Makita BL1890 9.0AH Lithium ION Battery by Vanon Obviously not genuine OEM or BL1830 ????

As far as I can tell Makita does not make a 9.0AH battery. The battery threw me off for a second because it said BL1830. I took the battery apart and it has 15x 18650 cells and one of those knock off unbalanced charging boards. Time will tell how long it will last. The 18650 cells are labeled Vanon.
