I use the Orion version of the checkpoint balancer...http://www.teamorion-avionics.com/Ce...lancing+System

basically the same thing. You don't need to match brands but if you do go with the checkpoint or orion balancer, or any other brand, you can use these instructions to fit to the orion lipo packs...http://www.teamorion.com/orion/faq/harness.gif

However, if you are using orion packs you might not use the balancer much. I've only used my once on each pack I have just to to be double sure my voltmeter was working. The pack was so balanced I couldn't even start my ICE in time before the balancer shut off.
