This is the lithium battery pack balancers available to me: As Robojax has extensively explained in this video, this module is capable of balancing batteries with 67mA current (4.2v/62ohm) that is way too slow for my application because my charging current is 500mA and this causes over charge of batteries before the balancer gets the chance to balance them. So I thought I might be able to use a high power resistor (or array of low power resistors) to increase power of the module. For example use a R8.2-5W or 5xR43 2512. Both solutions provide 500mA current and have good power margin for sustainability. The mosfet used in this module is A2SHB that can handle up to 3.7A.
Is there anything that I'm missing here? Why the balancer modules does not come with such resistors to be able to handle more current?
