18650 3200mAh Li-ion Battery for Livestock GPS Trackers
Large livestock farms need reliable location tracking to reduce animal loss, improve pasture management, and lower daily labor costs. In this customer application case, a single-cell 18650 3200mAh Li-ion battery with built-in PCM protection is used as the dedicated power source for livestock GPS collars used on cattle and sheep.

Background / Challenge
A large-scale cattle and sheep farm managing more than 20,000 livestock needed a more reliable power solution for its GPS tracking collars. The farm was facing three major problems: animal loss, high manual management costs, and the short service life of traditional small batteries.
For livestock GPS trackers, battery performance directly affects tracking continuity. If the battery runs out too quickly, the farm may lose real-time location visibility, geofence alerts, and the ability to respond quickly when animals leave the designated pasture area.
The customer needed a battery that could support:
- Long standby time under daily positioning mode.
- Stable performance in cold winters and hot summers.
- Outdoor use in rain, mud, dust, and pasture conditions.
- Shock resistance against collisions caused by livestock movement.
- Peak current demand during GPS signal transmission.
- Lower annual replacement and maintenance cost.
Solution
PKCELL supplied a single-cell 18650 3200mAh ternary lithium battery with a built-in PCM protection circuit as the dedicated power supply for livestock GPS collars. Compared with traditional tiny batteries, the 18650 format provides higher capacity and better suitability for long-standby outdoor tracking applications.
Under a daily four-time positioning mode, the battery can support approximately 12-14 months of standby time, helping the farm reduce the frequency of battery replacement and related labor work.
The battery solution is also designed for demanding pasture environments. It can work stably from -20°C to 60°C, making it suitable for mountain pastures with cold winters and hot summers. With shockproof and IP67 waterproof characteristics in the tracker application, the power system can better withstand outdoor rain and collision from livestock movement.
During GPS signal transmission, the battery provides stable high-current discharge to help prevent voltage drop, supporting reliable tracking and geofence alarm operation.
Actual Benefits
- 68% lower annual power cost compared with disposable lithium manganese batteries.
- 95% lower livestock loss rate through real-time geofence alarm and improved location visibility.
- Reduced battery replacement workload across a herd of more than 20,000 animals.
- Improved tracking reliability in outdoor pasture conditions.
Why PKCELL?
Livestock GPS tracker projects require more than a standard battery cell.
