Hello,

All of our 4S chargers can be found in the link below. However, i'll need some more clarity on your required charge current

Hi,

To summarize, you battery termination voltage is 4*4.2V = 16.8V and your A-hours are 300Whr/16.8V = 17.9Ahr. For 1.5 hour charge time, you need more than 17.9Ahr/1.5hr =11.9A charge current. If you have at least 19V power source for the charger, you could use the BQ24610. To get the high charge current, you will likely need to add FET gate drivers.

Regards,

Jeff
