used this to replace battery in hyperx cloud 2 wireless headset
This works great and boosted the longevity of the talk time. I had to remove the connector and use a 10k thermoresistor but this is working and charging effectively. So a good replacement

Watch Out for the Polarity ID Colour !!
Why these batteries have the connector plug fitted the opposite way around to all of the connector leads available, is a bit of a mystery. And a massive pain in the chunks.

Great quality product
Fantastic battery, installed in a speaker that appeared to be dead. fitted new battery and hey presto it's working again. Really good price and super fast delivery.

Works as advertised
Neat little lipo, comes with a little protection board wired in. Keeps a small meshtastic node going all day. Should be fine for any little low-current project that might not fit an 18650 in the box.

Perfect for SparkFun PCB's
The polarity of this battery is not the conventional (most common) but for those looking for this special requirements, this is perfect. SparkFun does nor ship batteries to the UK so getting the correct polarity can be difficult. Great battery quickly delivered.

Thank goodness I checked the POLARITY !
Whenever I have bought lipo batteries from this manufacturer EEMB the polarity of female connector attached to the battery has always been the correct way for fitting it to the male connector on my lipo charger BUT I ALWAYS check it before connecting them together . Just as well I am into this habit because on this pack of 4 1800mAh lipos as the connections had been reversed on the battery ! Therefore I could neither charge them nor use them on the circuit I had previously used 850mAh lipos on and needed the extra mAhs to make the circuit last for longer as it is a red/green/blue changing led solar charging light . So I have wasted a lot of money due to lack of Inspection at the factory . Not a happy bunny ! ! UPDATE - VERY IMPORTANT ! ! Since I posted this review I have been contacted both by the Seller & by EEMB explaining to me that there is NO industrie standard for polarity of battery to connector . I have been offered a full refund without returning the batteries . I now realise that our reviews ARE read by Sellers and Manufacturers . Please Note I have altered my * rating from 1 to 3 because the Seller/Manufacturer contacted me with their explanation as to why the polarity was different to other EEMB connectors . Just remember to always check the polarity of the battery and the piece of equipment before connecting the battery ! I have taken up their offer of a full refund ! One Happy Bunny ! !
