12V Battery

I have only had the battery for a few weeks but it exceeds my expectations so far ... it arrived in perfect shape - bluetooth is cool -price is good ! It is so much better and lighter then the the old battery . Planning for another one next year.

THESE ARE EXCELLENT BATTERIES. I'VE BEEN USING THEM FOR ABOUT A YEAR NOW SUPPLYING NIGHTTIME POWER, CHARGED BY MY SOLAR PANELS DURING THE DAY. NO PROBLEMS.

Great battery! Used for my trolling motor.

Love it exceeded my expectations.

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

Charger works well, no issues with ordering, delivery or operation. Charger comes with ring terminals, I replaced with clips as the battery moves between my boats and the charger stays in the shop. Easy fix but perhaps Humsienk could include clips with the charger.

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.

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

With more budget options available i picked humsienk because of reviews based on teardown videos on YouTube. Glad I did, these batteries are underrated and work great!! Even tested out customer service because of a shipping issue, and they respond right away!

It’s more than I expected a good quality product and a great price

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.

Happy

it is the best!
i use it in my camper and also at home coupled onto a normal power station. the bluetooth feature is amazing! i am currently building an electric bike and will also use it on there.

I’ve only had one chance to use this so far. It took a 300ah Smart battery from 50% to 100% capacity in a couple hours. Seems exceptionally well made. A good value compared to other more expensive brands that are very similar. It only lacks the Anderson connector’s on the charging wires. Install them after if required.
