if you are going to race as per the standard rules, then the only battery permissable is a 7.4v nimhs pack. If you are going to just mess around, then anything!

Servo, I use a small micro servo, to save weight! we are a very competitive bunch that race at St Helens Model Boat club! weight is the enemy with these boats :-))

Well they certainly park their 500 hundreds pretty well, at least Duracell does !! :} :}  Inter Club soon  :-))

Also no extra weight, trims etc if your racing

That's because these batteries contain 1.2 volt cells.     8)

Just had a thought  (dangerous yes I know)  When the 7.2 volt are charged they can go up to 8.4 volts    :}

Yes, it's a number followed by mAh   (milli amps per hour)

For example 1000mAH  is 1 amp for one hours running. You can see by this the amount of time you can expect the motor to run.

Hope this helps

You are still stuck with 6 cells, and the battery saying 7.2 volts on the label.  I don't recall anybody mentioning an A/H limit, but generally, for a given size, the higher the A/H, the heavier the battery.
