I am constrained to the following: 3S lithium-ion battery of 2600 mAh charging at 1 A, USB-C connector with 5 V, the BMS is already included with the battery. My main question is if this solution will work and if this is the best way to handle charging given the constraints. Everything seems to check out with the Boost circuit and charger spec ...

Understanding the Context

Creating a 12.6 V 3S Lithium-ion Charging Circuit from 5 V USB-C How do I calculate the approximated time for the Charging and Discharging of the battery? Is there any equation available for the purpose? If yes, then please provide me. 2 Don't use a TP4056 for charging LiFePO 4 batteries; it won't stop charging until about 4.2 V has been reached and while some LiFePO 4 batteries will probably handle that without exploding, it could damage them and will shorten their cycle life (the number of times they can be charged and discharged without noticeable deterioration/capacity loss).

charging - Is it possible to convert a USB Legacy charger to support ... Introduction Various resources [1] [2] state that the optimal method of charging a li-ion cell -- such as one found in a mobile phone -- is to charge at a constant current (usually <1C) until a I'd throw out all the "charge-only" cables. As the other answers have indicated, charging over a cable with the data lines disconnected is slow at best, and overloads the port at worst. If you want to inhibit data communication, use a USB condom or one of its many clones that reproduce the power negotiation while blocking data. Charging lead-acid batteries with a power supply Lead-acid batteries can be charged manually with a commercial power supply featuring voltage regulation and current limiting.

Final Thoughts

Calculate the charge voltage according to the number of cells and desired voltage limit. Charging a 12-volt battery (6 cells) at a cell voltage limit of 2.40V, for example, would require a voltage setting of 14.40V. The ...
