18650 14.8v Li ion Battery Pack for Solar Panel

Shenzhen Sinoli Electronic Co.,Ltd | Updated: Oct 17, 2018

18650 14.8v Li ion Battery Pack for Solar Panel


solar panel battery nowadays are more using 18650 li ion battery, instead of lead acid AGM.


AGM battery for solar panel has many defectives in real ultilization. here is what SINOLI customer say, AGM Battery have some shortcomings: significant capacity drop during cold weather, Peukert law, or significant capacity drop when draining with high currents, they are bad for solar because they sufer from sulfation if not recharged up to 100% after drainging them, only around 700 cycles if discharged to more than 35%-40% DOD etc. All that is not that bad, but they cost marginally less than LifePo4 or other lithium chemistries, so they are not worth it.


here is not to discuss what defectiveness of lead acid AGM battery. while, at this time, li ion battery is the best choice to take the place of lead acid AGM in solar panel energy storage system. we discussed a lot of what's the advantages of li ion battery. more and more 14.8v li ion battery used in solar panel is to replace for lead acid battery. size will be more smaller, working platform will be much higher.
