When I was a child I had 2 model boats which used an oblong pack of 6 not-quite C sized NiCad cells, 7.2 volts, and about 1200mA or so.
I have dug them out with a view to entertaining the nephews. The NiCads went years ago.
One boat has a 540 sized motor (just a "normal" one, not a more powerful competition tuned one), and the other has a "normal" 380 sized motor.
As they are boats, and space isn't at a premium, is there any reason not to:
- Use common C sized NiMH cells in their place?
- Use common AA sized NiMH cells?
Both would offer an increase in capacity, and in the case of the AA cells, are cheaply available from IKEA.
Thanks in advance.
