Hello everyone, I have 3 batteries in parallel from 110 ampere 12v c100 for a total of 330 ampere.
For my personal technical increase, I had to ask for some information.
I know that lead-acid batteries, compared to lifepo4s, are very different both in type and performance.
Having 330 amps, I report some performance detected at sight with the regular software regarding the variation of the voltage under load.
The batteries have a constant load of about 43 watts for 24 hours and do not make a turn on performance or anything else.
Carrying out tests, then charging more watts of absorption up to a certain power example: absorption 90 oscillating up to 130 watts including the percentage of consumption of the inverter both at rest and in power delivery, the voltage of the batteries drops slightly, that is, if with 43 watts I have 12.50 with the load described above, it oscillates until it reaches 12.25 +- 12.30. This test load that I carried out for as many as 8 consumed and then dropped the voltage to about 12.05 volts (about 50%). As soon as everything is disconnected, the tension suddenly goes back to 12.35 + '12.40, making me understand the real consumption.
The question is: how much can an accumulation be pushed so as not to stress it? The supplier had told me that for this type of batteries I could also charge 3 amps (negligible figure considering the batteries and their capacity), perhaps because of their characteristic of being c100? How normal can a drop in voltage under absorption be considered normal?
