Hi, reikiman (David)
I am using 4 BB EB50-12 Batteries for a motorcycle, KLR650, conversion I am
working on. The BB data sheet says:
50Ah @ 20 hour rate F.V.(1.75V/cell)
I am a little confused because I have read (Table 7.2-1) in THE ZERO-CARBON
CAR, by William H. Kemp (2007), on page 281 that 100% depth of discharge is
equal to 1.75 volts/cell per the table. Mr. Kemp is using(ed) Optima AGM.
I tried to get the sales guy in Cal with BB to discuss Depth of Discharge
before I bought the batteries, currently setting on the shop floor, and
could not get a straight answer, understandable but frustrating. I know
voltage is fluid and they, BB, don't want to get "caught" with their pants
down on that issue (warranty). But, I do need to understand where 80% is so I don't
create problems with battery life and the response from BB did not satisfy me.
My plan is to install a WESTBERG item no: 2DC10-76(COMBOMETER #2..Volts, 0-50VDC
..Current, 0-250ADC with a 250A=50mV Shunt. I would monitor system voltage and
decide when to call it a day at 80% depth of discharge more or less based upon
?.?? volts per cell time 24 cells.
