I'm at work and far from my tiny solar "house". I remenber I decided to to set Victron at max LTO value + a little, perhaps one or two volts more, this because I saw I was not at maximum value. Because the BMS should stop the charge too... The small converter accept maximum (theorical) value...

Here is the link (45Ah cells) https://www.alibaba.com/product-detail/LTO-Battery-for-30ah-35ah-40ah_1600082474647.html?spm=a2700.shop_pl.41413.23.214d3ff1PNrrgQ Before connecting them I have verified voltages (to avoid too different levels when I connected them in parallel) and didn't find...

And the provider answered this: "this problem is caused by poor battery cell voltage consistency . you need to make a good cell voltage consistency . take high voltage cell to discharge , take low voltage cell to charge "

Hi all I build a "24V" LTO battery using 12X4 cells, 45Ah each) I added a (bluetooth) BMS ( from https://fr.aliexpress.com/item/32997552090.html?spm=a2g0s.9042311.0.0.68b86c37BAbu8z ) Here a picture : I did this about two months ago. Here settings: When I read cells values from phone...
