Because these boards are often found in devices out of warranty, they have become a favorite for DIY electronics enthusiasts. Hobbyists often bypass faulty sections of the V1.3 board by integrating external or standalone boost converters to restore charging functionality. However, because this board handles the massive current required for jump-starting (often 400A to 800A peak), any structural modifications to the primary power rails must be handled with extreme caution to avoid thermal runaway.

While v1.3 is a superior version, it is not without faults. Users upgrading from v1.1 or v1.2 should note the following potential friction points:
