Cells and Batteries

[Mike DavidsonParticipant @mikedavidson22772]

There seems to be a little confusion over the terms cells and batteries.

A Cell is a single unit wot delivers electricity,

A  Battery is a bunch of cells coupled together to give more Amps or Volts than a single cell would

Mostly, we modellers use Nickel Cadmium (Ni-Cad)’s or Nickel Metal-Hydride (NI_Mh) Cells in batteries of five or six cells. note the use of the word battery. as each cell delivers 1. 2 Volts, five cells coupled in series (i.e end to end) would give us six volts and the car racing packs have six cells in series giving 7.2 volts which makes the motor go very fast and hot too. it is possible to connect one or more cells in parallel, but there is a danger of charging one cell up the wrong way round which would make it die very quickly so don’t do it. buy a battery that fits with the highest ampere/hour rating you can afford. it will last longer in all senses.Another factor you should take on board is weight. you should take into account the weight of your power source before fitting it into your boat, otherways,the boat might sit deeper in the water than you might like, and might even lift the stern so high that your propellors are clear of the water Always read the safety instructions, and err on the side of safety. You can always build another model even if that one is a heap of charcoal at the bottom of the pond. So, enjoy your boating safely  Mike  D
