Edd — the EchoCharge is a one-way device; it will only pass charge current from the House bank to the Start battery, not the other way around. Best practice suggests sending ALL your charge sources to the larger House bank, then siphoning some of that off for the minimal charging requirements of the Start battery. It really does work well.
