Hi,In reading about LifePO4 and issues with directly connecting a stock alternator, I think I learned:
a) the alternator could burn up due to low resistance of battery resulting in extended high output from alternator
b) there are problems if the battery's bms disconnects the battery resulting in voltage spike from alternator that destroys it (and potentially sends this voltage spike to throughout the dc system).
Hopefully I have the general gist of those two points. Point 'b' got me thinking that the possibility of the bms disconnecting the battery exists whether it's an alternator doing the charging or a charger. Let's assume that there are no alternators in the picture and just a battery charger (my existing which I think can be programmed with a charging profile suitable for the LiFePO4). If the battery's bms were, for some reason, to disconnect the battery while charging, what affect would that have on the charger? Would it be 'bad' as in the case of the alternator described above, or would the charger gracefully handle this situation? Basically, I don't want to risk destruction of my charger/inverter by the whims of a bms.
Also, since a house bank may be comprised of multiple batteries with each batttery having it's own bms, I guess it's conceivable that just one battery's bms could disconnect, leaving the bank at a fraction of its nominal size. This seems less problematic, but wondering what effect this situation may have on the charger.
Wasn't going to go down the LiFePO4 path, but considering now because I can't believe the price of AGM's.
Thanks for any info.
