QUESTION: Will it damage the battery? No its a -Delta V pulse charger so it will automatically cut off when the battery pack is charged. It charges at 500mA then drops to a trickle charge so it will not get your battery hot through excessive input current. Its furthermore a "world wide voltage " so there is no trouble if you need it in any other country. It comes with large tamiya and large to i-Cybie connector.

If you are in the U.S or Canada, it will come with a U.S plug and if you are located in Europe it will come with a European plug. Any other country other than these stated, you may need an adaptor.
