I’m considering using one of the following battery packs
Products : Lithium-ion Battery Pack (14.80V, 5.2AH)
Model: Samsung ICR 18650-26H M(18650 5200Ah 14.8V 4S2P)
Products: Lithium-ion Battery Pack (3.70V, 10.4AH)
Model: RS Pro ICR 18650-26H M(18650 10400 Ah 3.7 1S4P)
Could you please let me know if you have any suitable Battery Charger ICs that I could use.
