What not to do with NiCad batteries?
NiCad batteries are fairly indestructible, but they will be irreparable damaged by reverse charging (i.e. being connected to the supply the wrong way round). Therefore, be very careful when wiring up because one mistake will loose you the set of batteries. Reverse charging can happen in another way. If you allow the batteries to completely discharge and then continue to draw current from them, not all the batteries will go flat at exactly the same time. The batteries with some charge left in them will then start to charge the completely flat batteries, resulting in reverse charging. When the model stops due to low power in the batteries, the batteries are not completely flat, but will continue to discharge if you leave the model switched on. As a result, if the model stops due to the battery discharging, switch it off to avoid and change of damaging the batteries. Also, avoid leaving the model switched on for extended periods (overnight, for example), in case the same thing happens. Re
