Looking for a Way to Extend Battery Cable

Greetings!

I am using a ‘Lenovo Legion Y530-15ICH’ laptop, but more importantly, the battery inside is the original ‘L17L3PG1’ ( Li-ion | rating: 11.34 V | TYP 4630 mAh/52.5 Wh | MIN 4498 mAh/51 Wh).
Upon unplugging the 12-pin connector of the battery from the motherboard, I figured out that the laptop is indeed fully capable of working at maximum performance without a battery, so only with the power supply.

I was thinking of extending the cable of this battery, and I need at least 20 centimetres of extension for this (because I want to use this battery outside of the laptop on my own responsibility). There is no information printed on this 12-pin connector. → Picture about the 12-pin connector
(Actually, the batteries called ‘L17C3PG1’ and ‘L17M3PG1’ have the same connector.)

• Does an extension cable exist for this purpose? (With a female connector on one side, and with a male connector on the other side.) If yes, can it be purchased? (If such cable does not exist, how can the 12 cables be extended at home with proper equipment?)

• From a technical and electrical point of view, is it safe to extend the 12 cables of the battery this way? Is it safe for the connections?

Thanks for the responses in advance!
