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.

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.

Been working great

Humsienk is a very good company. I found the quality of these batteries to be very good. I reached out to them for some information and received answers to all of my questions. This is a company that can be trusted.

It’s more than I expected a good quality product and a great price
