For battery cells, review the product description for real-world current recommendations, testing notes, and application guidance. Manufacturer maximum ratings should be treated as limits, not the best target for long-term pack health.
Description
4-Slot 18650/21700 Tester Holder Assembly
Choose the connection configuration that matches your DIY500AMP 8-channel lithium battery tester setup. Each option uses a four-position cylindrical-cell holder platform designed for stable cell contact during charging, discharging, and capacity testing.
Configuration Options
- Wiring-Finished: preassembled version with individual screw-terminal connection points.
- Connector-Finished: connector version with the board connection points shown in the selected variant image.
Features
- Four independent cylindrical-cell positions
- Spring-loaded contacts
- Clearly marked positive and negative polarity
- Supplier-listed for 18650 and 21700 lithium-ion cells
Compatibility
Designed for the 8-channel 18650/21700 lithium battery tester sold by DIY500AMP. Each assembly supports four cells; order two assemblies for all eight channels. Compatibility with other testers should be confirmed by comparing the connection method and physical dimensions.
What's Included
One four-slot holder and connection assembly in the selected configuration. Tester electronics, display or control module, power supply, and cells are not included.
Safety
Use only with compatible test electronics and observe cell polarity. Never install damaged, leaking, or hot cells. Capacity testing can generate heat; operate on a nonflammable surface with adequate ventilation and supervision.
Orders ship from Florida when inventory is available. Lithium-ion cells require proper handling, protected packs, correct chargers, and safe storage. Do not solder directly to battery terminals.

One of my cell orders was short one cell
One of my cell orders was short one cell. When I went to send a text to the customer contact (this is rare and awesome way to reach out), the reply on a national holiday came within 15 min. That level of customer service is incredible, like family. I really appreciate that!

Wow, these cells are great!
I purchased some of these tabless cells to try on my 1S 3" HD Toothpick drone build, and, albeit a bit heavy for 1S, it flies pretty well. Not a freestyle monster, but an endurance beast with decent send. These cells shrug off the demands of a BETAFPV Matrix HD AIO flight controller/12A ESC and some 1202.5 11000KV motors. I'm getting 15+ minutes of speedy flight time from a single cell trying not to go below 3.2V, and about 20+ minutes cruising. Love these cells and will definitely buy more when time comes, only from DIY500AMP, who are terrific!
