Very Happy

Received my 12v 160Ah Plus battery, impressed before I opened the box, well labeled and very sturdy 2" foam top and bottom, no wonder it arrived safely. Ready to charge and install, manual and terminal hardware right there. Now the reason I chose the 160 Ah Plus having limited space two 160's gives 320 Ah that's like over 3 100 Ah battery's and at a good price makes the Humsienk 12V 160Ah Plus the clear winner, space, power, cost so yes I am going to buy another!!! THANKS!!!!!!!!

Excellent Battery — Exceeded Rated Capacity I recently purchased a Humsienk 12V 314Ah LiFePO4

Excellent Battery — Exceeded Rated Capacity

I recently purchased a Humsienk 12V 314Ah LiFePO4 battery, and I have been extremely impressed with both the battery and the service.

The battery arrived in excellent condition only 3 days after I placed the order. It measured 13.1 volts right out of the box. I fully charged it and then performed a capacity test. To my surprise, it delivered 328Ah—14Ah more than its advertised 314Ah capacity. That’s approximately 105% of the rated capacity, which is excellent performance.

This isn’t my first experience with Humsienk. This is the fifth Humsienk battery I own, so my recommendation is based on repeated experience with their products, not just one purchase. I’ve continued buying them because I’ve been very satisfied with the performance and value.

Communication with the seller was also excellent, and the exceptionally fast delivery was a big plus.

Based on my experience with five Humsienk batteries, I can highly recommend this battery and this company. I thoroughly test the batteries I purchase rather than simply relying on the specifications, and this 314Ah battery exceeded its advertised capacity.

I would gladly purchase another one and put it through the same full charge and capacity testing.

5 out of 5 stars. Highly recommended

Customer (United States)

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.

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

These batteries ARE GREAT!

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!

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.

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.

Awesome batteries

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

I can't tell you how happy I am with these batteries. They came well balanced out of the box, but I still connected them in parallel for a couple days to get the Voltage as tight and consistent as possible before installation. I used them in a small ebike car and they work perfectly. Humsienk is creating high quality batteries at an affordable price - and I hear their customer service is good too. Humsienk is seriously positioning themselves as a leader in the industry. If I need batteries again, I'll definitely be buying from them.

I want to start out by saying I really haven't had a chance to use this battery yet but as of right now it came shipped in good shape no damage I was able to charge the battery I was able to use it a little bit to make sure it functioned it did but when I get it into my camper and use it I'll be able to do a better review but as of right now everything seems great
