Description

Tenergy T4s Intelligent Universal Battery Charger + 4 x Panasonic NCR18650B 3.7V 3400mAh Lithium-Ion Rechargeable Batteries combines a four-bay intelligent universal charger with four high-capacity Panasonic NCR18650B rechargeable lithium-ion cells. Each Panasonic NCR18650B battery is offered in this bundle as a 3.7V, 3400mAh rechargeable lithium-ion cell. This bundle provides a convenient charging solution for compatible rechargeable battery applications requiring the correct 18650 cell format, voltage, terminal configuration, and electrical characteristics.

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 supports selected lithium-ion (Li-ion), lithium iron phosphate (LiFePO4), nickel-metal hydride (NiMH), and nickel-cadmium (NiCd) rechargeable batteries. Individual yellow LED indicators display charging status, while automatic charge termination, reverse-polarity protection, and short-circuit protection help manage charging. The charger accepts AC 100-240V, 50/60Hz or DC 12V input and provides output voltages of 4.2V, 3.6V, and 1.48V for supported battery chemistries. Maximum charging current is 425mA per slot with four occupied slots or 850mA per slot with one or two occupied slots.

The four included Panasonic NCR18650B 3.7V 3400mAh lithium-ion rechargeable batteries use constant-current/constant-voltage (CC/CV) charging at 4.2V, with a manufacturer-specified standard charging current of 1625mA and a discharge cut-off voltage of 2.5V. Panasonic specifies maximum bare-cell dimensions of 65.3mm in length and 18.5mm in diameter, with a maximum weight of 48.5g. The manufacturer-specified charging temperature range is 0°C to +45°C, and the discharging temperature range is -20°C to +60°C. The exact finished-cell dimensions, terminal configuration, and any added protection circuitry must match the supplied batteries and the intended equipment. These rechargeable lithium-ion cells must not be substituted for 1.5V AA batteries, 3.2V LiFePO4 cells, or nonrechargeable lithium batteries.
