Hello all, Im new to model boating and new to the forum. Reason for joining is that ive just bought my son a Black Stealth Rc speedboat and at the moment im happy with it as my son is only 6,the only thing is the battery last's up to half an hour and i was hoping for some information on buying a better battery that will last maybe an hour or longer and maybe even give it abit more power without burning out the current motors.Here is the boat its self an some info

http://www.gadgets4you.co.uk/Product/Radio-Control/Boats/Black-Stealth-RC-Speed-Boat/p-3044.html

the current battery is 7.2v with 1800mah,what battery could i get to make use longer an maybe even it slightly faster? Eventually when i have more knowledge in model boats id like to make my own mods an maybe change the motors but for now the simple ways i think i will stick with.Thanks any help would be great! Richie

Richie. Welcome to the forum and all that. Starting on a new carrer as professional occaisional model boat enthusiast.. how exciting !!

BUT. battery, you should be able to purchase a battery in the same type as the one you have, of at least twice the capacity, if not more. Have a surf for "the Component shop" . They are bound to have what you want or will make you one. Chances are you have a very common configuration pack.. As for faster, these things are normally optimised for the gear fitted, and more performance can only be had by expense and fiddling about. best buy something else once this one is mastered.

Having now just looked at the boat, this is a common sort, one of its problems is the motor control of all or nothing for turns (no rudder unless I am mistaken) and so there will not be much you can do..so advice as above. To be honest this is probably much too fast for a 6 year old as it is.

From your link –

"The huge capacity 7.2V Ni-Mh rechargeable battery will give up to 10 minutes of wave shattering fun on a four hour charge and allows plenty of time for racing, and cruising."

– the 30 minutes run sounds OK.

Higher capacity batteries of the same voltage will give longer run times. Provided that they are the same size and shape and the same connectors, they will probably weigh more and thus reduce speed a little. Not knowing either the internal layout or what actual electronics are fitted, I cannot comment on fitting a higher voltage battery, other than to say that if there was room for such, and IF the electronics and motors would stand up to it, that is the simplest way to get more performance. It is also the fastest way to potentially let the magic smoke out of the works.

A major refit of this kind of boat is rarely a good idea, since there is usually more work and cost involved that starting fresh. Best to enjoy this until you feel its time for something better, by which time you may have decided what "better" actually is.

Thanks Ashley for the reply, I have just bought a 4200ah 7.2v battery going see how that goes compared to the 1800, an yes looking forward to getting my teeth into some real model boat building eventually. hopefully being joiner by trade will come in handy somewhere down the line.cheers again

thanks malcolm, i have taken photos of the internal layout unfortunatly it is on my phone which was dropped last night so i could not upload with original thread, but by the sound of it i am under estimating the work that needs to be done basically because i have no idea about boating,power,motors,weights an everythin else to do with model boats lol, hopefully with the help of the internet and meeting people round the boating lakes ill soon pick up the know how. cheers

Richie. How about filling in you profile and letting us know a bit about you?

Agree with Malcolm. On a boat like this it will not be cost effective to re-fit.

The battery you have will not reach full capacity unril it has been cycled a few times (used), It may also be an idea to get a decent charger for it, something that charges at 300 or 600 mA say.. likely the charger supplied with the boat is a fast charger and that is not good for battery life. Component shop sells some nice little plug`n`play NiMh chargers at very reasonable prices.

We took the boat out for its first full run at the weekend an its alot bloody quicker than i expected for the price i paid,an if im honest its probably too quick for a 6 year old. I spent more time worrying about him crashing into other people's boats and the walls that i didnt really get much time to watch him enjoying it. The battery lasted more or less 30 mins and when my other battery turns up with its larger capacity it should be perfect for what we want out of it. I had a good go at its fastest an must say i had loads of fun an alot of people looking at it because of how fast it was.
