i2s Isolator powered by LifePo4 18650 batteries


Recommended Posts

Hello, I am new to the forum and new to raspi but do know just a little linux, and have just bought the i2s Isolator and Boss (in transit, not yet received).  Can someone please shed some light about the LifePo4 18650 batteries required for the i2s Isolator. I have read elsewhere; there are different types of these batteries i.e. "Use of a unprotected rechargeable LiFePO4 where a protected cell is expected is very dangerous".


My questions are:
1. Does the LifePo4 batteries get charged from the raspi, or would you need to manually recharge them, or are these batteries non rechargeable

2. do I need to be concerned about "protected" and "unprotected" LifePo4 batteries for the i2c Isolator
2. Allo recommends the battery option for the i2s Isolator but would a "Dual LLC PSU" be "as good" or "not so good"

3. what would be the best overall power arrangements for the raspi + Isolator + BOSS i.e would I power the raspi via usb and power the BOSS via the i2c Isolator batteries

 

All help will be very much appreciated

Thank you in advance
