A great seller. I'll buy from them again in the future.
Express delivery in 5 working days!
The batteries arrived within 7 days, production dates from August 2025, original codes, voltages are all equal at 3.291V, and they have balanced perfectly during operation. Highly recommended!
The package arrived even though I did not receive shipping information, so I couldn’t track it. Nevertheless, the product works perfectly and the initial tests are very promising. Highly recommended!
