Do it right, and get an appropriate balance charger. The IMax B6 is the benchmark for reliable airsoft lipo chargers. You don't "need" something that good to play, but think of it this way; it'll extend the life of your batteries, protect your airsoft investments, and later when you branch out into other guns or needing other batteries, you'll have what you need already. Lipos don't tend to burn or explode anymore, but the odd one still does.

There are adequate $30 lipo chargers out there. Make sure that your charger does an appropriate balance charge, and is reviewed as being reliable.

The airsoft community for the most part will recommend a charger like the IMax B6, due to collective experience. For safety and equipment care, a charger is one of the places you don't want to cheap out on.
