This 18650 lithium battery protection board is engineered for 7.4V and 8.4V setups, providing fundamental safeguards to help maintain battery health in various electronic projects.
In practical scenarios, it's useful for integrating into DIY battery packs for items like LED lamps, solar-powered devices, or 12V electronics, where it helps prevent overcharging and short circuits, potentially extending the lifespan of your batteries.
- Compact size: 35x16.6x2.5 mm, allowing for easy installation in space-limited designs
- Overcharge protection at 4.28V ± 0.05V to avoid voltage spikes
- Over-discharge cutoff at 2.9V ± 0.05V to protect against deep discharge
- Maximum working current of 3A, with peak instantaneous current up to 5A
- Low quiescent current under 3uA for minimal energy loss when idle
- Short circuit protection with delayed self-recovery for added safety
- Requires a charging voltage of 8.4-9V for compatible operation
This board fits well in low-power applications such as massagers or monitoring systems, but it's important to ensure it matches your specific voltage needs for reliable performance.
