Review: Seems high quality so far. - I got this for an airsoft pistol and learned that said pistol needed higher voltage to run properly. Said pistol uses a faux extended magazine to house the battery, and this one was a reasonable fit. I'm a bit disappointed it didn't work out, but I have plans for this battery. I own and operate some 3D printers as a hobby and this battery will work great for a few LED lamp projects I have in mind, but I digress. I appreciate the fact that this battery has a built in low voltage cutoff, though I have no intention of testing it. I see a lot of folks use this for microcontroller applications though I can't comment on this battery's efficacy there. For test running LEDs with a buck converter, this battery is working great, it has a much higher capacity compared to the numerous tiny single cell Lithium batteries I have laying around, yet it's compact enough to fit in portable lights. As for the battery connector, I again can't comment. I removed the molex connector that came with this battery and soldered a Deans connector onto it's leads (after testing it on my programmable charger with the molex connector on) and I haven't had any issues. I'm very pleased with this battery, and should I ever need one like this for a future project, I'll gladly order another one.
Review: Batterijen - Ik ben tevreden met de snelle levering van de accu's, alleen bij mij zijn niet helemaal oke. De accu's willen niet fatsoenlijk laden, en zijn naar mijn idee zeer snel leeg.

## Questions & Answers

**Q: I’m guessing the crossed polarity issue that many are reporting, stems from the JST connector’s orientation & not the wires, correct?**
A: Yes, the wires are correct polarity. Wrong location in the JST connector. I just popped the pins out of the connector and reversed them.

**Q: Will this battery replace a GSP6532100 (30) battery for a blutooth speaker?**
A: If it fits and the wire connection fits, it will work

**Q: how is this battery charged?**
A: I have a cable that came with the original battery. It has a matching connector for the battery and the other end is a standard USB that plugs into an adapter like you would use for a phone or other device.

**Q: Is it necessary to use a special charger/balancer for safety?  the battery i’m replacing is in a device that simply has a micro usb input.**
A: I went by the spec’s 
“PCM protection function: over charge, over discharge, over current, short circuit protection.”
My purpose was to have my vacuum robot last much longer!
I strung 4 of these in series to match the voltage in the robot, and then glue gunned them to the top of my Shark IQ Robot vacuum.  I got these flat packs specifically so the robot would still be able to go under furniture Then I connected in Parallel, the 4 batteries that I had in series, to the built-in four 40-60’s internal to the robot. I let the robots built-in charger do the rest. The robot went from about a 45 minute total run time to over 3 1/2 hours. It is now able to complete the whole house in one pass!  It’s set for every other day and has been successfully doing this for the last 7-9 months. Works outstandingly well. Neither battery pack gets even slightly warm. However it does take 3 times as long to charge, But it's got all night.
