  • Helmet bluetooth
Size: 602248 (620mAh)
Battery for my Bluetooth helmet started to no hold a charge. Looked up batteries and this one said it would fit. It was a smidge bigger than the stock battery but swapped over the connector, plugged it in, charged it and now my helmet works fine and I can ride and enjoy my music again. Great purchase. ... show more

  • Fits perfectly in Featherweight Tracker ground station - BUT SWITCH THE POLARITY!
Size: 112945 (1400mAh)
I searched high and low for a higher capacity 1s LiPO that would fit the little battery compartment in this tracker ground station. This one fits perfectly. The connector has pos and minus switched (It's for UAVs which have the opposite polarity). It's easy to change it, do not push down on the metal locking tabs, pry up on the plastic locking tabs, pull the wires out, switch them, push them back in. Perfect. ... show more

  • Good capacity, great size, great price.
Size: 702030 (350mAh)
I was happy to find the specific size this battery comes in. There aren't many options with the capacity and the size this comes in. So this was a great find for me. I also got a charge with a voltage regulator and they worked fantastically together. I will be buying more of these to use for my upcoming projects. ... show more

  • Pleased with fit and performance
Size: 403048 (500mAh)
My very handy shirt pocket oscilloscope had an unusual battery size, but when my battery failed, the seller did not have a replacement. The Amazon sourced battery I bought isn't the exact shape as the OEM, but the new one fits fine, has the same current capacity and operates exactly the same as the old battery (when it worked). The new battery has completely restored the operation of my scope, charging and discharging as before. The new battery did not have the same connector as the old, but it was an easy task to cut off the two connectors and swap them. Having a battery that fits is a whole lot cheaper than buying a new scope. I really like the many different sizes and shapes offered by Amazon. ... show more
