More water to bats

Haha today put more water to batterys, it took abit over 10liters  to fill em from min to max 🙂

It seems need maintanence at least once a year, now they are on low use, they consume alot water, on float voltages 🙂

If anyone has technical specs what is factory float voltage for this kind water flooded batterys please comment, i have keep em 13,4V and boosted width solar panel to 13,9. Once a week also charger automatic bring them up up to 14,4V (programmed)
