Features

  • Grade A LiFePO4 CellsLiTime 51.2V 100Ah Group 8D LiFePO4 batteries adopt advanced Grade A LiFePO4 Cells with UL certificated, which have higher energy density, more stable performance and greater power. Besides, the BMS with equalization to control the consistency of the cells inside the battery, which to extend the battery lifespan. It also with FCC, CE certificates, and a 5-year warranty will set you free from the battery security concerns.
  • Higher Energy DensityLiTime 51.2V 100Ah LiFePO4 with the higher around 53.38Wh/lb energy density, it is a 3-4 times that of lead-acid batteries in the same dimension. Lasting for around 4000-15000 cycles, which means it can be used around 10 years.
  • 10 Days Nonstop Power SupplyLiTime lithium battery can power your home for up to 10 days without using any utility power (Ensure the demand of min. electricity per day is 0.5kWh), allowing you to avoid grid outages. Meanwhile, with the 100A BMS and 5120W output, you can easily power most heavy-duty appliances at the same time, including dryers, air conditioners. It supports to be connected in parallel for higher power (Max. in 4P for 20.48kW).
  • 4X Charging Speed & 1/2 Space Saving LiTime 51.2V 100Ah LiFePO4 battery has a max. 5.12kWh energy, which is equivalent to 4*12V 100Ah LiFePO4 batteries in series (or even 8*12V 100Ah AGM batteries in series). It greatly reduces charging time from 20hrs to 5hrs (with 20A charging current), because you do not need to charge the 12V 100Ah battery one by one once you just receive the batteries, and it can save your 1/2 space.

    • Exceptionally Good for It's Price Point
Size: 12V100Ah
I bought two of these batteries (12V 100ah). First ordered one to test, satisfied I ordered a second. Both Received On-Time, Good Packaging. Extra terminal bolts provided each. Documentation is good, clear values for User programmed chargers. These are setup in series now to form a 24V 100ah battery pack. I opted to pay more by having two batteries rather than one 24V battery for a few reasons. As stated above, I was concerned with the quality and wanted to test one battery before doubling down for twice the expense. Second, these batteries have a battery management system which is internal to the battery. If it goes bad, chances are the battery will be useless. Having two go bad is unlikely. So I can always reconfigure my system to run from the good 12V battery. Finally, I have a lot of 12V stuff and having a pair of very good 12V batteries gives me more options. These batteries are well built, case seems generic but sturdy. Especially happy with the Terminals, they seem very firmly mounted to the case and hold connections tight. I've run several capacity checks on this, but the only full capacity test I made would be characterized as a .1C test. That is a constant discharge of 100watts, but in my case it was a refrigerator with defrost so when it did run it was about 110watts and about 330watts during the defrost cycle. I was expecting it to run about 39hours but it only made 32 hours. However, then I worked in the inverter efficiency (90%) and the vampire power used by the inverter even when it is not generating wattage. I did several different discharge tests and always got above 95% of the rated watt/hours. That is excellent considering the price point on these batteries in comparison to other similar batteries. I DO NOT recommend any PWM charger with these. I tried charging the battery with a Renogy Voyager and the pulses exceeded the max voltage causing the Battery's Management System to disconnect. Even though this Renogy charger has a LifePO4 setting. I contacted Renogy they were no help, I also contacted AmperTime and the good news is they actually responded. But I knew what the problem was and it simply was not a battery or Battery Management System issue. Needless to say I bought an MPPT charger, EPEVER Triron and it works great. But that is for another review. Couple more notes. I am shocked at how lightweight this battery is, they weigh about a third of what a typical flooded battery would. Every time I pick them up I am surprised by their lightweight. I am sure RV people will appreciate this. The max voltage I got on these batteries is 13.5V after it settles, I was expecting 14.4V. Without making this longer, don't worry about it. It is a weird charge curve and 13.5V is basically 99% charge. My discharge test confirm these batteries will perform to there approximate 100ah rating. In Summary, very happy, highly recommended and I did buy two, perhaps get more in the future. ... show more

