The information in this article applies to the semi-integrated battery that comes with some ebikes (e.g., the RadRhino 6 Plus and RadCity 5 Plus), and is intended to supplement the information in that bike's Owner's Manual, available HERE. For information on the external batteries that come with most other ebikes from Rad Power Bikes, please refer to that bike's Owner's Manual, available HERE, and the Help Center article on charging external batteries, located HERE.
Charging, storing, and using your semi-integrated battery
Please refer to your Owner's Manual. The latest version of that manual is always available HERE.
Mismatched charge indicator levels
Question: The charge level indicated on my battery and on my Rad UI Display don't match. Should I be concerned?
Answer: Probably not. If the two sets of charge indicators show only a slight difference in charge levels (e.g., a difference of one light), that difference is likely caused by variations in rounding to the nearest 10th percentile. A minor difference like that is fine.
If, however, the charge indicator lights on your battery and your Rad UI Display mismatch by several indicator lights, you may have a problem. Your battery indicator lights are calculated inside the battery itself and should be very reliable unless, of course, there is something unusual happening in your battery. Your Rad UI Display gets its charge-level information from the controller, so if the Rad UI Display shows erroneous data, you might have a connection problem or controller issue. In that case, check your wiring connections using the instructions in the RadRhino 6 Plus Connector Check Guide. If that doesn't solve your problem, remove your battery from your bike, store it and your charger in a safe location, and then contact Rad Power Bikes Product Support for help.
Should I replace my battery fuse?
Question: Something seems to be wrong with my battery. Should I replace a fuse?
Answer: You cannot change a fuse on these semi-integrated batteries. Fortunately, these batteries and their chargers are specially designed to prevent conditions that can blow a fuse, so it's extremely unlikely that you are having an issue that could be solved with a fuse replacement. Please consult the troubleshooting information here and in your Owner's Manual to pinpoint potential causes of whatever problem you're observing.
Question: Do I ever need to balance my semi-integrated battery?
Answer: No, you do not need to balance your semi-integrated battery unless Rad Power Bikes Product Support recommends it. These semi-integrated batteries stay well balanced under normal use conditions. Follow the use, charging, and storage instructions in the Owner's Manual, and your battery should provide you with excellent performance.
