The four 100aH Battle Born batteries in the system were charged to 100% by 4 pm. Thirty minutes for ~10% capacity. (The math is easy to extrapolate from there assuming a linear curve.)
My question is about the charging characteristics of the Battle Born batteries. Is the charging actually linear? I ask because when I charge my lead-acid Trojan batteries, it takes much longer to charge the last 10% than earlier in the cycle. For example, I charged my batteries recently when they were at 50%, I could put in over 40 AHr running my generator an hour (about a 20% increase, to 70%). The amount of energy going into the batteries will decrease from there. I don't bother using the generator if the batteries won't accept at least 20 A. I wait for the sun to come back and let the solar panels complete the job. So will the Battle Born batteries accept "high" energy input right up to the point where they are full?
thanks,
Dave
