EEMB Lithium Polymer Battery 3.7V 3700mAh 103395 Lipo Rechargeable Battery Pack with Wire JST Connector for Speaker and Wireless Device- Confirm Device & Connector Polarity Before Purchase

EEMB Lithium Polymer Battery 3.7V 3700mAh 103395 Lipo Rechargeable Battery Pack with Wire JST Connector for Speaker and Wireless Device- Confirm Device & Connector Polarity Before Purchase

Q: I’m guessing the crossed polarity issue that many are reporting, stems from the JST connector’s orientation & not the wires, correct?

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?

If it fits and the wire connection fits, it will work

Q: how is this battery charged?

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.

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.
