200a/hr LFP Load test results…
I choose not to charge my 200a/h LFP from the alternator because (say, once fully charged…) I prefer not to have it maintained at say 100% SOC…I suppose a switch would remedy this, but as primarily a ...

Note that I only provided here the short version, this only after first validating that the Victron BMV-12 was near spot on in two separate test by using a steady, continuous 24.5 amp squirrel cage blower (inductive load) and another by using a 500w halogen shop lamp (resistive load) and data logging both per each hour to arrive at total ‘consumed’ amps…In the end, the BMV-12 was off by only a minuscule amount of no empirical concern - really, not at all what I was expecting - so I found it’s accuracy to be quite exceptional…
There’s even a longer story here that I won’t go into, however that first led me to question the meter - which turned out not to be the case!…This test result then led me down a different road (battery replaced under warranty - subsequently verified it’s replacement!)…But as I stated the meter proved to be highly accurate, especially considering the nuances related to tracking SOC (voltage, coulomb-counting and embedded look-up table - total consumed amps seems like the easiest) Some truly outstanding engineering in my view - Meter programming was strictly per Victron's own user manual….The 200a/hr replacement battery tested out at 215 amps…
