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
Charge, compare and prepare rechargeable cells for storage with the four-slot VC4SL. Its LCD display and dedicated grading and storage modes make routine battery checks easier.
Features and compatibility
- For 3.6V/3.7V lithium-ion and 1.2V NiMH rechargeable batteries, including 18650 and protected 21700 cells.
- Manually selectable charging current from 0.25A to 3A, with a maximum of 3A in one slot. Available current depends on the number of cells and power supply.
- USB-C input with QC3.0 support. Use a suitable QC3.0 adapter and cable for maximum charging performance.
- Grading mode measures discharge capacity; storage mode prepares compatible cells for storage. Internal-resistance readings are comparative references, not a substitute for laboratory testing.
What's included
XTAR VC4SL charger and QC3.0-capable USB charging cable in original XTAR retail packaging.
USB wall adapter and batteries are sold separately.
Battery safety
Use only the supported rechargeable chemistry and observe polarity. Check each cell's manufacturer charging limit before selecting a current; the charger's maximum is not a recommended rate for every cell. Do not charge damaged, leaking, swollen or overheated cells, or cells with damaged wrappers. Do not use disposable batteries, 1.5V lithium-ion cells or LiFePO4 cells. Charge on a nonflammable surface in a dry, ventilated area, away from children and combustible materials. Do not leave charging unattended. Stop use if a cell or charger becomes unusually hot.
Manufacturer warranty: 24 months for qualifying defects, subject to XTAR's terms. For support, contact support@diy500amp.com.
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!
