EEMB 3.7V 1800mAh 963450 Lipo Battery with JST Plug 2mm, 1PC

Battery was good

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

Great batteries amazing quality and read as the correct mah

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 ! !

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.

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.

I'm not sure what can be said about a lipo battery. The quality feels fine, it comes well packaged and charged no issues. I can't say much about battery life because I put it in a home made wifi light switch for my kids, but it lasts several days with the D1 Mini microcontroller.

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.

jag skickade tillbaka då det var fel storlek

Just tested it and it works fine. The quality looks good, the power cables are a good thickness and it's polarity is wired such that it works with Adafruit electronics. Other batteries I've bought have been wired oppositely and have thinner wires.

Al momento posso dire che è un ottimo prodotto.

Tout a fais conforme

J'ai déjà acheté plusieurs batterie LiPo EEMB et je suis toujours satisfait. Pour ce dernier achat cela m'a permis d'améliorer une sonde différentielle qui fonctionnait auparavant avec une pile 9V. Elle est maintenant équipée de cette batterie 1800 mAh couplée à un module chargeur / step-up convertisseur qui permet d'obtenir la tension 9V nécessaire. Le tout se recharge avec un chargeur de téléphone standard.
