I purchased the Protek 3s 11.1v lipo pack for my TX.

The problem is, I have no clue what type of plug this is, and I'm getting back into RC and am in the dark (we didn't even do lipo when I last raced).

I have the Checkpoint balancer, but it also looks like the Great Planes one is identical.

I have one of the 3S adapters, but it doesn't fit the Protek plug (Portek plug is taller). Any hints on where to get an adapter or what type of plug it is? I called a-main, but gave up after waiting on hold for quite an extended period...

I have the 3S 3300 Protek made for my 3PK and the balance plug on it is a JST-XH or whats also called the Align style plug. Not sure thats what you need, but would be my guess that it would be the same.

Looking up JST-XH, that absolutely looks like the right plug, thanks. I see a few adapters online, so I'll see if I can grab one locally now as well since I know what the connector name is.

Thanks.

If anyone else runs into this issue, here's a quick fix. The Great Planes balancer that is close to the Checkpoint actually comes with the correct adapters for this plug! So a quick fix is to buy the adapaters for the great planes models, which work with the checkpoint as well.

Cool - supposedly Hyperion makes both of those balancers, so its not a total surprise that they interchange.
