Charger circuit Answered
I'm planning to build a portable stereo speaker box thingy (you know what I mean). In order to power the 2x10W amplifier I want to use a 7.2V 1400mAh battery pack from an old RC car.
As the housing of the box will be sealed I want to implement a mechanism to charge the pack.
For this I wanted to achieve 3 things:
-If the Power-Switch is turned on, the amp should be powered from the power line
-If the Charge-Switch is turned on, the battery pack should be charged
-If both of the switches are turned on, the amp should receive power from the power line while the battery pack is being charged.
I have thought of the following cabling (see attached picture for a schematic)
The blue box is the amplifier, the green box the battery pack and the orange connectors are tamiya connectors (the ones for RC cars)
The first switch (marked in green) is a normal DPST switch which establishes the connection with the power line as well as the connection with the battery
The second switch is a SPDT switch and activates either the connection between the battery and the amp or the connection between the power line and the battery.
Will this work the way I think it will or does this configuration any faults? If the latter, what can I do I have to change?
I'm actually really new to electronics, this if my first project so forgive me, if this setup is actually BS
Cheers and sorry for the long post ^^'
