Frequently Asked Questions

What are the exact dimensions and weight? Will it fit my existing battery tray?

The 12V 200Ah LiFePO4 battery has the following exact specifications:

Dimensions: 20.53 × 9.37 × 8.69 inches (521 × 238 × 221 mm)
Weight: 58.2 lbs (26.4 kg)

This is significantly lighter than a lead-acid battery of similar capacity (typically 100–120 lbs). Please measure your battery tray or compartment against these dimensions before ordering, as the casing may differ from standard group sizes like GC2, 8D, or Group 31. If your tray has extra space, you can use foam padding or brackets to secure the battery.

Does this battery have Bluetooth and a BMS?

Yes, this battery includes a 250A BMS (Battery Management System) that provides full protection against overcharge, over-discharge, overcurrent, short circuit, and temperature extremes. However, this model doesnothave Bluetooth monitoring. To check battery status (voltage, current, state of charge, etc.), you will need to use a compatible external monitor.

What is the actual capacity and energy of this 12V 200Ah battery?

The 12V 200Ah LiFePO4 battery provides 2.56kWh of usable energy (12V × 200Ah = 2,560Wh, typically rounded to 2.56kWh). Unlike lead-acid batteries, you can safely use over 100% of this capacity without damaging the battery, giving you more usable power than a comparable lead-acid bank.

Can I connect multiple 12V 200Ah batteries together?

Yes. You can connect up to 4 batteries in parallel (12V, capacity increases to 400Ah / 600Ah / 800Ah) for longer runtime. You can also connect them in series to reach 48V (four batteries in series) — but do not exceed 48V. All batteries should be identical, fully charged, and from thea same batch for optimal performance. No parallel communication cables are needed; simply connect positive to positive, negative to negative.

What size charger do I need? Can I use my existing solar system?

You need a charger with a LiFePO4 profile set to 14.2V–14.6V for bulk/absorption charging, with a float voltage around 13.6V–13.8V. The recommended charge current is 40A–100A (0.2C to 0.5C), with a maximum of 100A.

Most modern MPPT solar charge controllers (Victron, Epever, Renogy, etc.) and inverter/chargers work perfectly as long as you select the LiFePO4 or "Lithium" battery type. If your solar charge controller does not have a LiFePO4 preset, you can manually set the absorption voltage to 14.4V and float to 13.6V.

Important: Do not use a standard lead-acid charger with a desulfation or equalization mode, as the high voltage (15V+) can permanently damage the LiFePO4 battery.

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

Great fishing day

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.
