This is the direct replacement for the battery included with the TC3.
36V Lithium-Ion Battery with Samsung cells, 9.6 aH capacity
Quick charging from zero to full in 4 to 6 hours
*Please note that TC3 and CS-240/CS-260 batteries are both forward and backward compatible in the 20" folding bike line-up. The current generation of batteries features an increased capacity from 7.8 aH to 9.6 aH. All 20" folding bike batteries come with the security key for the locking mechanism.
*Legacy customers with a CS-240 or CS-260 model should note that the USB charging port for auxiliary devices was moved from the battery to the display for the TC3 model. By purchasing the upgraded TC3 battery for your CS-240 or CS-260 models, you will lose the USB charging port functionality.
Please note that due to FAA and IATA regulations for Lithium battery content, battery orders can not be expedited for air travel. Orders placed before 1:00 PM CST are typically processed and shipped same-day with delivery expected in 3 - 4 business days.
