Starting this years activities I had to exchange the charging controller as the old one did not have protection against deep discharge. This led to a destroyed battery - so i had to exchange both - battery and controller...

The new controller now has a nice display and protection against deep charge. The voltage levels (float voltage, load off voltage, load on voltage) are adjustable. I'm missing some details during the charging activities (like consumed w/h, charging energy w/h) which i actually exepected the controller to have. As it looks it does not have these functions - on the other hand it was not a really expensive thing - something like 20€...
