[RE-wrenches] speaking of batteries

[Maverick Brown]

In a battery backup mostly float state with low cycle count, I’d add to a bank several years later. 

It’s really hard to say “several” since most LiFePO4 batteries haven’t been alive for that long. 

I’ve personally added 8 Pytes E-Box to 8 eFlex with no issue. The Schneider Insight even allows two comm cables and shows both SOCs. 

At another customer, I’m adding four Pytes batteries a quarter until we get 16. Grid Tie battery back up. Once we get to 16 will turn on time of use metering and exercise the batteries a bit more.

Thank you,

Maverick
