LG 18650 HG2 3000mAh 20a
available at my fave supplier
I've used a couple of cycles already. Subjectively outperformed my Panny NCR's, but on top of better performance, main selling point for me is they're actually 18650s! (65.21mm).
Others may know the 18650s vary to over 69.2mm length.
Happy customer.
