so i just purchased a smart solar 75/15 and my guestion is do i need to do anything like remove the jumper thats on 2 of the small pins if im just using the app to change battery type to lithium? sorry i have to ask but it is confusing of how its written in the instruction booklet, it states" remove the jumper when using Bluetooth to configure the device" but i just want to change the battery type via the app to lithium and not change any of the advanced voltage settings so do i still need to remove this?
