After 2 years of searching I finally found my battery charger for my 7.2V RC battery’s. They have not been used for nearly 3 years and I am surprised that one of them still works.

it’s a Shame I can not use the same referb system that I used on my Lion’s but I shall find out if the last battery still works tomorrow and run my 1/12 scale scoobie.

The only issue with it currently is the mechanical speed controller. 
The contacts have far to much play on it (and as evident from the sparks it lets off) its not very energy efficient.
