Humsienk 48V 100Ah 5.12kWh Wall-mounted Bluetooth LiFePO4 Battery with Active Balancing & LCD Touchscreen

I pre-ordered these with the assurance I could schedule the shipping so I could be there to receive and move the batteries. Unfortunately, the batteries were shipped without being scheduled. This led to trying to hold at a FEDEX office so they wouldn't sit for porch pirates, which turns out the FEDEX office doesn't allow lithium batteries, so multiple contact attempts and finally able to to work out a delivery with FEDEX about a week later. The batteries themselves were packaged very well and seem to be fine (I've only had them for one week).

Todo llegó en muy buen estado en un tiempo récord.
Estoy muy contento con mi compra ninguna queja recomendado este artículo un 1000% ojalá y todas las ajencias de EEUU brindaran un servicio así

I have not had the opportunity to use the battery yet !! From what i can tell it seems to be a great quality battery . The experience with the order and shipping was good !!! I actually plan on ordering another in a week if the sale price is still on. I can only buy parts for my system as i can afford them so its a piece meal event !!!

i installed it in my house to provide me with power during emergencies. we started having alot of power outtage here in the last few years and we cannot rely on the grid anymore. something is going on and we must prepare before it is too late.

this battery has TONS of electricity stored inside. i can run my water pump, lights, computers, fans... everything! its totally silent and doesnt emit gasses like lead acid batteries. also the energy density is incredible and the price is very low. when the grid goes down i can continue to live like before. it totally reduced my stress and i sleep way better now knowing that i have not only a reserve of food, but electricity.

Product is as advertised. I’ve only self checked the batteries for now as I building complete 8KW off grid system and not done yet.

Used for my truck camper ( @gordie_the_galloper ) running a 60L fridge, inverter, Starlink, string lights and misc items (Laptop, phone, tablets et al)

It gives me 4 days of use down to 20%

Paired with a 20A ac charger for filling when back home. I now have a 150W fold-out panel with a PWM charger for the next trip to see if I can keep the battery topped up.

Diesel heater, toaster and maybe an air frier next

So far so good

Only disappointment is the Bluetooth only connects within 2m of the truck

Aquí les quiero dejar mi humilde opinión acerca de esta compañía, en los 34 años q tengo nunca avía visto una eficiencia tan grande en cuanto un servicio de atención al cliente , les doy un 1000 de 10 , la clase calidad que tiene sus productos es incomparable , soy de cuba y llevo en esto unos 4 años y desde q empece a comprar estos equipos me hablaron de la marca y todas las cosas que están en mi casa en cuba son de esta marca , en la casa de mi suegra también, de verdad lo digo esta gente si siguen así son el primer lugar en el mundo

Todo perfecto como se esperaba siempre 100% confiable

These batteries ARE GREAT! I purchased 2 of them, ran them in parallel in our camper. We went on a 4 day trip with 6 people in our camper. We out the batteries to the test. Water pump, all the lights you make it we ran it. At the end of our trip the batteries were at 95%! Holy crap for real! The Bluetooth feature is amazing as well. I checked the batteries often just cause and man am I impressed! Great batteries and features!

Can you please call me at [****] I need to buy a charger for the batteries I bought from your company what kind of charger I have to buy and is there’s a charger works on 12 volt

Been great so far! I want to get another one.

After a slight issue with the first battery HumsiENK got me a new one shipped right away. With just a couple e mails this company wasted no time getting me up and going. Great costumer service and what an awesome product. This 150ah battery has transformed my icon 6L into a long range machine. We use the cart more now than we ever have. Really helped in the hilly terrain. Came home with 4% battery left and the cart was performing like it was still fully charged. (Not that we make a habit out of fully depleting the charge).

Great
Plugged it into my system right off the truck powering the inverter in minutes.
Thank you all.

This seems to be a very Good Battery.
I have had very cloudy skies since I installed the
battery. But seems to charge faster then the other two batteries beside it.
It has been working Flawlessly since it was connected to the system ten days ago.
I am Happy with its performance at this time.

Finally got a chance to use our rv and came away happy with the battery we install this year. It is and does what was promised Bluetooth work great and does everything I need. I received and charged the battery a month before using it and it stayed fully charged.

Been working great. I have 2 and plan on getting 2 more

I have two of these batteries and they work perfectly. The only issue I have had is with shipping. Both batteries arrived damaged, one was damaged much more then the other. The company was quick to offer a discount in return for keeping the batteries.

Replaced 2 deep cycle batteries with this LifePo4 324MH bluetooth battery for our GeoPro trailer and it worked really great. We did buy a battery charger to get it to 100% as it came in at 57%. Once fully charged it powered our RV for the long weekend no problem and full recharged with our solar panel each day. It also worked well to charge our laptop in the RV with the inverter and didn't deplete the battery very much. The app works well. The only downside is you need to be near the battery for the blue tooth connection to the app to work and it seems to disconnect easily. Not a huge deal. Overall pleased. Will see how it works for longer boondocks stays.
