Alternative for 7.4V Lipo 2500mAh Battery for Devastator ?

Hello,
I would like to buy the Devastator Tank Mobile Robot Platformon on the website, but i've seen that the battery 7.4V Lipo 2500mAh Battery (Arduino Power Jack) is discontinued due to delivery restrictions. ( https://www.dfrobot.com/product-489.html )
I am a novice in robotic and i don't know which battery with which charger i should buy instead that who would be compatible with the specifications of the robot. Can you help me ?
I just need this advice to finalise my order.
Thanks.
You can order from

you can also try

which may be helpful.

I've found my alternative :
1 - 2 x 18650 Battery Holder with DC2.1 Power Jack : https://www.dfrobot.com/product-1695.html
2 - Charger : https://www.dfrobot.com/product-1693.html
3 - 2 Turnigy 18650 2000mAh 3.7V Rechargeable Li-ion Batteries
Just need an USB sector charger.

Greeting: you can buy any 7.4V Lipo battery together with its charger. In worst case, you can even power it with 5 or 6 AA battery which is much easier to get, all you need is a AA battery holder.
Something like this should work with your projects.
