BATTERY CHARGING SAFETY
Overnight charging and consecutive balancing are safe to do as the Onyx CTY2 stock charger and onboard battery
management system provide redundant fail-safe mechanisms. As the battery charge level (5 amps) arrives at 97%
(70.78 volts) the charger will reduce its amperage output substantially lower and begin trickle charging. In turn,
reducing its heat output and shutting off its cooling fan for the remainder of the charging, trickle charging, and also
during the battery balancing.
NEW BATTERY BALANCING
Battery balancing is available on the Onyx CTY2 although it is not available on most e-bikes. Battery balancing serves
the purpose of equalizing the voltage between all 85 individual battery cells inside the Onyx CTY2 battery. When a
battery is balanced, 100% of its capacity is available, whereas an unbalanced battery provides less than 100% of its
capacity and causes premature battery degradation. Balancing occurs automatically when the BMS detects an
unbalanced situation.
BATTERY BALANCING
Battery balancing refers to techniques to improve the available capacity of the battery and/or increase the battery’s
capacity and keep the battery safe. Variations in battery cells come from a number of factors including cell age,
environmental exposure, impurities.
