From Team Yokomo:
A new series of Yokomo lithium polymer batteries is now available! The redesigned HV Li-po series is, as its name suggests, HV (high voltage) specification. The rated voltage has been increased from 2 cells/7.4V to 7.6V, and combined with a discharge rate of 100C, it has an unprecedented power feeling.
The case size is the same as Yokomo’s previous short size Li-po, and while the case length has been further shortened, it has achieved a large capacity of 4200mAh using the latest manufacturing technology. This is a state-of-the-art battery that achieves high power and long runs, making it ideal for radio-controlled cars, and can be used in any category, from drifting to speed to off-road.
