I require some sort of a power supply!
 

Hi guys,

I'm a bit lost at the moment, i run electric 1/8 buggys, and run 4s batterys. To charge those battery's i normally connect my CHARGER to my dad's or friends CAR BATTERY.

Problem is,my dad drops me off to races now,meaning i don't have a car battery. What can i do?

If i buy a car battery,i'll have to charge that somehow,and it weights about 12 tonnes!

What are the other options?

Thanks.

if you have sockets available, just get a psu (power supply unit).
hobby king have them from about $25, you'll probably need something with a bit more grunt to charge 4s.
if there are no sockets, it's generator or car battery

This is the problem,

how do i charge a CAR BATTERY? i've got one at the moment but no idea what to do! and its bloodly heavy.

What does this power supply actually do?

i just connect my charger straight to the car battery then connect my lipo to the charger,

Thanks for the link by the way.

Charge the car battery at home mate, they're on eBay for about £20

Do i need a specialized car battery charger?

Has your charger got the capability to charge `PB` batteries as that is the posh term for car battery. So when at home plug your charger into your home power supply and then charge up the car battery from your charger like you would a lipo( select the correct charge procedure first). Thats how i do it anyways and have had no problems.

I have a power supply for sale matey, pm me for more details

Thanks for the help so far guys,hpi willl pm you in a second.

Would a 12v Sealed Lead Acid Battery (For Starter boxs) work ?

Its smaller and lighter than a car battery.

I'll only be charging my battery twice or 3 times MAX during the race,

Its a 14.8volt 5000mah lipo battery (that i'll be charging)

Thanks.

Nas, you only need a power supply if you're using 240v supply and your charger is 12v only. If your charger does both then no psu needed.
I may well be teaching you to suck eggs... but 240v is mains power and 12v is car power.

Use these http://www.ebay.co.uk/sch/i.html?_tr...at=0&_from=R40 to charge your 12v car battery at home

Depends on the capacity of the (smaller) battery. I'd suspect that it'll be up to the task. 5000mAh isn't actually very much. Most car batteries are in the 50-80Ah sort of range.

And rather than hammering your ordinary 12v RC car charger, filling a huge (relatively) car battery, just get a trickle charger for it from Halfords or something, last one i bought (a long time ago) was about 15 quid. Lasted me 10 years. Then i kicked it down the stairs by mistake.

This depends on how big your new sealed lead acid battery is of course!!
