Frequently Asked Questions
Yes, absolutely. The Humsienk 48V 100Ah LiFePO4 is a drop‑in replacement for 8×6V or 6×8V lead‑acid packs. Its standard dimensions (20.47 × 10.51 × 8.66 inches) and 51.2V nominal voltage match most mainstream golf cart battery trays, including Club Car, EZGO, ICON, and Yamaha. No modification to your cart’s wiring or mounting is required – just remove the old heavy batteries, install this lightweight unit, and you’re ready to go.
Using the recommended 15A LiFePO4 charger, the battery reaches full charge in approximately 6.7 hours. Once fully charged, the 5120Wh capacity delivers up to 50 miles of driving range under normal golf course conditions – that’s more than double the range of a typical lead‑acid system, so you can play multiple rounds without recharging.
Yes, it is engineered for year‑round reliability. The smart BMS includes low‑temperature cut‑off that prevents charging below 32°F (0°C) to protect the cells from damage. The battery can be safely discharged from -4°F to 149°F (-20°C to 65°C) and charged between 32°F and 113°F (0°C–45°C). Once temperatures rise above the cut‑off threshold, the BMS automatically resumes charging – so you get dependable power even on cold mornings.Yes. Our rack batteries support CAN/RS232/RS485 communication, allowing them to talk to compatible inverters (e.g., Victron, Growatt, Luxpower, Deye, Sofar, etc.).
You have two simple ways to stay informed. The battery comes with a built‑in LCD display on the top that shows real‑time voltage, capacity percentage, and fault warnings at a glance. For more detailed data, download the Humsienk Bluetooth app– it connects via Bluetooth 5.0 and gives you mobile alerts, historical logs, and full control over settings like low‑voltage cut‑off and temperature monitoring. Both methods work 24/7, so you always know exactly what’s happening with your battery.
Yes, you can connect up to 4 units in parallel to build a 48V 400Ah system with 20.48kWh total energy – perfect for extended range or high‑power applications. When paralleling, ensure all batteries are from the same brand, have the same capacity (100Ah), are fully charged before connection, and are purchased within a 3‑month interval to maintain BMS compatibility and balanced performance. Series connection is not recommended for 48V systems.
This 48V LiFePO4 battery delivers excellent performance with 500A peak capability. Customers praised it as "plug and play" with easy installation. Reviews highlight quick shipping, great value, and strong compatibility with various inverters. One customer noted responsive customer service that resolved a small issue. Overall highly recommended.
I’d like to give 5 start but the battery arrived damaged. Not the fault of Humsienk but the process to get it taken care of was a little concerning. I did purchase the “worry free” delivery policy which took care of the cost but at the same time I may not have a warranty on the battery itself now. Everything seems to be working fine so far.
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).
Just received my second 48v golf cart battery and it arrived on time and undamaged. The box looks like it just came off a showroom shelf somewhere. My thanks to both Humsienk & FedX for their handling & delivery of both batteries. if I can figure out how to post pictures I will show you how well it arrived &the fantastic job of packing
Great product
I recently installed four Humsieng 48 V 150 Ah lithium batteries (configured as a 48 V, 600 Ah bank) to pair with my EG4 12000XP V2 inverter, and the performance has been outstanding. These batteries deliver stable voltage, strong discharge capability, and excellent runtime under real household loads.
Electrical Performance
• Nominal capacity: 150 Ah per battery (600 Ah total in parallel)
• Usable energy: ~28.8 kWh total at 48 V
• Voltage stability: Holds voltage extremely well under load, with minimal sag even during high‑demand events
• Charge acceptance: Smooth charging curve with predictable behavior when manually setting charge parameters on the EG4 inverter
• Peak discharge: Easily supports whole‑home loads through the 12000XP V2 without any instability

Not installed yet but happy with response, shipping, and packing. Get everything that I purchased in ready to install condition. Thank you!
It was exactly what I wanted
Great battery
Great, i use them on a solar battery bank and they do great ballanced out good 0.004 cell diffrence and thats great
Quick shipping inside USA. Excellent product. Just plug and play
Had a small problem but customer service took care of it for me other than that excellent
Great battery life. 1000 times better than a traditional acid battery. Easy install as well.
It a great value for the price.
They work well!
Battery arrived quickly, well packaged, charged up well. With 500amp capabilities makes it very strong and works well with my 48v inverter, as well as Bluetti ac200L and Oupes Mega 1. Need to buy more!
So far really freaking good. Had the battery installed in my 2016 club car tempo. Replaced the dying lead acid batteries.Really straightforward install. Had to cut some things out of the way and prop the new battery up a little to accommodate the wiring underneath. Probably took a couple hours (and I’m an idiot) after watching a YT video. Noticed an immediate quickness/torque boost and gained about 1 mph top speed. The 150 amp/hr may have been overkill honestly as I’m using about 6% battery per 9 holes. My course is quite short and flat tho so I’d guess most people would use more. Price seemed reasonable. I’m happy with my purchase 👍
We swapped out x4 12 volt lead acid batteries in our Club Car Precedent with this unit. I am fairly mechanically inclined and did not find this to be difficult at all. I had to do some rearranging of some of the carts internal componets and some wire management. Nothing challenging. It took about 1.5 hours and the cart's performance improved dramatically. Only part I am not completely satisfied with is the little on board screen/monitor. It is dim and hard to see. Bluetooth connectivity was easy.
Works great, huge gain in distance and increased speed.
Works great carts run all day with no charge
Impressed with the service and delivery of the 48 volt golf cart battery I purchased. I was leary of getting such a heavy battery delivered, but Humsienk staff did a excellent job packaging the battery. The battery arrived undamaged, totally surrounded by high density foam , not even a scratch. My compliments to both Humsienk & FedX. I will be ordering another battery from them again soon.
An excellent battery, well built, works as designed and the value is outstanding. I would buy again.
Received my 48 volt battery last week and have started my solar installation in our RV. Have charged and tested battery output with no issues. Look forward to being able to boondock in our RV.
A very nice battery, easy to install
