hello, I don't know wich version of enertia basic I have. I live in Spain, I bought it in the second hand market. My enertia doesn't have central button and no need to block it for charging. It does charge right and the pannel lights when charging. Two things I don't understand of charging, the lights are always on and there is no button to switch it off, maybe for european homologation?. When charge range is close to 96% a noise inside the batteries is on and doesn't stops even after 100% charge. Please could someone tell me which Enertia version I have? is it that noise normal? thanks
