Hello guys for a present il be getting thw model slipway kit dutch courage. I have 2 mfa 540 with 2.5.1 gearboxes i believe on them and 2 mfa torpedo 800 i put these straight onto a 12v lead acid and was happier with how the 800 performed. Now would i be able to run 2 of these through a action p94 esc a mixer ok from a 12v battery. Next question is would i be able to get a big ah battery without any issues any advice apprdciated thanks chris.

Fastfaz:
   Mixer will be fine and Component shop will have a large AH SLA battery (various sizes all are listed on their website). I used a 14AH SLA battery in my Maltby it was quite large, the size you can get in the hull will dictate the AH size so measure it up then look on Component shop web site to see which battery you need . You can always mount the battery on its side. Hope this helps.
     Regards, Pete. :-))

Not all radios, and, importantly, the things that plug into them, respond well to 6 volts.  Action are notable there.  A better option is to use a UBEC to provide a stabilized 5 volts for the control components.  Just use ballast if it needs it, less chance of forgetting to charge up a passive piece of weight as opposed to a vital battery which will probably not be sited where it is easy to get at. 
Many ESCs have a BEC built in, which usually removes the need for a separate battery or a discrete UBEC.
