Hi chaps, what would be the best battery to use with a Quicrum 1060 brushed speed controller. In the little booklet it states you can use 3.38 lipo or 5-8 NiMH battery. I have no idea which is best, I am looking for a long running battery for a submarine. Thanks for your help

Input: 2-3S LiPo/6-9 Cells NiMH

• The question is what space do you have? and how much weight can it cope with.

I have around 8 inches by 4 by 4. I can trim for weight

That's quite a space    so the next consideration is budget? and the voltage range of the motor.

Just for future information these E S C will work with gell cell batteries.  I have a Robbe sea wolf submarine powered with 3 cyclone cells using this type OF E S C works fine

For the same weight/volume you get longer runs off Lithium.  But if you want to be sure that you can recover from mistreating the battery, NiMh.  In both cases, within what weight can be carried, as big an A/H figure as possible at whatever voltage you decide on.
Lithium gives lots and lots of Watts per kilo and will give enormous current for any given capacity (look up "C" ratings).
NiMH gives rather less stored energy per kilo, and not as much peak current handling.
SLA gives not much wattage per kilo, and a very low C  rating.  SLA "can" deliver enough current to start a car engine, but not for more than a few seconds.  They can not sustain a high current without shortening their life expectancy a lot.  They were tolerated rather than greeted because back in the day they were the only game in town.  Best for low current and where there is a need for ballast.  They also need good ventilation when charging - they have been blamed for the occasional exploding sub.
