The charger in use is the SLM6900, which has this store. The translated datasheet is here. My board will flow as follows: USB-C ⇾ 5 V to 12.6 V boost circuit ⇾ 3S charging circuit --> battery Here is the 5V ⇾ 12.6 V boost schematic Here is the 3S charger circuit Below is the full schematic Another option I found is this product SLM6803.
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).

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 will design a charging circuit for an ICR26650 3.7 V Li-Ion battery. I'm considering using the BQ24070 chip in the design. The battery charging voltage of this chip is given as 4.2 V. Datasheet I...
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.
