Bert's 510 passthrough suggestion is right on. That's what I'm using as I type this, a 510 passthrough with a Volcano atty. The Volcano attys have a little bit taller bridge (the part that sticks out) and work a little better, but they do drain a cart a little faster.
I use both a Volcano (L88B, just like your Blu) and a Magma (510). Other than the chargers, all parts are mix and match. With the batteries, the big difference is the Magma(510) batteries last almost twice as long as the L88B batteries. The plus for the Blu/Volcano is a bit better flavor.
