Customer Approved: Watch the Slim Fit in Action
Yes. The battery comes with 4 mounting brackets and 7 pairs of mounting holes for vertical, horizontal, or wall-mounted installation, making it ideal for RVs, marine compartments, and space-constrained energy systems.
Yes. The built-in 100A BMS includes low-temperature charging protection that automatically stops charging below 32°F (0°C) and resumes at ≥41°F (5°C), preventing cell damage and ensuring reliable cold-weather operation.
You can charge it via AC-DC charger, solar panel + MPPT, vehicle alternator + DC-DC charger, or generator. Charging time varies by method—for example, a 14.6V 20A charger takes about 5 hours, while a 40A DC-DC charger can complete a full charge in around 2.5 hours.
This is the perfect battery for my needs. I had hoped to find a smaller slimline battery, perhaps at 60aH, but am glad I got this one. I can add more options to power as the need arises. I’m using this battery in my 1995 Subaru Sambar “Kei Truck,” which serves as my mobile ham radio shack. It powers a 100 Watt Yaesu 891 High Frequency transceiver, a Yaesu ATAS-120 automatic tuning antenna, and a Yaesu FTM-150 RASP VHF/UHF transceiver. I later purchased a LiTime 1000 Watt Pure Sine Wave Inverter, which in turn provides power for a MacMini M4 computer, an SDR Play receiver, an 8”computer screen monitor, and a Starlink Mini system for mobile Internet access. It’s all working together seamlessly, much to my pride & satisfaction. Thanks LiTime!
When they arrived, I was surprised by how large and heavy they were. Yes, I had the dimensions and weight, but it didn't really settle in until I had them in my hands. They are ruggedly built appear to be well designed and will still be fine for my application (bed system for a full sized truck - CIGS 200W panel on the top of the shell and 2Kw inverter toward the rear of the bed). 4 stars, only because they are larger & heavier than I'd imagined. Have had very good luck with LiTime products so far, expect same from these.
This thing is great. Fit where I needed it to and powers my stuff just fine.
We have a smaller Class B RV and storage is always a battle. Our old lead-acid batteries took up a huge under-seat compartment. I was thrilled to find this LiTime 100Ah slim model. At only 2.36 inches thick, we were able to mount two of these bad boys vertically against an interior wall of a pass-through storage bay C a space that was previously too shallow for anything substantial! The 20.87" length fit perfectly along that wall. Installation was a breeze because we could choose the best orientation. Now, the original battery compartment is all free for gear! The LiTime app is super slick too; I connected via Bluetooth and can check our state of charge, voltage, etc., without having to contort myself to see the batteries. It's a total game-changer for efficient RV living.
Seriously impressed with the engineering here. A 100Ah lithium battery this thin is a testament to innovative design. Perfect for anyone dealing with challenging space constraints in their vehicle or DIY project.
Game changer for our RV. This slim battery fit perfectly in a shallow compartment under the dinette that was useless before. Freed up so much space where our old bulky battery was.
Space on a sailboat is beyond precious. I'd been trying to figure out how to add more house bank capacity without major modifications. This LiTime 100Ah slim battery is a marvel. Its 2.36-inch thickness allowed me to install it on its side, flush against a bulkhead in a narrow channel under a settee that was previously just wasted space. The dimensions (20.87" long) were perfect for that spot. The versatile mounting options were critical here. Now I've got an extra 100Ah without losing any locker space. The LiTime Bluetooth app is also fantastic for a boat C I can check the battery health and charge from the nav station instead of having to dig into a locker. This is a well-thought-out battery for marine use where slim and flexible installs are key.
I had this one awkward, narrow space in my van conversion I wanted to use for a battery. Nothing fit until I found this slim model. Its amazing how thin it is for a 100Ah. Problem solved!
