In 2020 we have released the worlds first wireless trickle charging wheel lights. Does this mean you will never need to charge the battery again? Not quite, but we are getting close.
Size Matters. The current generator is a little bigger than a quarter so it takes a lot of time to charge the battery.
How long does it take to charge the battery? - Our test showed 5-6 hours of driving charged approximately 1v on the battery. The battery is 3.7v. The battery voltage cutoff for lighting the wheels is 2.8v, so when voltage drops below 2.8v they won't light. You would need to ride approximately 5-6 hours with the lights off to get charged back to 3.7v.
How can I get the longest battery life? - As with many manufacturers we supply free batteries but they are not high performance batteries. The first thing we recommend is purchasing an additional set of high performance 3.7v Li-ion 16340 batteries. We do sell some decent ones on our website store so check them out. We also supply a free standard battery charger but, you may want to upgrade to a smart battery charger for faster charge rates.
What if the battery is dead can the generator charge it up? - As above, once the charge gets above 2.8v the lights should turn on, however if you have the lights on, the overall power drain from the lights may supersede the generators charging capability so it is best to use the battery charger to charge the battery back to 3.7v.
Do some light colors draw more power than others? - Yes, light different colors draw power at different rates. There are 3 diodes in each of the 6 RGB LEDs. These LEDs create colors by mixing 3 colors together. Red, green, or blue only use 1 diode, all the other colors require mixing light from all 3 diodes, per each LED. So colors like pink, cyan, yellow, and white actually uses up to 18 diodes in the 6 RGB LEDs!
What if I leave my vehicle in the garage and don't use it for a couple weeks, will the batteries go dead? - In order to keep the circuit boards active to respond to the remote control the circuit boards stay on in low power mode 24/7 listening. So even if you don't ever turn the lights on they may drain the battery in 7-10 days. We recommend purchasing an extra set of high performance 3.7v Li-ion 16340 batteries and always keeping a set charged to swap out as needed.
Long story short. This is the current technology of generators and batteries limited by the size we have to work with. We are always working to make them better Thanks for all your support as we continue to make the best possible wheel lights for your vehicle!
