Got my drone going

Works perfectly fine with no issues whatsoever. Bought this to power the Volantex/Eachine warbird 400mm planes that I have. Even though they state 400mah as the same value as the stock batteries that comes with these planes, I have noticed a higher motor output and longer flight time so I use these batteries instead now. No issues with swelling batteries etc. Obviously as these are 1S 25C batteries charge them once they have cooled down after use, not immediately after to prevent damage.

These lipos are good value, efficient items. My Eachine 400 mm warbirds would no longer work with their original lipos and now are rejuvenated. I am very pleased with Roaring Top!

This product is extremely dangerous. The battery are prone to explode-they will swell in size and pop, squirting acid out from the sides of them. I am sure this item does not meet any safety standards. I recommend you do not purchase this product.

Great quality,great that charger can charge all 5 batteries at once Very good price and quality.

I bought these to replace a drone battery that had stopped charging, and chose them as they’re listed as the identical size to the one I have. The batteries that have come are much smaller, and won’t have the capacity to run the drone for any length of time. I have included pictures showing the size difference. These were listed as 39mm long, but they’re actually only 30mm, and very slightly smaller in width also.

Come da descrizione .misure corrette

1 stella perché non mi piacciono le menzogne ed altri si affidano a quello che vedono scritto nella descrizione del prodotto. Rispetto una vera 400mah, pesano 5 grammi in meno, lunghezza e altezza sono uguali ma lo spessore è inferiore. Ancora non le ho provate ma penso che la durata della carica sia nettamente inferiore alle vere batterie 400mah.

prodotto non soddisfacente , non utilizzabile per durata. inoltre 3 batterie su 5 si sono gonfiate in fase di ricarica...mi meraviglio che vengano commercializzate.....forse uno stock difettoso.
