Thank you for viewing. This is the Hitec X4 Advanced II. It's a charger. I'm selling it to clear out my inventory. I purchased it in 2018 and used it at home to a moderate extent. I haven't used it much in the last two years. I have confirmed that it works for this listing. There are scratches and dirt from use, so please check the condition before purchasing. Recycled materials may be used for packaging. No returns. I am not responsible for any malfunctions after the product arrives.
