This battery is light weight and easy to install in my motor home. I’m ordering a second one to double my power. I am satisfied with this battery!

AmpereTime is one of the few brands of LFP that have a good enough internal BMS to permit 4x in series for 48v nominal systems needing more capacity…. and at a much better price. The 1C charge/discharge rate and LFP chemistry are perfect for off-grid Solar projects. Long life, no maintenance, more usable capacity make them a clear win over Lead. Only thing to take extra care with is not charging below freezing… which means they should be installed in enclosures that are protected from freezing, or disconnected from solar panels in RVs parked over winter in freezing environments.

Initially I just wanted to know if the lower priced lithium battery can meet my requirements, the answer is Yes, with a 2000w inverter and 400w solar panel, this 100AH battery could support my laptop and cellphone all day without any problems, actually I also use it to drive my coffee maker 1500w, great product!Realized that higher voltage will have lower ampere , it will reduce risks when using high power consumption appliance, I purchased 2nd battery of Ampere time, connecting 2 batteries in serious, with a new 3000W inverter, now the battery can easily drive my RV air conditioner for a short time to cool down the RV , the batteries are working great, even I discharged it to 1.7% of capacity, it was charged quickly second day , strongly recommend this product

Put the battery in my RV. Went boon dock camping miles from anything. Still don’t know what happened for sure. The generator was running and suddenly shut down. I checked the battery and it showed dead, nothing at all. I took the battery out and then found that there was blown fuse on the converter. I hooked the new battery up to solar system and the battery came back to life and was almost fully charged. I believe that the internal system in the battery shut it down and the solar triggered it back to life. It would be nice if this battery came with some sort of manual that explained the whole thing, especially considering the price paid. When you are out in the middle of nowhere it crazy to think you can make a call to their tech line. The batter does seem very efficient. It takes a charge quickly and holds it. Considering I replaced two golf cart six volt batteries for this very light battery it is remarkable. Time will tell how it all works out.

These are my first experience with Lithium Batteries. I’m using four of them to power my 2000watt inverter for the solar outfit I have put in my Grand Design 5th-wheel RV. I’m still amazed at how different Lithium batteries are from lead acid. At 71, the 75 pound lead-acids have become a problem to move about. These batteries are less than 25 pounds. I’ve tested all the devices in the RV except the AC’s (don’t intend to use them with the inverter), and when pumping out over 150 DC Amps I’m yet to go below 13 volts on my battery monitor. The price is certainly right, too. I’m not sure why people pay 400 dollars more for the others; I did notice that these are warrantied for 5 years, and perhaps its the number of charge cycles they’re rated for that make the others so expensive. I believe these are rated for 4000-6000 charge cycles from empty to full. They have an expected lifetime of 10 years. With four of them (400 amp hours), I doubt they’ll ever go much below 50% SOC unless I do a lot of microwaving and run the refrigerator from them instead of propane. Anyway, I am very pleased with what I’ve seen so far.Being new to Lithium and trying to figure out the settings on my Victron BMV 712, I emailed customer service with questions about five times. As regular as the clock, I had an answer promptly the next day every time.I suppose time will tell as I put them to work, but after a week of testing, I am very pleased. The only complaint I might make is that the bolt that comes with the battery is very short, half-inch I think. I wish it was a quarter inch longer which would make connecting two, 2/0-guage lugs to put the batteries in parallel a bit easier.

Lite, powerfull batt. Have been testing it useing a 3,500 watt inverter with power hungry tools & this batt has been flawless.Buy it!

For reference: in another system, I have 3: 100 ah BattleBorn’s – which I paid twice as much for and though I love them I personally can’t tell any difference with these ampere time batteries. In my off grid cabin, I have 4 of these Ampere Time 12v 100 ah batteries connected in parallel (400 ah, 12v) to (10) 100-WATT panels via a 40 amp MPPT controller… and I don’t have to think about them at all. They take a solid charge and last through the cloudy days with ease. This 5.2 KWH system runs my off grid lifestyle day after day without issue or concern. I’m running a full sized fridge, small microwave, toaster, instant pot and a few low power LED lights connected to a 3000 watt inverter and it is perfect – even in winter months when the sun rises low. The batteries take about a week to arrive, but show up flawless in good packaging and perform just as expected. I see the price fluctuate a bit as they find their place in the market, but so far, I can’t find a better value. Great product, and Battle Born finally has some real competition. If you know what you’re doing, I would definitely recommend. I’ve purchased 6 so far and no regrets.

These batteries have performed as promoted in every category.Shipping was fast, and Seller is very responsive.Packaging is good, and the batteries come with good documentation.Price is competitive, and with a 5 year warranty (which can be backed up with supplemental insurance offered through Amazon), I definitely recommend this product and this Seller.

I gave this battery a thorough test to confirm capacity and max current performance. I found that it exceeded the published specs. I got well over 100 amp hours out of the battery before dropping below 12 volts and found I could draw over 100 amps with no problem. This is an excellent battery for the price and weight.
