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.

## 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.

### ⭐⭐⭐⭐ Check your Polarity!!
*by M***K on July 12, 2022*

I paired this with an Adafruit LiPo charging board and the polarity was reversed on the battery compared to the charge board!!! Make sure you check the polarity of the battery input on your charge board or what ever device you are putting the battery in. You can look at the end of the JST connector and compare them like the picture shows. Swapping the polarity on the connector is really easy! Use a pick or razor blade and lift the little pin lock (red arrow points at the plastic locking tab) and then slowly pull the pin out making sure you do not short it across the other pin! Once you have them both out swap which hole it was in and just push it back into the JST connector and you will feel it snap lock into place, you can verify it locked by lightly pulling on the wire to check it. Once you have both pins back in with the correct polarity you are good to go!
