HumsiENK 12V 100Ah LiFePO4 Battery Lithium Deep Cycle, Group 24, IP67, Built-in 100A BMS, 1280Wh Energy, 15000+ Cycles for RV Solar Off-Grid Marine Trolling Motor, Portable Power for Camping

I purchased two of these 12V 100Ah LiFePO₄ batteries and they’ve been absolutely fantastic. The price is almost unbeatable for the performance you get, and the quality has been incredible so far. I run them in parallel to power both an AC unit and an inverter, and they handle the load with ease. They charge quickly, hold power well, and have shown to be very reliable. For anyone looking to upgrade their setup without overspending, these are a must-buy!

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.

Satisfied, works great

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.

bad battery Bought 2. One Stopped working after 3 or 4.. 1 to 2 hr uses I have many 100ah and 200ah batteries (0ver 20)of 2 other brands same 6a lifepo4 Chargers used on all. ....battery read full after too short a recharge time and doesn't power anything above 2a otherwise it stopped working on any higher draw because of low voltage output...my other batteries have been in constant use For over 4 years..no issues..sometimes after just 3 mins it dies company is getting back to me rather quickly to find an amicable solution battery seems to be working in some instances..

Tested many times in my kayak with 55Lb motor and it works perfect. around 4 hours continuously and the capacity remains around 85%. the weight is perfect and all the specifications from the manual are correct. I was using a charger for LIFEPO4 with 10Amps 13.2V of capacity for this 100A battery and works well. now I am waiting the original charger to have it with 100% efficiency.

Good product, quality for a good price.

My CPAP draws 7 amps and I can go 3 nights dry camping (no power), so I'm very happy. Because this type of battery holds voltage up as it is used the CPAP continues to run though the battery is drawn down to 25%. Lead-acid batteries don't do this.
