Hello,
I'm looking for rechargeable batteries for 4x 5V motors of nominal current draw 1.2A and peak current up to 3A to power my robot.
I'm wondering about 2x3.7V Li-Ion 2000mAh or 5x1.2V NiHM batteries.
What is you opinion?

NiMH batteries withstand much more abuse that Li-based batteries, and are less picky about how they are charged.
Thanks for the reply. I have this simple linear charger 5* TP4056 5V Micro USB 1A Lithium Charger Module Battery Charging Board Hot for sale online | eBay , do I guees right NiMH can't be charged by it even it they are "lees picky"?
You should always use a charger intended for the battery type and capacity that you choose.
Lithium will be capable of a lot more current though. Try to find manufacturers' datasheets for
rechargable NiMH's if you can, they are not as high current as NiCd, in general, so be warned - you
need 6+A for your motors if you don't want the battery voltage to dip.
