FeiLong BT303-11 Battery Charger for LiFeP04 3.2V / Li-ion 3.7V Batterie

It\'s a bit of a departure from the Li Ion battery chargers that are most common out there. First it can charge up to six 18650\'s or three 26650\'s at one time. 26650\'s \"-\" side rests on both of the negative output springs and are common linked together per channel. The \"+\" output of the charger I received is slightly different then what is pictured only in that there isn\'t a raised nipple like the picture seems to show. Flat top batteries depending on their manufacture need a conductive spacer if really flat. I have two types with one flat but protruding out a slight bit that work without the spacer and others that need them. The free standing power pack supply\'s ample power when fully loaded to capacity so it\'s easily as fast as other chargers I have WF 139 being just one of them. Power pack label reads 12V 4A output. Smaller number of batteries charge quicker but not like one battery will at six time the speed. I got this charger mainly because I got a flashlight that uses three 26650\'s and the others ones I have didn\'t feel safe having one battery haphazardly stuffed in it. They are 6000mAh and don\'t take a unreasonable amount of time to recharge three at once. One glitch on the power pack is I needed to open it up and put a small amount of heat resistant material inside to take up room because of a rattle but a five minute at best fix so not deducting anything for that. The car adapter has got to be the best one I\'ve ever seen. It\'s seriously beefy made and six feet long with indicator power led. I\'ve had this charger now going on four months as of writing this review and had rapidly become my number one go to charger within two weeks of owning it. Because of the tree 26650 capability and not at a snails pace, Yes I would most certainly buy again. If for only 18650\'s ... Yeah I probably would because it\'s gotten nice to not have multiple chargers going and taking up the additional top space and power cord tangle.
