I have read about horror stories of people trying to return damaged batteries. I considered this to be cheap insurance against that.
About Shipping
- To improve service transparency, please note the updated process for truck shipments (LTL orders):
- After a large battery order is confirmed, we will send you an email to verify that you are ready for shipment. Once we receive your confirmation, we will request shipping quotes from our logistics partners on the same day.
- On the following day, we will confirm the final freight cost and arrange a truck pickup. The order will then be shipped as scheduled.
- The entire process typically takes about 48 hours, starting from the time we receive your confirmation.

Understanding Trucking (LTL) Delivery Progress and Tracking
Frequently Asked Questions
What are the environmental requirements for installing a wall-mounted battery?
To ensure optimal and safe operation, follow these guidelines :
- Environment: Choose a clean, cool, and well-ventilated area, away from direct sunlight and flammable materials.
- Ambient Temperature: The ideal operating temperature range is between 0°C and 45°C (32°F - 113°F) for charging. Avoid using the battery in extreme temperatures.
- Space: Maintain sufficient clearance around the battery as specified in the manual to ensure proper heat dissipation and access for wiring.
- Wall Strength: Ensure the wall can securely support the weight of the battery.
How do I connect the battery to an inverter?
These 48V batteries are designed to work with inverters rated for 48V battery banks.
Is communication necessary?
Connecting communication cables (like RS485, CAN, or RS232) between the battery and a compatible inverter allows for "closed-loop" communication. This enables the inverter to receive real-time data from the Battery Management System (BMS) for more precise charging and optimal performance.
How can I maximize the lifespan of my battery?
- Avoid Extreme Temperatures: High heat accelerates degradation, and charging at temperatures below 0°C (32°F) can cause permanent damage unless the battery has a built-in self-heating function .
- Use a Compatible Charger: Always use a charger or inverter with charging profiles specifically designed for LiFePO4 batteries.
- Optimal Storage: If storing the battery for a long period, charge it to 40%-60% state of charge and keep it in a cool, dry place. Check and recharge it every 3-6 months.
- Regular Use: Periodic full charge/discharge cycles can help the BMS calibrate the state of charge reading for better accuracy.
What are the rules for connecting multiple batteries in parallel?
Most wall-mounted batteries support parallel connection to increase total capacity (e.g., from 5kWh to 15kWh). When paralleling, always use batteries of the same brand, model, and age. Use cables of the same length and gauge for each battery to ensure balanced charging/discharging. Adhere to the manufacturer's limit on the maximum number of parallel units.

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

Been great so far! I want to get another one.

After a slight issue with the first battery HumsiENK got me a new one shipped right away. With just a couple e mails this company wasted no time getting me up and going. Great costumer service and what an awesome product. This 150ah battery has transformed my icon 6L into a long range machine. We use the cart more now than we ever have. Really helped in the hilly terrain. Came home with 4% battery left and the cart was performing like it was still fully charged. (Not that we make a habit out of fully depleting the charge).

Great
Plugged it into my system right off the truck powering the inverter in minutes.
Thank you all.

This seems to be a very Good Battery.
I have had very cloudy skies since I installed the
battery. But seems to charge faster then the other two batteries beside it.
It has been working Flawlessly since it was connected to the system ten days ago.
I am Happy with its performance at this time.

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.
K
Been working great. I have 2 and plan on getting 2 more

I have two of these batteries and they work perfectly. The only issue I have had is with shipping. Both batteries arrived damaged, one was damaged much more then the other. The company was quick to offer a discount in return for keeping the batteries.

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.

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.
