GOUACH Bicycle battery 48V - 12.8Ah - 599Wh - Waterproof|Repairable|Solderless|Smart - BLACKPACK50 13S4P

The GOUACH 48V - 12.8Ah - 599Wh - Waterproof|Repairable|Solderless|Smart - BLACKPACK50 13S4P bicycle battery is made up of 52 lithium-ion cells. It was specially designed to be placed on the frame of an electric bike.

It is supplied with a support that screws in place of the bike's water bottle holder. Its robust plastic shell, rounded at the front, allows it to fit onto most bike frames.


Gouach is a Bordeaux start-up which won the first French Tech 2020 prize, as well as the TAIPEI Cycle Gold Aware 2023 for its revolutionary bicycle battery technology.

Gouach has created a solderless, cable-free bicycle battery system, modeled on Lego blocks, with two printed circuits pressed against the cell supports, and a battery management system that clips onto the assembly.

This system makes the battery easily repairable and reconditionable, in addition to being safer and more reliable.

Please note that all current batteries contain small lithium-ion cells welded together, in a pack that is difficult to dismantle. Gouach has revolutionized the sector and established itself as the leading brand in repairable solderless bicycle batteries.
