BTS SOL 4200 Lumen Dive Light Kit With Charger

  The perfect most POWERFUL freedive spearfishing light. It's powerful enough to light the reef, but lightweight and compact. I don't like the extra weight of carrying a big light & it's not the best for your breath hold...besides you should save that energy for carrying back your lobster :)  Lobsters can be light shy, so we recommend using the low setting. This will also ensure a longer runtime of 13 hours! Smart Multifunctional Battery Charger one-slot charging and management system with Micro USB DC5V input port. 500mAh/1000mAh charging current for selection. Built-in LED indicator shows the charging status 25%-50%-75%-100%. Identify Li-ion and Ni-MH battery automatically. You must set the charging mode to Li-Fe when you charge LiFePO4 battery or 3.85V Li-ion batteries. (Identify 1.2V Ni-MH/3.7V Li-ion Battery automatically and select manually for 3.85V battery Li-ion and LiFePO4 batteries). Refresh function for 0V battery. Can't charge batteries of type 1.6-2.2V.
