Humsienk offers great value
Humsienk offers the most available Watt Hours in a small footprint battery. It is an excellent value and performs extremely well for our RV needs. I highly recommend this battery.

We are absolutely thrilled to hear that the battery is delivering excellent value and keeping your RV adventures powered up smoothly. Thank you for highly recommending us to the community!

Excellent Customer Service
Many times, when you buy a product, it becomes very difficult to find a company that truly takes the time to respond and provide genuine customer care. My experience with Humsienk was completely different. From the very beginning, I felt respect, good communication, and a real willingness to help. Every time I had a question or needed information, they did their best to keep me updated and assist me in a kind and professional way. That kind of attention really makes a difference, and it is something that is truly appreciated nowadays. Experiences like this are the reason why I continue to trust the company and recommend their products to family and friends. Thank you again to the Humsienk team for the attention and support provided. I wish your team continued success.

Dear Osmany,
Reading your review truly touched our hearts. Thank you so much for taking the time to share such a beautiful and thoughtful message! 🌟
You made an incredibly fair point—nowadays, genuine customer care can be hard to find once a purchase is made. At Humsienk, we strongly believe that selling a battery is just the beginning of our relationship, not the end. Treating our customers with respect, kindness, and keeping you well-informed is simply how we believe business should be done.
Knowing that we've earned your trust, and that you are willing to recommend us to your family and friends, is the absolute greatest reward our team could ask for.
Thank you so much for your kind wishes of success—we wish the exact same to you! If you ever need anything at all down the road, you know your Humsienk family is always right here to support you. Have a wonderful and blessed week! 😊🔋
I do not recommend it to anyone.
I ordered a battery that arrived defective. When I tried to contact customer service, I first received a few messages from a bot, after which they tried to make me open and service the battery myself without any experience, which would also void the warranty. Since I did not agree to this, I have demanded a new product or a refund for the result of the problem. I waited 6 days for a response to the previous message and now I have had to wait 4 days for a response again. Really substandard customer service, and I do not recommend it to anyone.

Dear Customer,
We are deeply sorry for the unacceptable delay and the completely wrong advice you received. Please rest assured: we do not expect you to open or service the battery yourself, and your warranty remains fully intact.
Our management team has taken over your case. We want to process your full refund or ship a brand-new replacement immediately.
Please email us directly at support@humsienk.com with your order number, and our manager will resolve this for you today.
Sincerely,

Excellent service.
Ordered two LiFePO4 batteries, each 12 volts and 100Ah with Bluetooth. After three months no Bluetooth connection with one battery possible. After consulting the customer service and technical assistence of Arrow and Wynona to solve the problem, a new battery was sent. Both batteries now are functional and performing in a RV. Thanks to the HumsiENK App on two cellphones I can teach friends and fellow campers how to use LiFePO4 batteries.
Special thanks to Arrow and Wynona.

4 48v-100ah lithium
After purchasing 4, then 2 more 48v-100A batteries and had some small issues, the service support was outstanding! I'm off-grid at the moment and have been extremely happy with the performance of the batteries in supplying power to our temporary housing, a 45ft RV. Initial purchase was via Amazon and I've had these in operation now for about 7 months now.

Capacity tested Humsienk 314Ah 200A BMS Smart Mini…
I purchased a 314Ah 200A BMS Smart Mini LifePo4 battery for my Rapido 410 motorhome and it's charged from an MPPT Solar charger (400W), a DC DC charger and a 230V charger when plugged in.
I have just concluded a full capacity test of it using a 2000W Pure Sine Wave inverter running a 1Kw fan heater from 100% right down to 0%.
It achieved a total of 318Ahr as measured by my Victron SmartShunt and might have given a bit more except that I switched it off before BMS shut down the battery, as the voltage was dropping quickly.
I am absolutely amazed by this Humsienk battery and would definitely recommend it. The price was right and it delivered what it promised.
I have done a video showing the full capacity test on my YouTube channel (Rapido410) which is not sponsored.
I also love the app that gives you all of the data about the battery over bluetooth - temperatures, cell voltages and alarms etc.
During the winter, I did see that when the temperatures were below freezing that it turned off charging so that was a good safety feature.
If installing any LifePo4, always remember to add your own ceramic fuse to the positive terminal - never rely completely on the BMS, even if it's as good as this one.

Lithium batteries.
Do not buy from this seller. If the product doesn't work for you, it takes forever for them to provide you return labels. Once confirmed they've received the product back, they do not give you your money back.

Absolutely amazing customer service
Absolutely amazing customer service, my questions were answered within 5 minutes. And the 314Ah Mini Smart battery I bought is really great. I tested loading it with a 2000w inverter at maximum power and 170A discharge current, and the battery lasted 2 hours. Quite a performance for such a small battery, the battery is not much bigger in dimensions than a basic car battery.
