Orbtronic IMR18650 2250mAh (Black)



Official specifications:

• Bare cell: made by Panasonic-Made in Japan
• Chemistry: Li-Mn/Li-Ion
• Type: 18650 IMR Hybrid
• Dimensions: 18mm x 65mm
• Capacity: 2250mAh
• Cell model: CGR18650CH
• Voltage: 3.7V
• Recommended full charge: 4.17V - 4.20V
• Max Discharge Current: 10A (high-drain)

With this battery I included tests up to 10A, where it still has lot of useable capacity. The battery does keep the capacity very well at high loads.















Conclusion

The battery uses a good cell, making it a fairly safe cell, but remember it is unprotected and must not be over discharged. For uses with high current this is a very good battery and it can deliver more capacity at a higher voltage than 3100 mAh cells when working with high currents.
