I agree that's probably the best way to go ATM, the ZCell is just too expensive, and the periodic maintenance pumping thing means you need at least 2 of them if relying solely on them off-grid, or more if you have high power loads.

The price is a shame. The maintenance wouldn't worry me as it was for a second battery pack. I am in the process of increasing my system capacity, and have been looking more closely at all the technologies that are available. In the end I still think the LiFePO4's are the go. For all the talk of being fragile, i've been unable to find actual real-world examples of systems that have had battery failures while correctly using a BMS.

On RenewEconomy today:
>>Australian battery storage developer Redflow has hit a speed hump on the road to commercialisation, after the discovery of a fault in its zinc-bromide flow batteries prompted the Brisbane-based company to suspend deliveries.
