Whats the best bullet plug that fits the checkpoint/orion lipos & is easy to solder........thanks

The Castle bullet plugs. Just wished they were offered in separate male/female plugs.Have too many female plugs.

Actually, now that I think about it. The Castle bullet plugs fit snug on my SMC batteries, but on my Orions, they slip out easier. Banana style bullets work better on the Orions.

I've been using the banana style with my hard cased IPs. They're easy to solder - just be sure to melt solder into the bullets and tin the wire. Then all you have to do is stick wire in bullet, apply heat, makes sure everything got melted and pull heat away and let cool.
