Sets of Battery Clips to join PP3s as 72V/90V HT batteries.

[Yorkie]

These clips look handy for making HT batteries (e.g.90 volts) from pp3 batteries without any wires to make a H.T. battery for valve portable radios. A set of eight are required for 72 volts, 10 for 90 volts etc. They look neatly made and save a lot of faffing with soldering PP3 connectors together, or bridging battery connections with short lengths of tinned copper wire soldered to the terminals:

... A set of eight are required for 72 volts, 10 for 90 volts etc.

As his picture shows, you only need two! If you were going to provide individual connectors for each battery, you would still need to solder on wire links.

The conventional  pre-wired type, which you've probably already kicking around anyway, will do the trick. The wires on one will be needed to connect to the external connector terminals anyway and the other is easily modified either by shorting the wires together or, much neater, stripping the plastic cover and wires off and adding a shorting link.

If you can't find any, Farnell will sell you enough for five 90V batteries for only £2.23! (Plus VAT but free postage)
