Baguley query

[New Haven Neil]

Hi all

I have been asked to sort a battery supply out for a Baggy, my friend just wants a basic installation, but I have no idea how many volts I need to marshall into it? I can do speed controllers etc not a problemo.

Only looking for a scale 20mph or so flat out, anyone got any idea? 7.2v pack enough????? :thinking:

All thoughts greatfully received

Neil.

Probably. I have mine running on 14.4v and it goes dead fast if you let it, 7.2 will probably be fine. Connect a 7.2 battery to the wheels and have a look.

Depends on what running time you want, I tend to run with double that in my LGB locos

Ah, I should have said I don't have the model - I'm just providing the gubbins.....it's across the sea on your island!!

Running time depends on Ah capacity, not voltage, but speed depends on volts.

9.6V, 2300mAh

do'h......... :clown:

I meant an Accucraft Baguley, Palmerston!

my bad!!

Some recievers stipulate what V's are required eg. Cliff Barker min 12V

I used 14.4 volts of Nicads with RCS radio control and MyLocosound sound. Two years later, it still runs for 2.5 hours and pulls well.

I really didn't word my initial query very well, did I? :clown: Sorry guys, I know you are all trying to help me!

It's a manual installation he's after, not r/c. He only wants a slow speed, not a flyer! I can build a manual electronic speed controller no problem, I just need an idea of how many volts are likely to give the speed he wants flat out - I think his young (very) son is going to be the primary driver. Which is hard, when i don't have the engine!! :wits:

Understand now, in the Playmobil that my grandsons play with I use 9.6V that seems to give a reasonable gentle speed, but you might need 2 packs one in and one out charging. The little seeties when they start playing they don't want to stop!!

I think 16v would be plenty Neil, and also that you would get some loss of volts as a battery discharges, so when nearly flat you wouldn't get all this delivered. You might be OK with less to start with, but I'd go for overkill rather than under doing it. I'd presume a 16v pack with the controller turned maybe about half to two thirds on would last longer than an 8v pack running flat out? Happy steamings, John  

Edit: That said, allowing for a young driver to be "limited" then yes maybe just put 8 cells in?

Missed that post somehow, sorry James. I can't try it, it's across your side of the Irish sea!! I had a feeling 7.2v would be enough, for a slow run on a short end to end line, thanks.
