Well, another year has gone by, and my second eBay battery started showing signs of weakness. I followed the link I posted above for my first batteries, and they showed out of stock. I tried Luga’s link from January 2021, but the link was broken. But I searched for 601430 and found what looked like a suitable battery, and ordered it. This latest one was narrower but thicker than the ones I used before, and the thickness made it hard to get the Clip closed, but it is working.
One other difference between the various battery versions is how the tabs are arranged (the spots you solder the wires to). On this latest battery, the tabs are very close to each other, which raises the risk that you will short out the battery when doing the soldering. So that is one more factor to consider when buying one of these generic batteries.
For the record, here is the link to the eBay listing:
And the product description:
3.7V 200mAh 601430 Lithium Polymer LiPo Rechargeable Battery (USA STOCK)
The product picture shows the battery with a connector already attached, but the connector was not included.
