The end (U) went back to the trickle charging after sapping all the power from T. It's just going to fill up from A to U.
I removed the power stations from A and now G is taking from A. I assume it's going to work it's way down to U slowly block by block. It stopped after A was empty. Now, B-H are full, and the last block (U) is trickle charging from I. A is empty and oscillating +50, -50...
I cranked up the output to 50 on all of them which I should have done to start. The last one is now trickle charing 50 per tick. The first one is emptying itself into the next non-full one in the line. Not sure if I want to sit around and wait to see what happens when this fills up the end blocks.
Edit: (sorry, last one...)
After the last one filled up, the battery stabilized. No more movement. Then I realized, it's only filling at 25 EU (because of the splitting of the cables to both MFEs and only 25 being sent down the line. I hooked a furnace up to the U block and started smelting. It was taking form the U block and replenishing it from H (the closest non-full MFE.)
Given that you lose half of your EU throughput by the "automatic leveling" being done at the beginning of the line I'd say it's a terrible design and should probably go with the designs Leonon is using unless density is your only concern ... or you can make two parallel runs that both run through one MFE to get your final 50.
