CUSTOMER APPLICATION CASE
7.4V 3350mAh 18650 Battery Pack for Wireless Timing Remote Control
A compact 7.4V 3350mAh 2S1P 18650 rechargeable lithium-ion battery pack is used to power a wireless timing remote transmitter designed for manual timing control in equestrian competitions and other timed sporting events.
Background / Application
Wireless timing remote controls are used in sporting events where judges or officials need to manually trigger start and stop timing signals. The handheld transmitter provides a convenient way to control the timing system when direct manual operation is required.
In this application, the timing remote is primarily used for equestrian competitions, including show jumping, dressage and carriage driving. Start-line judges can hold the wireless transmitter and manually send timing commands during competitions.
Similar wireless timing devices can also be used in canine sports, vehicle racing and selected outdoor competitions where manual timing control is required.
PKCELL Battery Solution
The wireless timing transmitter uses a 2S1P 18650 rechargeable lithium-ion battery pack with a nominal voltage of 7.4V and a capacity of 3350mAh.
The two-cell series configuration provides the 7.4V nominal voltage required by the device while maintaining a compact battery-pack structure suitable for integration inside the handheld remote control.
