12.8V 100Ah LiFePO4 Battery Deep Cycles for RV/Off-Grid, Group 24

Great Great value LiFePO4 battery with useful Bluetooth app! I recently purchased the Humsienk 12V 100Ah 1280Wh LiFePO4 battery and I’m very satisfied with the quality. The build feels solid, it’s much lighter than my old lead-acid batteries (around 23-26 lbs), and it’s a perfect drop-in replacement for RV, solar, or marine use. What I like most is the Bluetooth connectivity and its own dedicated app (HumsiENK Smart app). Being able to monitor real-time voltage, SOC (state of charge), current, temperature, and other parameters directly from my phone is super convenient. The app connects easily and gives me peace of mind. So far the battery performs exactly as advertised — holds voltage well under load, charges efficiently, and the built-in BMS with low-temp protection works great. I’m really hoping it will deliver the long cycle life (thousands of cycles) that LiFePO4 batteries are known for. Overall, excellent quality for the price. If you’re looking for a reliable, smart lithium battery with app monitoring, I highly recommend this Humsienk model! value LiFePO4 battery with useful Bluetooth app!

This battery is a beast. I use it for my RV when we don't have AC hookup. I run lights, water pump, charge phones, ect. Refrigerator is propane. This battery will last at least a week before it needs recharging. Used it one season so far and it has been working flawless. The blue tooth monitor app works great and provides peace of mind knowing the battery charge status. I recommend it.

I have 4 of these now and intend on getting more as they go on sale for about $120 each being charged by my 12,000 watt solar panels and Mr Power MPP charger. Set up now in parallel outputting 12-14 volts to a 2000 watt modified sine inverter to power my 2 dead freezers. I have a timer on the 110 volt circuit to power freezers for 12 hours during the day and shut off saving battery storage for 12 hours at night. Freezers can be off for 2 days before showing any signs of defrosting. As I get more batteries I intend to output 24 volts using series/parallel battery connection and powering my 3000 watt pure sign inverter that I used to use 6 golf cart batteries to power. Their life was about 4 years and also were in my golf cart. They used to be $120 each but went to $150 recently so no brainer to go to a 10 yr Lithium battery that’s has more reserve power. The only issue is about the battery management system built into the battery to protect it. It does work as designed but what that means is that when the voltage goes down to 10 volts or so the BMS shuts the battery/batteries down and even if the load is removed they will not charge back up until you wake them up. You do this by applying for a few seconds a 12V DC input from a source like a Jump starter box. So this requires monitoring your system. I put a battery powered no AC alarm I got from Amazon on the inverter output to alert me when this happens. This occurs in cloudy weather. Yes there is a beep from the inverter but not loud enough to here in the house from the garage.

Excellent top of the line batteries and customer service. Had one battery malfunction and company replaced quickly and with great customer service. Thank you so much Chrissy

Died after a little over a year. Wont fully charge. Failed when it was needed. Liked it at first. Light weight and compact. Refuses to fully charge. Disappointing. Too late to return.

I have 650 watts of solar charging this battery and run 2freezers works great for last month

Hi, I've owned this battery about 6-months and have put it to work daily in my off-grid solar generation system. I've used it solo stand alone with my 12 volt inverter and I've used it in my sophisticated battery bank setups for a 24 volt inverter. In summary, this battery is of great quality. It yields great production and it wouldn't surprise me that the number of cycles they promise is true and therfore this battery yields tremendous value in the LiFeP04 battery 🔋 market landscape/space. The company and its engineering is very precise and no nonsense as is evidenced by thier labeling it a 12v 100ah instead of 12.8v 100ah as the .8 volts can really just be left off of all the batteries for a matter of practicality but it hints at the minds behind this dynamo battery product.

Got the battery while it was on sale, great price by the way. I unboxed it when I pull it out of the plastic bag I saw the case was all scratched. I hope this was not a return. Anyway I went ahead and put it in service and it seems to be working for the time being. It should be fine. 09/3/2026 Well, I have been using these batteries for about two years now and recently notice a change in the charge time. I did a capacity test and found that one of the batteries capacity had fallen to just 68 percent of the battery when new. I contacted Humsienk, that asked for certain information in which I provided. They promptly sent me a new battery with a smart bms. Great customer service and a great company. I will be buying more of there batteries in the future and highly recommend their products.
