Great Product

June 4, 2021

We use these in all kinds of battery powered designs. They are robust, protected, and we have never had any issues. We use the Tenergy Universal Smart Charger for charging. We also abuse them a lot during prototyping and development, they stand up to what ever we throw at them. Very satisfied with Tenergy products in general.

Quick to Fail

January 8, 2021

One cell of the pack failed during the second charge, rendering the pack useless. I cannot recommend this product to anybody.

Perfect Replacement for Carrera Remote Control Car

July 10, 2020

The batteries for my Carrera remote control cars were obsolete. These are a little bigger but still fit. Works great and as a plus the cars runs even longer than before. Very happy. Delivery was also very quick

from Frisco, Texas asked:

March 17, 2015

Hi, I am interested in purchasing this product at some point under one condition, do you sell a device to recharge it? If so, can you provide me with a link to it (I should note that it is in some sort of case that the batteries cannot be taken out of, so I need something I can just plug in the red and black terminals into to recharge.) Thanks.

1 Answer

We recommend the Tenergy TLP-4000 Universal Smart Charger for Li-Ion Battery Packs.
