PSA: Chosty.com is having a 7/10 sale including Hopper batts, both GHB3 and 2’s dressed in 3’s clothing, LOL.
What’s a Hopper? I haven’t used mine in months. Not even sure my latest set of batts can hold a decent enough charge. I was never fond of the Hopper batteries and had a few duds over the years, and I found their performance just OK and not great like 18650s. I’ve mostly moved on from them but still have both my Hoppers, an original and a IO. What can you do?
