Hi like most or you Im struggling to find a use for cells which dont make the minimum standard for inclusion in my powerwall. In my case thats 1800mAh.
Im left with over one thousand cells between 1400 and 1800mAh It struck me that they could easily be put to service in a reserve battery for use in a power cut or other outage adding about 6kwh of power per 1000 cells to the system in such a case. They would not be cycled daily like the main bank but left on standby for such an event.
No need for a bms or anything other than some switch gear to manage the changeover etc.
We have in the past year had to hire a jenny three times due to weather events.These cells are just sitting there in boxes looking a bit sad for themselves.
Very interested to hear thoughts of other users on this.
