FITHOOD 103450 Battery 3.7v 1800mAh Lithium Polymer Rechargeable Battery with JST Connector for Household Appliances

This was just what we needed to fix our walkie talkies! I did have to re-wire because the plug was wired backwards for what we needed. Has been working flawlessly since.

As a musician, I thought I was going to have to toss the purchase of a music stand light (Vekkia), or keep it continually plugged in to use, which I can't do when traveling. It would no longer hold a charge after six months of original purchase. With this affordable battery replacement, easy to replace, I'm back up to a fully functional light, holding a charge for many uses.

As an avid electronics/maker hobbyist, I use quite a few of these LiPo batteries for various projects. They pack a lot of capacity in a very lightweight "pouch" that's generally easy to work around. As with any lithium-based battery without a hard enclosure, you must use caution not to cut or short these batteries as they can quickly heat up and catch fire or leak chemicals that are generally bad for you.This little 1800mAH battery seems to work as well as others I've used. It includes a 2-pin JST connector so I don't have to add one. I'm pleased with it so far.

i cannot determine the cause of the fault from this battery or from my headlamp charging circuitry.the headlamp wasn't receiving any juice even when i hooked the charger up for long time.so i thought it could be the battery going bad and replaced with this one seeing that the specification meetsbut the lamp still didnt workso i dont know if the charging circuitry inside of the lamp was bad or this new battery was defective.since the headlamp is not working and considering the price of the lamp itself; its not worth investing anymore $ to rejuvenate the lamp.however i am writing this review to provide a data to someone out there having a suspicion with the product that their devices repeatedly fail when replaced with this battery could bring some hypothesis that this battery might be defective in its nature of quality.

Just took way too long to arrive. I think because it comes from overseas. But other than that it worked great.

I ordered this battery to replace an old and worn-out LiPo battery in my LED headlamp unit which barely holds the charge. I use this LED headlamp for camping and hiking, and I am impressed by the performance and quality of this battery. I installed it easily and my LED headlamp came back to life. The headlamp now lasts over 2 hours on a single charge and works just like new. The brightness and beam distance are also improved.One important thing to note is that sometimes the wires in the connectors are reversed and not all manufacturers follow the same standards. I have seen cells having the wires in reverse, which may damage the end equipment. So, make sure of the polarity before you replace your old cell with the new cell. You can use a multimeter or a polarity tester to check the polarity of the wires. Generally, the red wire is positive, and the black wire is negative. If the wires are reversed, you can either swap them or use a different connector (need crimping and soldering skills).The cell charges to its full limit and I have not observed any overheating or swelling. It does what the specs say. It has a capacity of 1800mAh and a voltage of 3.7V. The JST connector fits most household appliances and devices. Overall, I am very happy with this LiPo battery. I think it is a reliable and long-lasting replacement battery for my LED headlamp and is reasonably priced. I would recommend this battery to anyone who needs a new LiPo battery for their LED headlamp or other devices.

This battery delivers the advertised capacity, and is a good value for small projects, or repairing anything that needs one about this size.

I've had a lot of experience lately with different types of lithium polymer batteries for home projects. One thing that's surprised me is how inconsistent some of them can be. Hooking this up to a microcontroller I'm seeing none of the power fluctuations that other lipo batteries seemed to generate.Which is great! Makes everything a whole lot easier. No complaints!
