Can I put a 100a BMS in parallel with a 200a BMS

[2mk2b3y]

I have a 200ah lithium battery with a 100a BMS. Can I add another 200ah battery with a 200a BMS with a 2000w inverter to run a 1800w conduction cooktop?

As long as the batteries are the same chemistry and cell count that will be fine.

I've been running 2 200a and 1 300a in parallel with no issues.

Welcome the the forum.

Should be fine.
What is your concern?

Working flawlessly - 250 A, 200A, 60A and 80 A BMS in parallel for more that 2 years. All LiFePo4 of cors.
