For those lucky enough to own a Sinclair C5, you will probably be aware of the issues with connecting a car or leisure battery to the C5.
While it is possible to use the type 038 batteries with some pole adapters in a C5 in conjunction with the original battery cover or key switch, these batteries have very small capacities (typically about 37 Ah). What we want to use are the larger leisure batteries, which last much longer and are better suited to powering the C5.
With this design, we can feed a strap through the unit, which allows it to be placed on the battery without it moving around. The 2 brass contacts come from an old UK plug cut to size with some 79 amp-rated cable running from the contacts to the battery, which we attach with some quick-release clamps.
The key switch can then be clipped onto the adapter in the same way as it would connect to the old battery cover.
For those with the original Sinclair C5 battery charger, that too can be used:
