Understanding Battery Voltage and SoC

By |2020-06-02T22:32:57+05:30April 21st, 2020|

The reason there’s not a simple relationship between battery voltage and state of charge is that your solar system is constantly doing different stuff – electricity is coming and going all the time.  However, there is a simple relationship between the two if the battery is disconnected from all chargers & loads and has [...]

50% Depth of Discharge for Lead Acid Battery

By |2020-06-02T22:42:51+05:30April 21st, 2020|

"Lead acid batteries should be discharged only by 50% to increase its life" - is an oft used phrase. This means that we should cycle them in the 100% to 50% window as shown below in the Typical state of charge window parameter. So it follows that the usable capacity of a lead acid [...]

Lithium Ion batteries are cheaper than Lead Acid.

By |2020-06-18T11:59:58+05:30April 15th, 2020|

Lithium Ion versus Lead Acid batteries In this blog, we will bust the myth that lead-acid batteries are cheaper than lithium ion batteries armed with data. Lithium ion is way cheaper than lead acid batteries and we're going to use battery studies and data sheets to substantiate the claim. We are going to talk [...]

Peukert’s Law and Lead Acid Batteries

By |2020-06-02T23:29:58+05:30April 1st, 2020|

Peukert’s Law and Lead Acid Batteries Note: This blog is for battery enthusiasts. To understand peukert's law and with an intermediate knowledge about batteries and terms like C-rate. Let's talk about the capacity of different solar batteries in real-world circumstances because battery manufacturers are advertising a capacity rating in Ah and a lot of [...]
