Firstly, If I’ve stuffed up the photos, please forgive a luddite.
I have 2 sets of back-up batts from an Optus high speed modem (Australia).
I don’t use them as the modem is hooked to a UPS. I’m guessing from the size they are 3 × 18650’s in the case.
The back says Pegatron Model PB 013. 10.95V/2600Mah, 28Wh Would it be possible to rig an adaptor cable from a Magic Shine type bike light cable to the pin for this casing.
Since I have 2 sets, I can recharge by putting them back into the modem
i don’t have any type of dedicated bike light as of yet.
Only began thinking about it when I rediscovered the batteries, and wondered if I could use them for something.
Any information or ideas are most welcome.
Most MagicShine lights use either 2S2P or 2S3P battery packs, both types are 7.4V nominal, and 8.4V off-the-charger. So I wouldn’t use 10.94V nominal / 12.6V off-the-charger pack with them, their driver circuits might not be designed for voltages that high.
I decided to take your advice scaru.
(After reading Shadowww’s post, I realised I would be in way over my head.)
Have pulled them out and this is what I have.
A few further questions if I may:
What is the best (and safest) way to remove the tabs?
Am I correct to assume they would be unprotected? They are a good 3mm shorter than my Trustfire flames.
I have a Trustfire TR-001 charger - will it be ok with these batts, or should I get something better?
I guess I’m a little edgy about unprotected batts since I’m a noob to all this.
Many thanks for any help
Yep, those are unprotected. I find it easier to use a pair of pliers to tear off the tabs. My personal method is to sit outside next to an ammo can full of sand and a fire extinguisher while I first clip all the wires and then I tear off the tabs.
From what I can tell those cells have a 2600 ma capacity
