Hello,
I am looking at cells with a maximum charge voltage of 4.15V. My charger maximum output voltage means this is not exceeded as i can only achieve 4V per cell average.
However, i appreciate theres a good chance some cells will deviate hence the need for balancing/protection.
I dont have budget just now for fancy BMS like Batrium, but a 14S 60A "scooter" BMS like ebay item 323926226256 would provide essential safety.
The issue i have is most of these types of BMS balance at higher than 4.15V, eg the one linked is 4.18V balance and over voltage protection at 4.25V.
2 questions...
1. Is it generally required protection and balancing voltages should be less than the cell listed maximum charge voltage?
2. What BMS options are there which may permit adjustment of these settings in the sub 100 price range.
Cells are EIG eplb-c020 and i am looking at 14S5P for 48V 100Ah configuration in a low power (20-40A) home energy store.
