Some way to prevent sculk blocks from loosing their charge

I would like to see some way to stop sculk blocks from loosing their charge, it would make them a lot more useful. This could be as simple as applying power through redstone, or maybe something more complex that could involve the new Echo Shards (Perhaps you could place them, or craft a special sculk block that acts as a cage for the charge). Another possibility is that sculk blocks don't loose any charge at all unless the charge moves to a different block (or vice versa). I know the charge decay is there by design, but I think it would be a lot more interesting if there was some way to prevent it.
