100 Pcs 18650 Lithium Battery Cell Holder, Battery Storage Box
Quick take
This 100-piece set of plastic 18650 cell holders is designed for DIY lithium-ion battery packs, where you need a consistent way to space and support cylindrical cells. Buyers highlight that the holders clip together easily, line up cells neatly, and provide space for nickel strip connections. The biggest buying caveat is fit planning, you will still need to carefully align clips and confirm your exact cell and pack layout requirements.
Pros and cons
Pros
- Bulk quantity (100 pieces) for building or rebuilding DIY 18650 packs.
- Clip-together design helps separate and line up cylindrical cells.
- Built-in spacing that leaves room for nickel strips during assembly.
- Hole diameter is listed around 18.4mm, made specifically for 18650 cells.
- Card-slot edge design allows combining holders and using 18360 spacers.
Cons
- Alignment matters during stacking, if the connections are off the next layer may not fit correctly.
- Plastic cell holders are aimed at DIY support and organization, not a complete protective enclosure by themselves.
- Best for 18650-only or 18650 plus spacer workflows, it is not a universal battery mount for other cell sizes.
What buyers think
Buyer-review evidence is positive but concise. The most consistent themes focus on assembly usability and pack layout. Multiple reviewers describe the holders as easy to use and as doing a good job separating and lining up 18650 cells, especially once clips are connected correctly. Several comments specifically mention that nickel strip space exists between cells, which can make the DIY build process more straightforward. There is also limited evidence that careful attention to connection alignment is important to ensure upper layers fit properly. Overall, buyer-review evidence is limited in detail, but the direction is clear: these holders work well for the basic job of holding and spacing cylindrical 18650 cells during a DIY pack build.
What this battery holder is for
These 18650 cell spacers and holders are intended for DIY lithium-ion battery packs built from cylindrical 18650 cells. The design emphasizes physical spacing and consistent placement, which matters when you are trying to keep cells stable while adding nickel strips for series or parallel connections and when you want an organized pack layout instead of using loose adhesive or makeshift supports.
Key specs that affect fit
- Designed around 18650 cell size: The listed hole diameter is 18.4mm (0.7 inch), which is meant for 18650 cylindrical cells.
- Bulk count: Includes 100 holders, which suits multi-cell builds or users planning to rebuild or experiment.
- Combining system: The edge includes a card slot to connect holders together, and it can also be combined with 18360 battery spacer pieces (for mixed workflows).
- Cell spacing and connection room: Reviews mention space in between cells that supports nickel strip connection work.
- Material and use case: The holders are described as plastic with impact resistance, heat resistance, and electrical properties, aimed at safer organization for DIY battery packs.
Pros and cons for real DIY builds
Pros that matter during assembly
- Neater layout: Clip-together holders help keep cells separated and aligned, making it easier to build a structured pack.
- Simplifies strip placement: The spacing between cells is a practical benefit for nickel strip connection, reducing the “cells shifting while you work” problem.
- Sturdy once assembled: Reviewers specifically describe the assembled holders as sturdy.
Tradeoffs and buyer-fit considerations
- You still have to assemble carefully: If connections are not lined up properly, stacking can become difficult and the next layer may not fit right.
- Not a full battery case: The holders focus on cell spacing and support. If your project needs a sealed or fully enclosed battery pack, you will likely want an external enclosure or protective housing design.
- Cell size verification is on you: The holder is intended for 18650 cells, so confirm your cells match the intended diameter and your pack plan is compatible with the holder geometry.
Who should buy this
- DIY battery hobbyists building small to medium 18650 packs who want a consistent mechanical layout.
- Builders who prefer organized nickel strip connections and want built-in spacing between cells.
- People who need a large quantity (100 pieces) for multi-cell configurations or iterative rebuilds.
Who should skip it
- If you need a finished, enclosed battery pack: these are holders and spacers, you will still need an enclosure and appropriate battery protection components for a complete system.
- If your project uses non-18650 cylindrical cells: this set is sized for 18650 workflow.
- If you want minimal assembly effort: clip alignment is straightforward, but you do need to pay attention during stacking to avoid fit issues.

Alternative approaches to consider
If you are comparing options, choose based on what you value most for your pack build:
- For the cleanest DIY layout: similar clip-style holders or spacer systems are typically the easiest path to consistent spacing for nickel strips.
- If you only need a few cells: buying a smaller quantity kit can be more cost-effective than a 100-piece bulk set.
- If your priority is full enclosure protection: look for cell holder systems that integrate into a complete protective battery case or enclosure design, so you do not need to engineer the outer shell separately.
Bottom line
The 100-piece 18650 cell holder set is a practical choice for DIY builders who want cells separated, aligned, and spaced for nickel strip connections. Expect the main success factor to be assembly alignment, take your time clipping and stacking, and you should get a cleaner, more stable pack layout than loose or adhesive-only methods.
FAQs
Are these holders compatible with 18650 batteries?
Yes. They are made for 18650 cells, with a listed hole diameter of about 18.4mm (0.7 inch).
Do they leave space for nickel strips?
They are designed with spacing between cells, and buyer feedback commonly mentions that there is room for nickel strip connections during assembly.
How do these holders connect to each other?
The edge includes a card-slot style connection, allowing holders to be clipped together into the size and arrangement you need.
Can I combine these holders with 18360 spacers?
The design supports combining with 18360 battery spacers using the card-slot connection on the edge.
What is the main downside to watch for?
Alignment during assembly matters. If the connections are not lined up correctly when stacking layers, the next layer may not fit as expected.
Will this replace a full battery enclosure?
No. These are cell holders and spacers, focused on organizing and supporting the cells. For a complete battery system, you typically still need an appropriate outer enclosure and proper battery protection components.

Comecase Battery Organizer Storage Case, Battery Vault Carrying Container Bag review
The Comecase battery organizer storage case is a high-capacity, EVA foam-lined holder designed to keep AA, AAA, C, D, 9V, and button-cell batteries separated and easier to find. A removable BT-168 digital tester is included to quickly check 1.5V and 9V battery power, but it is not meant to replace a charger, and the organizer can be a bit labor-intensive to set up when you first remove the foam pieces.
(Pack of 2 4 AA Battery Holder with Leads, 4 AA Battery Holder with Wires
These dual 4-AA battery holders are designed for projects and repairs where you need a clean, simple AA pack with pre-attached red/black leads. They output 6V (4 x 1.5V AA) and come with short 5.9 inch leads, so they work best when your wiring distance matches up.
(Pack of 2 2 AA Battery Holder with Switch, 2X 1.5V AA Battery Holder Case with Wire Leads and ON/Off Switch)
This pack includes two 2-AA battery holders with built-in ON/OFF switches and red/black wire leads, designed for projects that need a compact, wired power input. Buyers like the fit-and-function for repairs and replacements, but the included screws may be tricky because they can be too small for the holder depending on how you mount it.
FULLCASE Battery Storage Organizer Holder Holds 54 AA AAA Batteries, Box Cases Garage Container, Home Drawer Organization Dispenser (Case Only) Grey
The FULLCASE battery storage organizer is a compact, latch-closed plastic case designed to hold up to 54 AA and AAA batteries (case only). Buyers use it to tame loose batteries in drawers, keep cell types separated, and quickly see what is inside without opening. The main caveat: it is made for AA/AAA storage, not a universal mix for every battery size.
