Multi-Cell 2S 3S 4S Type-C to 9V/12V 4.5V-15V Step-Up Buck Fast Charging Charger Module for 18650 Lithium Battery

Hign-concerned Chemical : Noneis_customized : YesCondition : NewType : ModuleBrand Name : Ziqqucu : Mainland ChinaFeatures:This product is a module with wide application and multiple innovative application designs. It has been maturely used in high-power power bank applications and has charging in boost and buck modes.Supports charging of multiple strings of lithium batteries, and the battery can be charged regardless of whether the input voltage is higher than, lower than or equal to the battery voltage.Built-in fast charging input protocol, battery charging is divided into three stages: precharge, constant current, and constant voltage process.Supports fast charging, can induce 9V/12V., 4.5V-15V wide voltage input, and supports 1-5 series battery charging.Charging voltage can be set by resistor to support multiple strings of lithium batteriesParameter Description:1: Small size, high power, 3A high current, maximum power 18W (not exceeding this power).2: 4.5-15V power supply, can be used for step-up and step-down charging of 1-4 strings of lithium ion/lithium polymer.3: Adaptive charging current adjustment, suitable for charging with all USB interfaces.4: Built-in input fast charging protocol, configurable 9V or 12V input protocol.5: Intelligent pre-charge, constant current, constant voltage, with short circuit protection.6: Automatically charge in boost or buck mode according to changes in input voltage and battery voltage.7:3-color LED charging status indication indicates charging, full, and fast charging.8: Working environment temperature range: -20℃～85℃.9: Scope of use: multi-string lithium battery charging, high-power power bank, modified solar charging10: Multiple specifications:2 strings full of 8.4V3 strings full of 12.6V4 strings full of 16.8VInstructions:The module input can be a type-c interface or one of the direct soldering wires. The voltage is 4.5-15V. It can be 1-5 strings of lithium batteries or lithium iron phosphate batteries. The battery must have a protection plate and can automatically balance the voltage. Just better. If the input uses fast charging, you can set 9V input for two strings, and 12V input for three or more strings.Precautions:*Please do not connect the battery reversely or connect it to the anti-burn board.*Connect the charging head before connecting the battery and test whether the module charging light displays normally.*The wire cannot be too thin, the charging current cannot keep up, the wire must be welded.*The battery must have a protective plate.*When the module power is high, the heat will be greater. Be careful to fan the module and do not use materials that are not easily exposed to heat to seal the module.Checklist:1X moduleUse Q&A:1. What fast charging protocols does the product support?Answer: Currently, it supports the most common QC protocol and is supported by most fast charging sources on the market.2. Does the module generate a lot of heat?Answer: The heat generation varies depending on the charging power. When the charging power is relatively high, the heat generation will be relatively large, which is normal.