    • Pretty nice and good support
Size: 48V100Ah
The first one arrived but the handle was bent in on one side. LiTime accepted the refund after I took a few pictures for them. In my opinion they need to have those handles removalable and reattachable so they don't get damaged during shipping. The second one arrived fine. Be aware these are designed for solar solutions and nothing more. There are not many standalone chargers that will operate at 54.75 volts and this has a cut off at 56 volts. I'm using this as an extended battery for a Eaton UPS and I did get it to work, but I have to have a secondary battery in the system as the Eaton will sent current to 57-58 volts. ... show more

    • Worked perfect with my RV solar system
Size: 12V100Ah
I had a deep cycle lead type battery and my 400 watts of solar just seemed worthless. Replaced with this battery and the solar fully recharges it by noon each day and the refrigerator runs all day and all night off of the battery. Only pulls it down to around 60% state of charge. So far I am extremely happy with it. ... show more

    • Impressive
Size: 12V100Ah
I wanted something reliable. I've spent so much time learning the things I need to know, and quite a bit of money for the best components I could afford. When it came to the batteries I wanted to get what are considered by many to be the top of the line, but frankly they are a lot more than I'd hoped to spend. I just can't reason why this many years into lithium battery development it should still cost so much to get a reliable and safe battery with a quality BMS. So I read the battery reviews on Amazon, which I love and rely on but always take with a grain of salt, and then I looked to some solar forums around the net. One in particular dated back awhile and everyone seemed impressed with Ampere Time batteries, and they all seemed way more knowledgeable than myself about it. At less than half the price of the highly rated ones I decided to bite the bullet and take a chance on what might end up being a weak link in my solar system where I really should have invested heavily. My battery order shipped the day after I ordered it and it arrived about a week later across the country from California. On first impression the box was nice and strong, and upon opening the box I found the battery completely secured and cushioned with thick and dense foam inserts. The paperwork, a large 10 page color brochure on the company/product brochure/product manual/and lifetime service card, all came in a thick clear vinyl zip case that reminded me of the type that comes with a new boat. The manual is in color with lots of graphics and is nicely readable and easy to understand. Few companies these days seem to give their product this kind of attention and I was already feeling like I'd made the right decision. The battery has a nice wide soft nylon strap across the top length of it to assist in carrying, even though it isn't a very heavy battery, which also made it easy to remove the battery from the box. Both 100ah batteries I bought were in perfect condition and both were charged exactly at 81%. I've only used them for about two weeks steady so far but they have been working flawlessly on a 600w 36v array with a Victron controller. I've ran a 8000btu LG window air conditioner on it with a 2000w continuous/4000w surge inverter, and I've ran things like a large side by side refrigerator/freezer, my 1250w inverter microwave, a 1500w portable infrared stove, and a large oscillating fan (not all at the same time). The seller has reached out to me more than once to ensure I'm happy with my purchase. Five stars because I couldn't be happier and I have no downside to report. My first impressions were high enough that I ordered two more 100ah batteries, for the max total of 4 allowed in a bank, to help me expand a little. I'm a real customer of this product and I wasn't compensated in any way for this review, if you found this review helpful please click the button. ... show more

Worked well for running iceco fridge. Shaded camp sites and two day rain event almost killed it while on road. Not charging fully before trip didn't help. However weather cooperated and 100 watt solar panel with victron mmpt brought battery to float voltage. Five amp rc charger had struggled to fully charge it. Overall, the case is solid and it is running fridge and media. Happy so far. ... show more

    • Love these batteries
Size: 12V100Ah
Ordered this battery to go with a previous purchase so I can test out a 24 volt setup as I hope to go to a 24v house bank in my sailboat. These are excellent batteries and the 3rd one I've bought from Ampere / LiTime in all. They are well made and do the job, support was quite friendly and helpful when I have contacted them. Excellent price for what you are getting with these LFP batteries. ... show more
