Big Blue 21700x4 Supreme Battery Charger

Description

The Supreme Pro runs the larger 21700 cell, which is why it needs a different charger from the Supreme despite the two packs looking alike at a glance. This is the charger for the four-cell 21700 Supreme pack, and it fits the TL3800P Supreme Pro and nothing else in the range. Getting the right one matters more than usual here: the Supreme takes a four-cell 18650 pack and its own charger, and the two sets are not interchangeable in either direction. Charging the pack as a single balanced unit is the only method a sealed assembly allows, and it is also what keeps capacity even across the pack's life rather than letting one cell drift and drag the others with it. A spare pack without a second charger only shifts the bottleneck, so the two are usually bought together. It suits a TL3800P Supreme Pro owner turning packs around between dives.
