The A450 is an economical, yet high-quality, 100-240V AC balance charger, designed for charging LiPo, LiFe and LiHV batteries from 2-4 cells in balance mode with a built-in automatic balancing module. For those using other battery chemistries, the unit can also charge 6-8S NiMH batteries with ease.

Despite its small size, the A450 packs a considerable circuit power of 50W and maximum charge current up to 4A. The user can easily select the desired amplitude (1 amp, 2amp, 2amp and 4 amp) using a sliding switch and the battery type selection is made with easy-to-use push buttons. Once you’ve configured the charger to the desired settings, red, yellow and green LEDs inform you that you have entered the correct program.

To prevent damage to the battery or charger, the A450 features short circuit and reverse polarity protection to instantly end the charging process if a problem is detected.

Included with the A450 charger are a power cable, mini Tamiya plug cable, T-Plug cable, and instructional manual.

In general, you should charge your battery with a charger output that is somewhere between 1C-2C (x1-x2) the amperage of your battery.

If you have an 800mAh battery, the 1A setting is recommended. If you have a 1300Mah battery, the 1A or 2A setting is recommended.

Once again, generally speaking, it is best to charge at a lower C rating than a higher one if charge time is not an issue for you.

Portable and easy to operate

Automatic balance charging

How To:

Set the charging output to the desired setting. We recommend 1A for any battery with a capacity lower than 2000mAh. Setting the output to a higher setting will charge the battery quicker, but the charge will not last as long.

Use the 'BATT TYPE' button to choose the correct battery type before connecting the battery to the charger. The LED will flash green & red.

NiMh battery - Connect the NiMh battery to the charger with the included Deans/Tamiya connector.

Lithium Battery (LiPo, LiFe, LiHv) - Connect the battery to the charger with the included Deans/Tamiya connector. Insert the balance cable into the correct port on the side of the charger (7.4v, 11.1v, 14.8v).

If the battery is connected properly and has been set to the correct battery type, the LED indicator will change to indicate the current battery status, see below.

For NiMh batteries, hold the 'BATT TYPE' button for 2 seconds to begin charging.

Explanation of LED Status:

Green & Red Blinking LED - Charger is ready to charge

Solid Red LED - Battery Capacity is less the than 25% charged.

Blinking Red LED - Battery Capacity is between 25% to 50% charged.

Blinking Yellow LED - Battery Capacity is between 50% to 75% charged.

Blinking Green LED - Battery Capacity is between 75% to 100% charged.

Solid Green LED - Fully charged.
