked Great, already had a full charge, tested it with voltage inverter and ran several devices, Tested battery voltage and ran very well. Its not very heavy for the Amps that it puts out. We are glad we bought it. Wouldnt mind getting a few more of these for backups. They have a super long storage life even at 20 Percent charge.

    Installed 2 of these to my camper with solar charger for more battery storage and long life. After only 1 week of course the system is doing great. Durability to be determined, but at the outset appears to be an excellent addition.

    I use deep-cycle lead-acid batteries with inverters to power public address systems (mixers, amplifiers, effects, lights, etc.) for music groups and other activities in areas and situations where power is not available. I also maintain an emergency backup power system for my home. While LiFePO4 batteries cost about 4-5 times cost of lead acid, they have several significant advantages. They are about half the weight. They can be recharged thousands of times instead of hundreds. They can be discharged to a lower level without significantly reducing their lifespan, and maintain a higher voltage throughout the discharge cycle. I expect to get more and better service for my money with LiFePO4.When my first BtrPower 100AHr battery arrived, I carried it around trying different 12 volt applications. Ham radios worked fine. Audio amplifiers and lights worked fine with a thousand watt inverter. 3/8″ electric drill worked fine. I wanted to see if it really had 100 Amp-Hour capacity so I ran five 100-watt light bulbs and an electric analog clock to track the time until the inverter shut down. Total time was about 2 hours and 11 minutes, which comes out to about 91 Amp-Hours (2.183 Hr x 500 Watts / 12 V = 90.97 AHr). The battery was not totally drained and still showed 11.2 Volts. I also weighed it — just under 26 lbs. I didn’t test the battery at greater than 100 amp output, nor did I test it for longevity (I just got it this month.) All in all it was good enough for me so I bought another one. I’ll be wiring a pirate ship (on wheels) for for music in a parade next week, and I won’t be using lead-acid.One last thing. The screw-on terminals are wonderful. You can attach cables to the battery with your fingers instead of a wrench. And they make a great terminal to hook up battery clamps.

  8. Handy Evenhanded

    I ordered the LiFePo 100 amp-hour battery. The one I received was defective. My voltmeter showed zero voltage. The battery refused to charge. I contacted the seller, who responded that very evening, promising to send a replacement. The replacement arrived promptly and appears perfect. Best response I’ve every experienced.Update: I’ve had the replacement battery for a couple of weeks now. I ran a capacity test by putting a constant load on it and monitoring the volts and amps with my Hall-effect multimeter. After five hours, the battery had provided 1154 watts. I stopped the test at that point because I saw no point in completely depleting the battery (it had drawn down to 12.13 volts). So 1154 watts divided by the nominal voltage of 12.8 gave me 90.1 amp-hours, and the battery could have given more. I’m satisfied that I got everything I paid for.

    This is my 3rd pair of lithium, and my second pair of LiFePo4 batteries. I have a bass boat and between trolling motors and multiple fish finders and enhanced transducers, I run a lot of DC on the boat. And before that, I was running on fishing kayaks, where the light weight and high power of lithium batteries are important.As you might guess, it is a constant battle with the wife on expensive “stuff” I buy just to go fishing, so when I added a third Garmin EchoMap Ultra and a second Panoptix LV32 to the boat ( 😀 ) and realized the two 50 Ah Lithiums I had been using were only getting me through a day and a half of fishing. ( I like to camp on the lake/boat for multiday trips over the weekend at my favorite spots to save on gas and wear ) So, I went looking for higher capacity batteries to replace my 6 year old 50 Ah’s without breaking the bank.I’ve been a steady customer of VMaxTanks, which have always been great batteries with spectacular customer service. So, when I found these 100 Ah batteries on Amazon at nearly half the price, I was skeptical, but I am a couple trips after the purchase and they are still going strong. I really notice no difference between these and the VMaxTanks 160 Ah’s I have on the 24V Trolling motor. They run the fish finders for the entire 2-3 day trip and recharge just as they should.I’ll try to come back at the 6 month to 1 year mark or if I have anything to add about these, but for the price, I am very pleased with these batteries! If you don’t see a note after a year from this post, assume they’re still going strong! (no news is good news and all that…)Oh, one thing I really did like, I had to buy wing nut terminals for the VMaxTanks from them for an added charge, but these came with big, brass battery terminal-like knobs. Nice and heavy to act like battery posts, or unscrew and insert your tabs to screw down connections. Really liked that! Though I haven’t run into any issues, you probably want to invest in some corrosion resistant lock washers if you’re using them in a vibration-prone environment like a boat to avoid loosening of the connections.

    I ordered 1 to see if it would pull full capacity and it did. So, I ordered 3 more at $309 ea. The Q&A stated they would operate in series at 48v. I am connecting thest to a Victron 3000kw 30 amp 48v system and will be doing more testing this week. I’ll update the review after but I’m happy so far.
