As well as the two downtube integrated options, the new 630Wh BT-E8016 becomes our largest external battery, coming with a new fitting port, the BM-E8016 battery mount.
To upgrade from a current 504Wh BT-E8010 external battery to the 630Wh BT-E8016 external battery you need to change the current battery mount to the new BM-E8016 battery mount. This is because the 630Wh battery requires a reinforced battery holder to accommodate the change in its physical size. You can contact your local dealer for more information.
Much like other SHIMANO STEPS batteries, the new BT-E8036, BT-E8035-L and BT-E8016 offer an extremely long lifetime. Even after 1000 full charge cycles (which would take 19 years of once a week charges to reach!) the new batteries will still hold 60% of their capacity. This means you can focus on the trail rather than on your battery indicator.
With these new SHIMANO STEPS additions you now have the choice of 10 batteries with either rear carrier, external type or downtube-integrated positions and faster-charging 418Wh or 504Wh batteries or extended riding capacity 630Wh options.
The new 630Wh internal BT-E8036 battery weighs 3.7kg, the 630Wh external BT-E8016 battery weighs 3.5kg, and the 504Wh BT-E8035-L internal battery weighs 3.15kg.
