I've used this for about a month, but no longer need it, so I'm selling it. My impression after using it is that managing batteries became much easier because it can handle 6 cells. Although this product has a fan, I felt it was better to use it in conjunction with a separate cooling fan. I'm including the separately sold cover (the white cover in the photo) as it is. Considering the price of the cover, I think this is a good deal. If you need more photos, please comment. Made by Reg Planning Pulse-type balance discharger 6 cells See the instruction manual for details. Products will be shipped from the available stock, and will be shipped in order of purchase as they are manufactured. After actually running it: It allowed for optimal battery management and efficient running when using mini 4WD batteries discharged to a specified voltage. You'll especially appreciate the convenience when running frequently.
