As part of the Silver pack , our review Wonder Roo Pearl was fitted with a 110L grey water tank behind the axle set , while two 95L fresh water tanks were fitted towards the front . When full , these tanks will contribute to the ball loading ; however , considering the unladen ball mass is not inordinately high ( 150kg ), I don ’ t see any issues here .
The 12V system is comprised of two 100Ah lithium batteries , mounted to the offside chassis rail behind protective checkerplate . These batteries are connected to two solar panels on the roof . Wonder Roo has opted for the BMPRO BP35HA-II battery management system , which itself is hooked to the BMPRO Odyssey Link system . This system provides at-a-glance information on the 12V state of play , water tanks , etc ., via a digital display . It is , in my experience , a decent system .
