Now it so far with me. One of my three 120s Effekta lead flow battery has a much smaller capacity than the other two.
My morning route of 48 km is no longer possible. The voltage of the defective batteries is more than 1V below that of the other two.
A conversation with the supplier of Mr. Strubel Starmotec showed that there is this problem more often and therefore Starmotec soon plans to offer the BACS Analysis System to prevent this. This
have not run the battery charging with 36V part I have always finished loading with single-loaders to a final voltage of 14.7 volts.
All the more confused I am now once explained to me that Mr. Strubel single store because of the different resistances and the battery charger tolerances is harmful to the battery.
After reading the Manual BACS I am of the opinion that the BACS system when charging batteries does nothing else like three set to 14.7 V single-shot, or in the forum discussed PowerCheq battery equalizer.
It will be ensured that all the batteries fully charged uniformly.
The only advantage I see right now what is to be warned that at discharge if a battery is covered by the discharge.
This can also reach with three individual battery voltage indicators.
At discharge currents of 35-60A, neither the PowerCheq can provide with 2A or 3A modules with the BACS C4 bypass for the harmonization of the batteries during discharge, and always have identical charge.
What frightens me the report by Frank Blettenberg in which he states that a discharge lasting more than 60% damage the batteries. The 120s
Effekta batteries have a capacity of 70Ah (C1). It found that if you damage the battery if you have more than 42Ah takes an hour!
