Unlike traditional linear chargers that generate excess heat, the TP5100 utilizes a 400kHz switching buck topology, allowing it to deliver up to 2A of charge current while remaining incredibly cool and energy-efficient.\u003c\/p\u003e\n\u003cp\u003eAvailable at Tomson Electronics, this module is a massive upgrade over the standard TP4056 for high-capacity applications. It features a wide input voltage range of 5V to 18V, making it highly versatile for use with various power supplies, solar panels, and DC adapters. By default, the module charges 1S batteries at 4.2V, but it can be easily configured to charge 2S battery packs at 8.4V simply by bridging a single solder pad on the board.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeople also search for:\u003c\/strong\u003e tp5100 charging module, 2s lipo charger board, 2a lithium charger, tp4056 alternative, 8.4v battery charger, tp5100 1s 2s.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMain IC:\u003c\/strong\u003e TP5100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Voltage Range:\u003c\/strong\u003e 5V to 18V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Voltage:\u003c\/strong\u003e 4.2V (1S - Default) or 8.4V (2S - Configurable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Charge Current:\u003c\/strong\u003e 2A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitching Frequency:\u003c\/strong\u003e 400kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection Features:\u003c\/strong\u003e Over-current, over-temperature, and battery reverse polarity protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStatus Indicators:\u003c\/strong\u003e Dual-color LED (Red = Charging, Blue\/Green = Fully Charged\/Standby)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eApplications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Capacity Power Banks:\u003c\/strong\u003e Rapidly charging large single-cell lithium arrays where 1A chargers are too slow.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobotics \u0026amp; RC Vehicles:\u003c\/strong\u003e Creating built-in charging circuits for 7.4V (2S) battery packs used in motors and servos.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePortable Audio:\u003c\/strong\u003e Powering and charging custom Bluetooth speakers utilizing 2S battery configurations for higher amplifier voltage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolar Charging:\u003c\/strong\u003e Harnessing 12V solar panels to efficiently step down and charge lithium batteries in remote IoT nodes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eFrequently Asked Questions (FAQ)\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I change it from 1S (4.2V) to 2S (8.4V) mode?\u003c\/strong\u003e\u003cbr\u003eA: On the top of the module, there is a small pair of solder pads labeled \"SET\". By default, these pads are disconnected, and the module outputs 4.2V for a 1S battery. To switch to 8.4V for a 2S battery, simply use a soldering iron to bridge (connect) the two \"SET\" pads together with a blob of solder.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is TP5100 better than the TP4056 module?\u003c\/strong\u003e\u003cbr\u003eA: Yes, for higher power applications. The TP4056 is a linear charger maxing out at 1A, which means it burns off excess voltage as heat. The TP5100 is a switching charger, meaning it efficiently steps down the voltage, generates far less heat, supports up to 2A, and has the added benefit of supporting 2S batteries.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this module protect the battery from over-discharging?\u003c\/strong\u003e\u003cbr\u003eA: No. The TP5100 is strictly a battery \u003cem\u003echarger\u003c\/em\u003e. It does not feature built-in low-voltage disconnect (over-discharge) protection for the load. You will still need a separate BMS (Battery Management System) attached to your battery pack to protect it during use.\u003c\/p\u003e\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × TP5100 1S\/2S Lithium Battery Charging Module (2A)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"-","offers":[{"title":"Default Title","offer_id":48336972316910,"sku":"BAT-29090","price":69.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/Tp5100-Module-768x768.jpg?v=1784292689","url":"https:\/\/www.tomsonelectronics.com\/products\/tp5100-1s-2s-lithium-battery-charging-module-2a","provider":"Tomson Electronics ","version":"1.0","type":"link"}
