Can I run two lifepo 100ah batteries in paralle, which have 2 different max charge currents?

Problem is, the only spec I am finding hard to match on new battery I wish to purchase (to run in parrelle with the one that I already own,) is max charge current. One is 100a and other is 50a. Is there any way that this can work?

it should work if your charge current does not exceed the smaller charge current in your case 50a.

what are using to charge your batteries?

Parallel in accordance with best practices in Victron Wiring Unlimited.

Limit total charing to about 70-80A and confirm the flow through each battery with a clamp DC ammeter.
