Ordered 2 Efest 20700 3000mAh 30A Batterys a couple of weeks ago from IMRbatteries.com Put them in my new Wismec Reule rx2 20700 box. Using on power mode at 35watts. One battery is dropping like a rock. Well not quite. It didn't take the same charge as the other. Charge all my batteries in a 4 port Boruit c4. Charges my 18650 cells fine. The RX 2 uses the 18650 cells (they included sleeves for size adjustment) pretty evenly. But one of the 20700 batts just won't quite take the same charge. Question IMR won't take them back as stated on their web site so should I just keep charging them both and then recharge after the weak one reaches mid or 1/3 down or just spin the dice and buy both new again. Some where else.
Or look for a single 20700 box and use them ? What do Ya'll think?
