Humsienk

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

So I bought this battery is tested and tried out! And it worked out terrifically perfectly! I need six more two more right away to complete my system I think to keep my air conditioner running for 12 hours and then I like to buy a few more for eextra power during storms and whatnot.! This battery worked out perfectly I can't wait to get two more and then four more and I'd like to try one to put in my golf cart! Right now I'm using it for my solar system for my refrigerator and my air conditioner but I only have one 100 amp hour smart battery obviously that's not enough! Terrific battery thank you! I almost forgot to tell you! If you go to will prowse on YouTube he completely takes the battery apart test it and everything on video in real time and tells you how good the battery is!

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.

Had a small problem but customer service took care of it for me other than that excellent

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.

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.

Been working great

I a. Impressed with these batteries. Great quality. And the company is amazing. Customer support is responsive and accommodating. Highly recommend. I will build out my entire battery bank with these.

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.

I’ve had 2 of these running for a couple of months on a12 volt solar system and they work great from 24/7 refrigerator to coffee pot vacuum cleaner and any other appliance we’ve plugged in

The product arrived on time and in perfect condition. The SOC was at 55% on arrival. The battery performs really well. Great quality! All cells were balanced! Thank you for the good quality Humsienk! Keep it up!
