HumsiENK 12V 300Ah (314Ah) LiFePO4 Lithium Battery,Mini Size,200A BMS with Bluetooth,15000+ Deep Cycle 300Ah Lithium Rechargeable Battery,Max. 4019Wh Energy for RV, Marine and Off Grid Applications

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!

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.

Very affordable good value battery. Installed our camper with new converter. It has a lot of capacity for the money. Only had it in for 2 days will do a follow up during camping season. Overall I like this battery and would recommend. Also bought 2 rack batteries from humsienk and the app works very well for checking battery SOC.

I already have a 2 pack of the Humsienk 12volt 100 AH and purchased two more to increase my battery capacity in a solar set up. Pro's are I bought these for the battery cells, so working as a battery I haven't found a reason to complain about them. These 2 new Humsienk's shipped with a different manual. The information in the new manual looks like its all there, but I prefer the older manual. It has better ease of use to attempt to reference it. The Older manual still isn't the greatest manual. So the quality of the manual and ease of use I rate mediocre. Its usable though. Its just attempting to reference 12 batteries in 1 manual. The old manual is attempting to reference 5 batteries. So the New manual gets confusing. To where I start wondering what battery do I even have? What page is the info Im looking for even referenced on?? So I am glad I have 2 copies of the old manual. For Instance Standard/Maximum charging for the 12v100ah: 20A/100A..I think this reads like recommended continuous charge amps 20..Versus 100 maximum. If "standard" means recommended and theres such a discrepancy between 20 and the 100 Maximum, you start asking yourself is 23.3 amps OK?? Can I charge that high?? Then it says "Cycle Life 6000@80% DOD.. Since recommendation is .2C, it would probably be 20 degrees C 0.2C 80% DOD. To help indicate the test conditions to achieve 6000@ 80% DOD. Which has alot to do with what happens at 0.2333C? Consider, hypothetically a 0.3C might cause almost no loss of cycles...But I digress.. Two, I ordered these batteries knowing the BMS is not bluetooth capable. But bluetooth capable BMS is a really handy feature if you need to accurately check your State of Charge. Its almost mission critical. So I HIGHLY recommend opting for a Bluetooth capable BMS battery, unless youre sure you dont need it. Overall they are budget friendly, but expect to take the hit in quality of the manual and a bluetooth less BMS. That fits my bill for what Im looking for.

Exactly as described. Only have had them a few weeks and have not installed in my RV but I have been playing around with a couple of different 400w solar panels and they are charging well

Light weight, need a lithium charger when you purchase the battery!

A very good product in terms of quality and price, made with high-quality materials. I will buy it again.

This battery was recommended by my social group as a replacement battery for my solar system. They were spot on. Battery life and functionality were increased, easy to install, and the price was much less than the other well known competitors. Size was not an issue it fit my compartment perfectly. I highly recommend. These do go on sale as well so watch the prices.
