Please advise the digikey part no. for the 2 pins plug and socket for power connection on clock board.

These wouldnt drop below 3.45 till about 1/2 way through their charge, sits on 3.50->3.40 for ages and at ~90% discharge they are still sitting about 3.2. Mine wouldnt drop off that steeply under a 10A load.

they might be lifepo4, but probably not Nanophosphate. what are you using to cut off the voltage, till the battery board is ready that is? could you have damaged them with repeated deep discharge, or have they always been like that?

They are 2pin JST PH series, I believe, 455-1734-1-ND - I don't have the connector in hand or a clock board so I could be wrong, but if in doubt, check the BOM for the battery board, I think Ian would have used the same connectors there.

As I still testing my setup, haven't considered the cut off yet. The batteries are new and have been recharged less than 10 times. Only been deep discharged twice.

Waiting for Ian's battery board to safe my life again

Thanks hochopeper. Found them in Digikey.

I'd get Ian to confirm that, it's just an educated guess. I went and checked the BOM for the battery monitor board and it is a through hole version, so not the same as I had first thought.

Thanks hochopeper, for the P/N of SMD version,

455-1165-ND
455-1127-2-ND
455-1704-ND

I like the isolator board, it makes the grounding design much easier for a DAC to get rid of ground loop. The clock should always be treated as an analog part for a DAC. The isolator board makes them together.

I guess i'll take that bow now

lol

I want to know what bigpandahk has planned now he's the only guy apart from Ian with more than one of those isol boards!
