I offer this bag for use with the Grin Technologies LiGo battery packs -- but you can use it for other stuff, too.
Topeak Mondopack XL Seatpost Bag with quickclip rather than velcro straps for holding it from the seat rails. This allows you to quickly remove and reattach the battery pack from the saddle. Fits 4 LiGo batteries in the standard form, and up to 6 LiGo's by opening the expansion zipper. https://www.topeak.com/global/en/products/saddle-bags/382-mondopack-xl
