lol.
Sometimes people here wish for new people to do some research on their own prior to giving them information. There are alot of "sticky" threads at the very top of each forum that address the most common answers that are asked.
Since you are a fellow WA resident, here is your answer.
Given that your parkzone lipo's use the JST-XH balance connector, you will find that a GREAT many different balance/chargers use this as a standard connector, or a standard supplied 'board' in cases where they use a dongle arrangement.
The Hobbypartz Thunder AC6 uses this dongle/board arrangement and comes supplied with an JST-XH balance board, so you are good to go.
As you purchase other lipo's that use different balance taps, such as thunderpower and hyperion, you will just need to purchase different boards, which usually range from $4 to 6 bucks depending on where you buy it.
Do yourself a favor, don't buy any more Parkzone batteries. You'd do far better to save the coin and buy other less expensive brands.
Also, ditch the EC3 connectors. Use a deans or perhaps the newer XT60 connectors. Those are great.
