Can i charge an a4 with an lcd charger?

Short and simple, can I? This will decide whether or not I pick up an a4.

Seem like yes.

Since replacement chargers are no longer available anymore, a lot of people have been asking for the specs on the stock charger so they can try to find suitable replacements. I took a multi-meter to my stock Angel LCD charger and my stock A4 charger to get the output specs.

NOTE: The charger from the LCD is identical to the charger for the IR3 and they can be used interchangeably. The charger for the A4 and up is universally interchangeable and can be used to charge all of the Angel batteries except for the LED, including the older 6 volt LCD and IR3 batteries.

Both chargers were plugged into a 12v cigarette lighter to wall-outlet adapter. Results:

LCD Charger:

Input from wall adapter: 16.96 volts

Output from charger: 15.96 volts, 1.41 amps

A4/Flex Charger:

Input from wall adapter: 16.96 volts

Output from charger: 14.95 volts, .632 amps (632 milliamps)

The barrel connector on the charger is a 3.5mm outside diameter size H coaxial DC power plug. The outside sleeve is positive, the inside sleeve is ground (note that this is backwards from most common configurations).

Conclusion:

A NiMH charger rated for a battery voltage range of at least 4.8 volts; with an actual output of 12 volts and at least 600 milliamps; with a 3.5mm OD size H coaxial DC power plug connector; and with positive on the outside sleeve and ground on the inside sleeve should be suitable for charging any Angel battery except the LED (LCD/IR3/Speed/A4/A4 Fly/G7/G7 Fly). You can commonly find these types of battery chargers at RC shops and hobby shops. It's important to make sure that any charger you buy is designed for NiMH batteries. The Angel circuit board has a cut-off circuit for charging, so it is technically possible to use a "dumb" charger or a plain DC adapter. However, it is a good idea to use a "smart" charger with its own cut-off circuitry rated for at least 4.8 volts so that it will not over-charge or damage your battery.

Yup.. 3PEED and A4 are both basically an IR3 with tweaks, they all use the LCD style charger.
