EEMB Lithium Polymer battery 3.7V 1800mAh 103450 Lipo Rechargeable Battery Pack with wire JST Connector-confirm device & connector polarity before purchase

Although the capacity was the same as my previous one it was much larger but thankfully still fitted into my dash cam (just). So far, very pleased.

Great value

More or less the same physical size as the original battery in my Nextbase GW322 Dashcam. Only two wires on this replacement battery whereas the original has 3, the extra wire being for a temperature check I think. In any case, connecting up just the positive and neutral works ok. This new battery is supposed to be 550mAh and the old one is 280mAh so it should last a lot longer. We will see….

I am amazed that I have come across a battery that hold the milliamps that is printed on it case, I test all my batteries nowadays as there are so many overblown claims out there, after a five charge / discharge cycle, I got a 540mA reading from my tester, I'm sure if I had done another cycle it would have reached the full capacity, I installed it as a replacement battery into a Cosmo robot, which is working fine after over a month by a very decerning but picky owner.

Great lasts ages, improved my product immensely

Be aware that the battery doesn't have any protection for overcharge

This item arrives and didn’t work

Easy to install works well and delivers all of the power I need for my RC boat. Charges up well and it was well packaged and delivered in a good time and at a great price.
