Envio perfecto

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).

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

Very good quality, definitely the best brand to buy!

Batteria top la migliore in tutti punti di vista. Azienda seria puntuale
Ho acquistato una 24v 320 e potente non molla anche con carichi elevati

Works well . Will buy again

Ok

So far great battery is do big and hooked up with my other one. Took 4 day to charge up. That's fine by me.
Now as of today they are at full power and kicking butt.

todo bien gracias

I converted my 24V RV power power system from 8 6-Volt AGM batteries which weights 420lbs, 200Ah usable energy, to this single battery that weights 107lbs and 320Ah usable energy. It also takes half the space, and with Smart Monitoring I can monitor battery status. No brainer decision to convert from AGM to Lithium. Shipping was prompt, product form factor was perfect for my application, and the price was drastically lower than any other brand I could find. When I pull the trigger to convert my home for off-grid operation, Humsienk will be by go-to source for batteries.

Great lifepo4 battery with very good capacity. Only downside is I cannot get into the advance parameters of the bms setting so that I can set it up how I'd like. If there is a way to get into advanced settings so I can choose the maximum charge limit and minimum discharge limit I would like to be able to access that if it is avaliable, otherwise it is a pretty good battery. I reccomend!

Excellent!

These batteries look Gr8!! My husband installed in our trailer conversion - we found out they were fully charged @ 26.4v out of the box. After a clean and expert install, they both tested excellent - we're happy with this buy =) we'll buy again if need too for another project, thanks, keep being a blessing!!

Hhhh

After a fair bit of research, selected this unit due to good reviews and price, Vendor was great to deal with and documentation is very good. Video review showed it had solid construction (guessing the same manufacturer as a couple others as well). Waiting to hit the water to see how it performs but charged up well.

thanks to the built-in BMS that protects against overcharge, over-discharge, and short circuits. I’ve noticed significant improvements in the efficiency of my solar system since switching to this battery. It charges quickly, lasts long, and is incredibly reliable.
