Im looking for a simple affordable charger for two 21700s. I have one with 4 slots that I was using to charge my old 21700 but for what ever reason the new 21700 battery I got is slightly longer and I cant get it to fit in without nicking the wrap. I need one that has no issues with inserting the battery. Anyone know of one? thanks

@Ashuwixen I charge 21700’s all the time in my Opus.

right on looks like a good product. Have you ever had issues with some batteries being longer than others? Starting to think I bought a crappy new battery. ( M&A BD 50E-Green, 5000mAh 21700)

@Ashuwixen I’ve never measured them, and I think I have 3 different MFG’s of 21700’s and they all fit and charge in the Opus.

The Miboxer C4-12 has the longest slots I’ve found and there is plenty side to side as well which helps getting your cells in and out. It can charge at 3a across all 4 slots which is extremely rare and helpful charging the bigger cells faster.

This site is excellent for Charger reviews and also lists slot dimensions so you can make an informed decision.
