Description

Tenergy T4s Intelligent Universal Battery Charger + 4 x 18650 3.6V Lishen 3000mAh Li-ion Batteries (Button Top) combines a versatile four-bay intelligent charger with four high-capacity Lishen rechargeable lithium-ion batteries. Each included Lishen 18650 battery provides a nominal capacity of 3000mAh, a nominal voltage of 3.65V (commonly marketed as 3.6V), and a raised positive button-top terminal. This rechargeable battery bundle is designed for compatible equipment requiring 18650-format lithium-ion cells and provides a convenient solution for charging and maintaining rechargeable batteries.

The Tenergy T4s Intelligent Universal Battery Charger features four independently controlled charging slots, allowing compatible rechargeable batteries to be charged individually or simultaneously. Its microcomputer-controlled charging system automatically manages charging according to the supported battery chemistry and condition. The charger supports lithium-ion (Li-ion), lithium iron phosphate (LiFePO4), nickel-metal hydride (NiMH), and nickel-cadmium (NiCd) rechargeable batteries. Individual LED indicators display charging progress, while automatic charging termination, short-circuit protection, and reverse-polarity protection contribute to safe operation when the charger is used according to its instructions. The T4s accepts AC 100-240V, 50/60Hz or DC 12V input and supports charging currents of up to 425mA per slot with four occupied slots or 850mA per slot with one or two occupied slots.

The bundle includes four Lishen 18650 3000mAh lithium-ion rechargeable button-top batteries, each featuring a specified 4.2V charging voltage, 2.5V discharge cut-off voltage, and maximum continuous discharge current of 15A (5C). Each battery measures 65mm in length and 18mm in diameter, with a listed weight of 48g (1.69 oz). The button-top terminal is designed for equipment requiring a raised positive contact. These batteries offer rechargeable performance, high energy density, and no memory effect. Before installation, verify the equipment's required battery voltage, dimensions, terminal configuration, discharge-current requirements, and protection-circuit requirements. The presence of an individual protection PCB is not specified for these Lishen cells and must not be assumed.
