Review on Long-Lasting EBL 9V Lithium Rechargeable Batteries With USB 5400MWh Capacity (Pack Of 2) by Antonio Lemm
Inflated capacity - my new review
Full charged one via USB and discharged with an IMAX B6AC v2 professional charger / discharger down to 6.4v (3.2v per cell as this is li-po 2s). As seen in the picture measured capacity is 493mAh. With a nominal voltage of 7.4v this amounts to only 7.4×493 = 3648.2 mWh and not the claimed 5400 mWh. The manufacturer needs to specify discharge rate used for measuring capacity. Due to this I canceled the second order of these batteries that I placed.Adding an extra star for the customer service. EBL provided me a new set of batteries after the initial review. However the issue remains. Their other non-USB 9v Li-Po 2S battery (model 6F22) has a capacity close to the claimed value at the 1C discharge rate.
- Powerful Lithium Batteries
- May not be cost-effective for infrequent use
