I am building an electric scooter, which is powered by 4 6volt, 4.5amp rechargeable lead acid DC batteries (http://www.jaycar.com.au/productView.asp?ID=SB2496
), wired in series to produce 24volts (18amps). I am planning to use an inbuilt charging circuit, which plugs into mains power (240v AC) and charges the batteries with 24v DC. It would also be helpful if an LED turned on when the batteries were fully charged. However, I am unsure of the appropriate circuit for this. Could someone please post a circuit diagram for this, or email it to me ([email protected]
), or direct me to a site which can help.
Any assistance is much appreciated!
