Will these work?

[Daishi]

So Giving up trying to boost my batteries, unsure if I'm just ill equipped, doing it wrong, or the cell is just dead. So as an alternative to the shipping costs for 2 batteries racking up to 40 bucks -_- I was curious if these would work in a "SRD bellicose w/ Quick disconnect on a Li-ion setup" as well as the default charger?

The 14500 900mAH 3.7V all match up

I'm unsure what PCB and "protected board" means but if that means "protected" in the context of how this site uses it I'd probably have found what I'm looking for.

 http://www.amazon.ca/TrustFire-900mah-Rechargeable-Battery-Protected/dp/B00KTTFJ9Y/ref=sr_1_1?ie=UTF8&qid=1416699067&sr=8-1&keywords=Trustfire

Can anyone confirm based on this information of they would work without any probelms in my saber?

Hi.  Checked the Cdn. amazon site and they seem to be the same batteries.  The seller could have a higher satisfaction rating.  I would wait till you get more feedback from those members who would know for sure.

From reading the info on the batteries I have in my sabers, PCB is most likely 'Protection Circuit Built-in'

I don't see any differences between that listing and the batteries I've got, so if the price is right for you then you may as well order them.
