About this item

  • Neat pins:Each polarity have a small pin so you can get the lowest possible height.This style of electrode provides minimal,negligible additional resistive loss due to contact resistance in comparison with spot welding and remain stable over time.It is be fine for a single-insertion use,and also good for use in different cyclic application in tight spaces.
  • Firm contacts:The metal contacts can keep the batteries slides forward all the way and makes full contact with the positive side terminal.Flexible enough that it doesn't pull off easily under reasonable force.Won't snap when faces with stress,won't give too much strain to the back and side walls after fully loaded,no considerable deflection in that case.
  • Independent slots:The last thing you want to see is the base to crack,the springs to pop out or the leads to be insufficiently connected.The slots is sturdy and flexible,batteries can stay in when held upside down.This is how you know the sides of the holder grip multiple cells well.Easy to get the batteries in and out of the fixture and very simple design.
  • Easy install:No need for tape or needle nose pliers.They comes without wires,you can use these primarily for parallel configurations or serial connection.Despite bottom is marked both positive and negative anodes,but there is no specific orientation so you can solder and load the batteries how ever you'd like.More possibility for your power arrangement.
  • Multi-Function:They are compact,durable and well made.If you have a battery operated wall clock that eats batteries quick,wire it to these bundle so you can charge it effortlessly.Feel free to replace the toy RC car's old battery pack with your own solution,soldered them to the back of the board,put some new batteries in,and now you got yourself a rechargeable battery management system.

Can these products be used at home and in classrooms?


Many products may be suitable for classrooms, home learning, science projects, maker spaces, and hobby activities. Suitability depends on the specific product, learning environment, user experience, and intended activity.

How can I check what is included with a product?


Please review the product title, description, specifications, images, package quantity, and included-components section before ordering. Items shown for demonstration or scale in product images may not always be included.

How do I know whether an electronic or robotics part is compatible?


Check the listed dimensions, voltage, connector type, board compatibility, operating requirements, and supported platforms. Compatibility is not guaranteed unless it is specifically stated on the product page. Contact us before ordering if you need clarification.

When will I receive tracking information?
