Humsienk 12V 100Ah LiFePO4 Battery with Bluetooth-FAQ

What devices or applications is this battery suitable for?

This battery is perfect for a wide range of applications, including RVs, marine use (boats, trolling motors), off-grid solar systems, home backup power, golf carts, electric vehicles, and DIY energy storage projects. Its lightweight and long lifespan make it a superior replacement for traditional lead-acid batteries in camping, van life, overlanding, and emergency power solutions.

Can I connect multiple batteries together?

Yes! Our LiFePO4 batteries are designed for series and parallel connections to expand voltage or capacity:

Series Connection: Up to 4 batteries can be connected in series to achieve 24V, 36V, or 48V systems for higher voltage applications like golf carts and solar storage.

Parallel Connection: You can connect up to 4 batteries in parallel to increase the capacity to 400Ah for extended power storage (up to 20.48kWh total).

⚠️ Important: Always use identical batteries (same model and capacity) for safe and optimal performance.

Does this battery support Bluetooth monitoring?

Yes! Our Bluetooth-enabled version allows real-time monitoring via a dedicated mobile app (compatible with Android 4.3+ and iOS devices). The app provides detailed battery status, including:
✔ Battery voltage and state of charge (SOC)
✔ Charging and discharging current
✔ Temperature monitoring
✔ Cycle life tracking
✔ Protection status and alerts
📌 Tip: Bluetooth function works within a 5-10m (16-33ft) range. Ensure GPS permissions are enabled for connectivity.

What charger should I use for this battery?

For optimal charging and battery life, we strongly recommend using a 14.6V LiFePO4 charger with an output of 20A. Using an incorrect charger (such as a lead-acid charger with automatic desulfation) can damage the battery.
✔ Standard Charging: 14.6V, 20A for full charge in ~5-6 hours
✔ Fast Charging: Up to 50A (if your setup requires faster charging)
✔ Trickle Charging: 10A or lower for maintenance charging

Can this battery be used in cold temperatures?

Yes! Our low-temperature protection feature ensures safe operation in extreme weather conditions.

Operating Temperature: -4°F to 158°F (-20°C to 70°C)

Charging Temperature: 32°F to 122°F (0°C to 50°C)
📌 Tip: In freezing temperatures (below 32°F/0°C), the built-in BMS prevents charging to protect the battery. To charge in cold climates, consider a self-heating version or preheat the battery before charging.

Is this battery waterproof?

Yes! It features an IP65 waterproof rating, which means it is dustproof and resistant to water splashes.
✔ Suitable for outdoor use, RVs, boats, and off-grid setups
✔ Resistant to moisture and light rain exposure
⚠️ Not submersible – Do not expose it to direct water submersion.

How long does this battery last?

This battery is designed for 15,000+ deep cycles at 80% Depth of Discharge (DOD), meaning it can last 10+ years with proper care. In comparison, traditional lead-acid batteries only last 300-500 cycles.
✔ Lead-Acid Lifespan: ~2-3 years
✔ Humsienk LiFePO4 Lifespan:10+ years
📌 Tip: Avoid overcharging or discharging below 10% to maximize lifespan.

Does this battery have built-in protection?

Absolutely! The built-in 100A Smart BMS (Battery Management System) provides:
✔ Overcharge & Over-discharge Protection – Prevents battery damage
✔ Short-Circuit Protection – Ensures safety in case of electrical faults
✔ Temperature Protection – Prevents overheating and freezing-related issues
✔ Current Overload Protection – Automatically disconnects in case of excessive current draw (300A±50A cutoff)
📌 Tip: If the BMS disconnects the battery for safety reasons, simply wait a few minutes and reconnect.

How long does shipping take?

We offer fast 2-5 business day delivery from our local U.S. warehouses (CA, GA, TX), ensuring quick and reliable shipping.
✔ Processing Time: 1 business day
✔ Shipping Time: 2-5 business days
📌 Tip: You’ll receive a tracking number once your order is shipped!

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!

Can you please call me at [****] I need

Awesome battery. 110% recommend

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

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

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.

Been working great

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

I have two of these batteries and they work perfectly

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.

Great

Been working great

Humsienk is a very good company

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

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.

New purchase

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