48V 314Ah (4 Pack 12V 314Ah) LiFePO4 Lithium Battery Max. 4019Wh Energy, 15000+ Deep Cycles,200A BMS with Bluetooth, Lithium Iron Phosphate Rechargeable Battery Great for RV, Marine and Off Grid

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.

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.

So far the 2 batteries i bought have worked well...my only gripe us that the ability to alter BMS settings is very rudimentary and you cannot do any custom fine tuning of the settings...a third party BMS cannot be used, so you are confined to using the very basic built in BMS application that comes with the battery...im speaking if the 314ah lifepo4 smart mini Bluetooth battery

I purchased 2 HumsiENK 12V 300Ah (314Ah) batteries. When I received them on of the batteries had a bad BMS, (faulty temperature sensor) and showed the battery at -40 F. I contacted the manufacturer for warranty and after a simple test and confirmation they sent me a replacement battery promptly. So far the new batteries appear to be working as advertised. These batteries replaced 4 existing 100Ah batteries thus only took half the space and increased overall Ah by 200. The only initial negative I have is that the bluetooth signal is very weak and you have to be within 3 or 4 feet of the batteries for it to work. Also the phone app will only let you view battery at a time.

Using this as a a huge battery bank to top off my Jackerys. At 4kw this battery will hep me keep all my many power stations charged. I charge this batter either through 400 watts solar or by using a 40a lipo4 battery charger. With all my planning I can go about 2 days off grid before I need to use the HumsiENK battery.

Installed in series on my travel trailer, great shape, arrived with over 13 volts. Will update if they pass out on me.

Good buy

Replaced two deep cycle marine with these lithium for hydraulic winch and tilt trailer. No loss of power noticed or issues.
