These do work well (albeit slow) as a buffer of additional storage.

They consume approximately 960k eu to fully charge a stack of water cells, which converts to 864k of output when depleted back.

Energy crystals and lapotron crystals hold better and more efficiently, but this allows for more unattended buffers near your MFE/MFSU.
