"These are not lifpod4 batteries btw. They are using the old lion tech. 300-500 full cycles. More if you dont drain the battery all the way down".

JerseyEbiker - So can the case be opened up and lifpod4 batteries installed at a later date? Also, approximately how many average miles can I expect with the Kysmo on a full charge with the current battery? On my iZip Trailz, I get about 14 miles (with pedaling) on a full charge using one SLA (RMB) battery.
