Lithium renders the battery icon at the device's scale rather than the current app's scale. This causes issues in apps that have not been updated to support the device's resolution. Below is a screenshot of Speedtest, an app that has not been updated for the iPhone 6 Plus' resolution, running on an iPhone 6 Plus.
iOS provides no way to determine the scale of the app currently running (as opposed to the scale of the device) so there is no real way to properly fix this.
