MP2632B with External charger

Battery Management
1

Hello,

I would like to use MP2632B in our application where we use a 100Ah single cell battery to output 5 V at 1 A. However, since the maximum charging current of MP2632B is only 3 A, this means the charge time will be 100 Ah / 3 A = 33 hours, which is too long for our application.
What I want to know is, how can I use an external fast charger like this

which connects direct to the cell to charge it faster.

Are there any issues with charging the cell this way? Is there a risk of damaging the IC or other components? How exactly do I need to connect the external charger to the cell to prevent damage?

Regards,

Samo Smodiš
