Title: Simpliphi LiFePo settings
Post by: Heterodox on November 07, 2022, 12:26:59 AM
What are the recommended settings on 3048DIY for Simpliphi 3.8 batteries? How can I take advantage of the 80%+ DOD on these batteries when the Battery
Discharge Limit Voltage can't be set lower than 40v? Thanks.

What does Smpliphi recommend ?
Okay I looked up their specs.

They say 48v is 100% discharged and should be the low battery cutoff.  So why would you want to go down to 40v ?
If you look at their graph they say under most loads that 80% discharge would be around 51.5 to 52v range.
And they say if you take battery down to 100% depth of discharge you only get 1/3 of the battery cycles of going to 80% /
