The slider is solidly constructed and even has fixing points that match most water bottle mounts. No drilling holes or adding additional brackets to make it work! 👍 Every cell in the pack is fused. Cell level fusing, means in the event of an internal short circuit in the battery (which the BMS cannot protect against), then all that will happen is that some sacrificial links will safely open, preventing any of the cells or cabling from overheating and becoming dangerous.
