So my Nightcore I4 charger has stopped working. I have quite a few Eneloops also the Ikea ones and have just tried some Aldi. AA plus AAA and some 18650. I don't need fast charge just whatever looks after the batteries best. I have an Aldi smart charger (Active Energy) 6 slot which seems to work well but doesn't take 18650. I am trying to understand the difference between the new Nightcore I4 and D4 chargers I do prefer one that gives an LED of the state of the battery
any advice appreciated
If you already have AA charging covered and only need a new one for 18650s then an economical option would be a LiitoKala-Lii charger - coupons for 1, 2 and 4 slot models can be found here - http://budgetlightforum.com/node/52142
They look a bit like Chinese rubbish but are actually quite good - http://lygte-info.dk/review/Review%20Charger%20LiitoKala%20L…
