How We Tested the Balmar SG200

[@WTF-x-1000]

Great info, thanks Rod. I read your article "Making Your Battery Monitor More Accurate" and finally came to understand why other monitors can't show the actual capacity of a battery. Now I am using the SG200 on my RV.

I have been researching marine electrical and redesigning my sailboat's electrical system for 9 months. I only wish I found Rod Collins and ComapssMarine sooner. This is this most comprehensive source of information that I have found.

Maine boaters are lucky to have you handy! The rest of us too through your website which is a real treasure of information.

Really impressed as well, with Rod's knowledge and drive, that is

Hey Rod! Will you do some more videos anytime? I think they're very informative. Love your website as well.

Have a link to the studs you are using in the epoch lithium battery video

THE MAIN reason ALL battery monitors have inaccurate SOC is due to the resolution rate of their shunt and internal algorithms. If the shunt is rated for say 200 or 350 or 500 amps at +/- 1%, you get 2 or 3.5 or 5 amp approximations and variances. Also, many battery monitor gauges only read >1A charge or discharge -- meaning all those little trickle currents in (eg, from solar) or out (low current standby devices) add up over 24 hours to cause large discrepencies.

How accurate were the SG200 SOC and SOH readings when testing a LiFeP04 battery?
