Alright, now I’m a bit confused and maybe this post will help others down the line so my question is about the capacity setting when setting up a BMV-712. The unit has a default of 200ah and the manual states this is at the 20hr rating.
Not all battery manufactures provide the specs with the same terminology or scale of rating, and on top of that there is often a Reserve Capacity (RC) which is often described as being @ a certain Amp load measure of scale, and sometimes that is provided as opposed to a Capacity.
My question is, what specification does the 712 need when setting it up?
At first I thought the I could use the RC value which my manufacturer rates in minutes @ a 25A load. But digging around I was finally able to find a Capacity spec, however the scale of measure is not provided. The manual states that the 712 wants a figure based on a 20 hour rating which makes me think not all manufactures use the same scale of measurement.
I imagine others will run across this issue and so I thought I would post this for clarity since run of the mill store bought batteries don’t always offer all the specs, yet some of the terminology is similar which can make things even more confusing.
For my application, which is using my bank to power brushless electric trolling motors, Reserve Capacity is the important spec I use when shopping for a battery because the motors draw heavy loads for a long period of time and they get used heavily in a single outing, whereas some may be more interested in small loads and how long that load can be drawn from battery before discharging it to a state that is unhealthy.
Thx.
