    • Excellent Performance, One Year Into Use
Review Image by Timothy Walden Timothy Walden
We are a little over a year into using 2 of the 400 ah batteries in our fifth wheel, mated up to an inverter, battery monitor, and 740 watts of solar. The batteries arrived in exquisite packaging. After fully charging them with a smart lithium charger and then 24 hours wired together to equalize, I installed them and have been running them on many trips from a few days to 6 weeks. The performance has been outstanding and I ran a test with our inverter to see how far down these would discharge before the inverter kicked off. I pulled 805 ah out of these two batteries, running a heavy load, before the low-voltage cutoff on the inverter. That is very impressive. As expected, they also charge very fast, pulling 120+ amps through our Inverter/Charger when connected to shore power or generator. These batteries are excellent quality and I will buy them again for our next RV. ... show more

    • A great purchase for my RV
I went from 2 100 amp led acid batteries to this single 400 amp battery in my RV and it is a game changer! It isn't just 2x the power. I can now use 90% of the capacity without the voltage dropping and then recharge all the way to 100% in less than 8 hours without hurting the battery at all. I now use battery for the microwave and induction stove. If I wake up and we are down 160 amps, that is no big deal. Driving will but back 40 amps and fully recharge it within 4 hours. Shore power or the generator can do 2x that so just 2 hrs to a full charge again. And get this, with an A/C soft start, I can now run my RV air-conditioner for up to an hour without the generator! This battery is a perfect match for a 2KWh inverter and all the solar you can fit on the roof. Will never go back to lead acid or AGM batteries again. ... show more

    • Great performance!
I purchased two of the 400Ah 12V Ampere Time LFP batteries and have been using them for over 3 months. I originally had them connected in parallel, but eventually stacked them in a 24V (2S) arrangement. They have performed very well and I cycle them about 50% each day. Customer support has been responsive to questions although I really haven’t had any problems. It’s amazing to watch them absorb 2000 watts with no apparent problems, and power 250 watts all day and night. Unbelievably light compared to lead acid batteries, and especially compared to AGM lead acid batteries. ... show more

    • My 4th Li time battery - no issues
I have 4 400ah batteries in parallel and been running this for just over a year. They are in a controlled environment (basement conditions). No issues so far. I run them down to 20-25% in my system. Batteries come well packaged. No damaged. Look for the M8 bolts they are taped in the packaging.

    • Bad seller buy from manufacturer.
Careful with this seller. I received my 400AH battery in a used broken, litterly, case. After submitting pics, the seller agreed to replace. 2nd battery started failing within 2 weeks. The BMS turn the battery on and off randomly. After TWO MONTHS of providing tests and parameters to the seller they agree to replace the battery but require the shipment of the failed battery back to them. I found out that shipping a faulty lithium battery is illegal. Seller won't help any further unless I ship a battery illegally...Buyer beware from this seller. Two bad batteries seem awful suspicious.. ... show more

    • Great product
Customer service was wonderful. They kept in touch until the battery arrived and then contacted me one more time to make sure I was satisfied. I was, the battery is great. I will definitely use this seller again. Very satisfied with the entire experience.

    • I wish every company had this kind of customer service that Nikki provides
It hope to sail these batteries to the south pacific someday. I will not have a generator and will be completely dependent on the batteries. I need them to work. After dealing with ampertime I am very impressed and am confident I could get whatever support I needed. My experience has been so positive I would buy whatever they sell. (I had all kinds of edge case questions for them, and they very patiently answered them over a long period of time.) I wish all my vendors for my sailboat gear had this kind of support. The packaging is wonderful. You feel like you are opening a laptop or phone. I got 3 batteries, charged them, and tested each one using a victron smart shunt and they contain the advertised amp hours. I watched Will Prowse on you tube tear these apart and the guts are of the same or better quality than other more expensive battery. ... show more
