【3.84kWh】Humsienk 12V 300Ah LiFePO4 Battery – 200A BMS, 6000 Cycles for RV, Household, Marine & Off-Grid Solar

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! 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

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.

Great product and full of energy
I am happy with this performance
Great fishing day

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

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.

New purchase, so I cannot rate longevity. It’s exactly as advertised. Fast delivery. Really like the Bluetooth app.

I'm reviewing a 314 amp hour mini smart lithium battery
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

Came at 62% charge install went smooth as well as Bluetooth connection. 314ahbt 12v great looking battery

the packaging is not enough. the batteries are always getting beat up. so much that the loose bolts are making dents in the battery case. the battery themselves are very good and low price!

I was bit skeptical at first because I never heard of the brad before but I went ahead and ordered a 2 pack of the 320Ah batteries because they had a presale and got a good deal, unfortunately they were lost at delivery due to FedEx not following delivery instructions and after reading some of the reviews about lost packages from FedEx I think Humsienk should not use their services, UPS could be a better option, however, I did added shipping protection with my purchase. I contacted costumer service to let them know about the situation and Arrow was very responsive and arranged for a replacement package, I got them after few days and my first impression was how well packaged the batteries were, I did a quick test after a couple of days to check the state of charge and they both showed 13.19, 13.20 volts. Batteries seem well made and solid and so far they are working great. I give 5 stars to Arrow from costumer service and to the product quality.

I purchased because of the price, weight, and favorable teardown reviews. The kwh-to-weight ratio is the best I have found among LFP batteries of similar capacity.

The battery was directly ordered from their website and was promptly shipped; it arrived with a 13.20v charge (standard for shipping). Included was an instruction manual and 4 quality lock-washer bolts.

What a huge capacity battery. Heavy and built like a tank.

Works great so far. Hoping for a long life.
