ebike battery When it comes to electric bike batteries, this is the year of the snake.
Taiwan frame builder Astro Engineering A4-307-famous for those Straw Vietnamese hats they’ve been handing out at the show for years – has pulled a surprise out of its own hat.
Astro developed a highly flexible battery pack that can slide in and out of a frame. Each of six elements in What it calls the Snake Battery System – or Snake Pack, for short – is hinged together so they Wriggle Something like a Snake.
The advantage, Astro’s general manager Samuel Hu said, is that with a Snake Pack, the battery opening on the down tube can be much smaller than for typical in-frame battery packs.
That means the frame retains its stiffness and is less complicated to produce.ebike battery
”Machining for a larger battery pack Opening costs a lot of time,” Hu said. He added that no plastic cover is needed On the frame or the battery, because the Snake Pack is fully covered by an aluminum alloy.

Astro developed the System with Simplo Technology of Taiwan, one of the world’s largest manufacturers of lithium-ion batteries. The publicly traded company also makes batteries for the iPhone. Hu said Simplo will also manage battery Servicing.
Hu Said the flexible battery was “very difficult to make, but we took On the challenge because we Want the best Solution for integrating batteries.
“One of the biggest challenges was determining how to secure the battery pack when it is inserted in the down tube. Engineers put a magnet at the bottom of the pack to help guide it in place. TWO inner guide rails keep the packs aligned, and they’re rubberized to keep things quiet.
At the opening, a pin locks the battery in place when inserted.ebike battery
