    LiFePo4 Cells — how do you Really know what you’re Getting ??

    Thanks — I checked her thread and the link she has still goes to an AliBaba page ... that seemed confusing ... many different listings and pricing’s all appearing to use the same video advertisement showing all kinds of cells ??? She says pick-up in Houston ( where I actually live ) so maybe if...

    LiFePo4 Cells — how do you Really know what you’re Getting ??

    Thanks for the thoughts ... So - if you can only buy ‘real’ cells from a manufacturer, and since they’re all in China - how does one go about Doing this if Not on AliBaba ?? OR - does anyone have another ‘reliable’ source for actual “New A+” cells ??

    LiFePo4 Cells — how do you Really know what you’re Getting ??

    Seems like All sellers of LiFePo4 cells claim “A+ New” ... or claim nothing at all ?? So are you Really getting “New” cells and are they Really “A+” and how do you Know when you buy ?? If someone advertised “B- Really CRAPPY Cells” then I probably wouldn’t buy those !! ? But nobody says that...

    How to ‘top balance’ with only a 12v charger ?

    Ok - Thanks .... that’s starting to make some sense. So I really shouldn’t use my shore power charger At All ?! And going from 13.6 to 14.6 at 0.1v per day could take weeks ( with cloudy days ) ... but patience is a virtue, especially when you don’t have the $$ to buy extra chargers for a one...

    How to ‘top balance’ with only a 12v charger ?

    So now I am SO confused !!!! If the BMS will ‘balance’ the cells what is all this ‘top balance’ stuff that everyone seems to make so important ??? If I do the method of “bump up by 0.1v” on the solar charge controller what ‘final’ setting an I headed to ?? Also, word I read says NOT to ‘float’ a...

    Once “in service” the battery will be charged by the solar charge controller (12v and not ‘adjustable’ output except for charge settings) and the 12v shore power charger when plugged in.

    How to ‘top balance’ with only a 12v charger ?

    The title says it all I think ?! Without a charger that does 3.65v how can you ‘properly’ top balance new LiPo4 cells with only a regular 12v charger ?? Thanks.
