The 26650 EFEST 26650 5000 mAh battery… The 26650 EFEST 26650 5000 mAh battery actually tested a bit higher than its rating. I think this is the first time I've had that good of a result from a battery I've tested. Quick shipping and a good price too!

Batteries nicely packed. Batteries nicely packed in individual little boxes. They had not been charged for a while though. All were about 3.5 volts. Really quite dead. I have always read that LiNiMnCoO2 chemistry cells should be stored at about 40% SoC or about 3.65 to 3.7V. Perhaps in long term storage the voltage range is lower. Some air shipment rules also specify lower SoC. I'll give them a full charge, and run a discharge test. Thanks for the good service.

Amazing with a tiny downfall It came super fast. Only thing that I didn’t like was there was no way to check on my order through m&a. All together good purchase

This company is a rip off I ordered… This company is a rip off I ordered battery and they where no good I call email and they never respond

Unhappy first time customer. I purchased a Efest Luc v8 from M&A BD Electronics and in just a few weeks multiple bays stopped charging and if they did charge it would dangerously over charge the batteries. I contacted them for a replacement and all they've done is pass me off to the Efest company. After contacting Efest I was told that M&A BD Electronics should have replaced the faulty charger per warranty and contacted them for reimbursement. It's been 2 weeks of sending emails and videos to M&A BD Electronics per there request. Now they have completely stopped all contact with me. I paid good money for a expensive Efest charger to a company that doesn't care about the customer. All they care about is collecting your money and moving on to the next sell. Stay far away from M&A BD Electronics.
