Description

Qulbix frame expander set includes two 5 mm ABS distance rings and 20x M5x16 stainless steel TX25 bolts. The distance rings mount under the side-plates and widen the battery volume by 5 mm on each side, in total 10 mm. This set in necessary if you want to install 72V 40Ah or 50Ah battery packs, made of 21700 li-ion cells.

When installing the set take care of the sealing! The distance ring comes with a double sided foam sealer tape already on one side – this side adheres to the frame (remove the backing vinil before installation and press firmly to adhere to the frame). If the sealing is not done properly, the water might come inside the frame and could damage the electrical components. We do not take responsibility for poor sealing and damage caused by water.

You can order additional double sided foam sealer tape in the “Battery packs” menu.
