※ If there are no purchases by the end of this weekend, I may reorganize the items for sale and withdraw the listings. Please be aware of this if you are considering a purchase. I can offer a small discount on this item. Thank you for viewing my listing. Please read the profile before purchasing. This is a used ROSSAM battery stabilizer CSR-300. Based on its size and specifications, I believe this model covers automobiles up to kei cars and motorcycles from scooters to mid-sized bikes. I had it installed on a 125cc scooter. After installation, I changed the headlight to LED, and I could feel that the flickering at idle was stabilized. The starter motor also started strongly. I couldn't feel any improvement in torque while riding, as it was a small-displacement scooter. There may also be a placebo effect due to individual vehicle differences. There are scratches and dirt from use, and the stickers/labels are peeling (I've reattached them now, but the adhesive is weak and they come off easily), but there is no damage to the main unit or cables, and there are no issues with use. Since I can't install it on my next scooter due to space constraints, and it's been over a year since I removed it and can't confirm its operation now, I'm selling it as a used, junk item. Please consider purchasing it with the understanding of this.
