Yep, I've done it, completely lossless power transport, with unlimited range.
Mods: IC (obv), BC, RP, BC additional pipes
The first image is the charging station. Empty lapotrons come in through the right and are put into the top of the MFSU. The filter next to the MFSU has a full lapotron in it, so when it's done charging, it is pulled out and sent through the teleport pipe.
The second image is the de-charging station. The full lapos come in through the right tele pipe, and go into the chest. They are pulled out by the wooden pipe (assume an engine replaces the redstone power I'm using), and sent down to the MFSU. The redstone pipe activates a 100 second timer, which is enough for the crystal to de-charge completely. When the timer causes the wooden pipe on the left to pull out the empty lapotron (again we must assume that it turns on an engine for just a second), it is sent back to the chest, and the filter there with an empty lapotron in it pulls it out and it is sent back to the charging station. The obby pipe behind the MFSU is just to catch extras.
The more lapotrons in the system, the better it works.
Not having at least 512 eu's coming into the charging mfsu (preferably 600, though not in one packet!) will cause the system to bottleneck there, so don't try to use this for really small power amounts.
So there you have it, all you need to transport tons of energy from one point, to any other point!
