KBT 3.7V 800mAh Li-Polymer Battery: 702250 Lipo Rechargeable Lithium-ion Replacement Batteries with JST Connector

The KBT 3.7V 800mAh Li-Polymer Battery has garnered mixed reviews from customers, showcasing both its adaptability and shortcomings. Many users appreciate the lightweight and compact design of the battery, which makes it a favorable option for custom applications like ring lights and motorcycle intercom systems. Some customers have reported successful installation in existing devices, even noting that the battery fits well after slight modifications, despite being a bit larger than the original unit. However, a common point of concern is the variability in JST connector sizes. Several users found that the connector on the KBT battery did not match their devices, leading to compatibility issues and requiring additional soldering to integrate the battery. Furthermore, while some users were pleased with improved run times when combining multiple batteries in parallel, others reported disappointing performance, with the KBT battery providing significantly less runtime compared to their original batteries. This discrepancy in battery life suggests that while the KBT battery may function adequately in some scenarios, it might not meet expectations for high-demand applications. In summary, the KBT 3.7V Li-Polymer battery is a versatile option for those willing to adapt their devices. It works well in lightweight applications and can even extend runtime in custom assemblies. However, potential buyers should be aware of compatibility issues related to JST connectors and the possibility of reduced runtime compared to factory batteries. **
