The Pickle BMS is similar to the ZBMS in that it is a charge-only BMS. The Pickle BMS comes in two different versions: the 15s and 18s drop-in replacements for the Pint/XR and GT respectively, and the 18-20s version, made for aftermarket battery packs.

The 18-20s can be purchased here: https://pickleworks.ca/products/18-20s-picklebms

The 15s and 18s is still in development!
