LiTime 1000aH slimline battery & 1000W Inverter

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!

Heavier and larger than I'd imagined.

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 SLIM LiTime Battery Revolutionized Our RV Space!

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.

RV Upgrade GOLD - So Thin!

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.
