Need advice on this Battery / Charger combo. Is it the right one for me?

Hi Everyone! Thanks for reading.

Currently I have a cheap ebay type laser that take 3.7V 18650 batteries. I'm planning on building a "real" laser in the future that will accept 18650 batteries. I want to purchase decent batteries now in the hopes that they will serve me well in multiple future builds.

After reading the forums, I've settled on this battery and charger:

Battery: Panasonic NCR18650PF 2900 mAh (x2)

Charger: Nitecore Intellicharger i2 Universal charger

Questions:

1) Will these batteries work in my current laser and also in future builds? I plan on making a 405nm and 532nm lasers first!

2) The price I will pay for the charger and 2x batteries will be about 30 USD including tax and shipping. Is this a reasonable price?

Thanks,
Frozen

Yes the Nitecore are good chargers that is what I use I have an i4 and the cells are good as long as they are genuine.:beer:

Thanks for the reply!

I've placed the order for the charger. Its from a authorized distributor, so I'm fairly confident that I will receive a genuine product. The battery on the other hand I'm buying from ebay. Based on the seller's rating and number of people who are happy with their purchase I can hope that the battery will be legit. Is there any way to tell its authenticity once I receive the product?

Thanks,
Frozen
