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 51.2Volt 100Amp 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.

I have 2 batteries for my off grid setup that has run 24hrs for 2 yrs. The quality is reliable
Reviewed in the United States on May 28, 2025 by Amazon Customer
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.

This my 3rd review. I thought the BmS was faulty because it only charged to 52 volts. I decided to to test it anyway , so I charged it up to 52 volts let it sit overnight and tested it at its resting voltage of 49.8 volts this morning, I was so surprised to see the results, it stayed steady between 49 and 50 volt for hours as I was averaging around 6amps then it stayed between 48 and 49 volts for hours. I pulled 4KWH and it was still at 48.3 volts. Its a great battery , its well built has good dual positive and negative connections.

I have had this battery for 1 year now. I am using Victron MPPTs with Renogy Solar Panels. After about 6 months, or about 300cycles the performance of this battery has dropped to about 50% capacity. Meaning the 100ah, is now dropped to below 50ah. The claim that these will last 4000 cycles is not true. I contacted their customer service and the response was to do several sequence of tests, which I spent four weeks on. After that, they said the deprecation of capacity is "normal". It would have been cheaper to just buy lead-acid batteries instead of these low quality lifepo4 batteries. They would have cost only a fraction. If you are looking for good quality LiFePO4 batteries, please do not buy these. They won't last even for six months. UPDATE: They took the both the battery back and refunded 90% of the money.

What isn't advertised is that this is a 15s battery, not 16s. Just about every 48v | 100ah battery these days is a 16s, which runs at a higher voltage and has more watt hours in the same form factor. Not only is this battery overpriced compared to those provided by other vendors, but you're also getting less capacity and cannot parallel it with other (vastly more common) 16s batteries without having to downgrade the entire array to accomodate the lower max charge voltage cutoff. I also emailed Litime support to test their responsiveness and register the warranty and I did not get a response back within 24 hours, which is unacceptable. I definitely would not purchase this (or any) 15s battery or any of Litime's products again due to the lack of prompt support. That said, the exterior build quality seems good - I will not open it because I don't want to void the warranty. The battery performs as expected for a 15s, but (again) you're paying more money for less capacity compared to other products on the market. Overall I'm giving this battery a rating of 2/5 stars.

If it wasn't the small posts or the bent handle on delivery , I would have kept these . The bent handle, the company says they do all this special handling and the damage must have been in shipping . It was packed very well . The box wasn't damaged .

Well, I suppose I should wait for the claimed 4000 cycles to write a review to confirm that this battery indeed lasts as long as is claimed, but in the meantime, having had it hooked up now for a few weeks, I am incredibly pleased with this battery. A world of difference from the AGMs I replaced with it, particularly not having to concern myself any longer with draining it. Charges quickly too. And great communication with the seller.
