Q1: What is the difference between Flat Top, Button Top, and Nickel Tab?
A:
Flat Top has a flat positive terminal, compatible with most modern devices (flashlights, power tools).
Button Top has a raised positive terminal (like a standard AA battery), required for older devices and certain battery holders with spring-loaded contacts.
Nickel Tab comes with nickel strips pre-welded to the positive and negative terminals. This is ideal for DIY battery pack building – no soldering required, just spot welding or direct connection.
Q2: Is this battery suitable for mechanical mods?
A: Yes. The DMEGC 20P's 20A continuous discharge makes it a reliable choice for mechanical mods and sub-ohm builds. Its 2000mAh capacity provides shorter but adequate runtime for most sessions. Always check your device's wattage limits and follow proper battery safety guidelines.
Q3: How does DMEGC 20P compare to Samsung 20S?
A: Both have similar 2000mAh capacity and 20A discharge. The DMEGC 20P offers a more affordable price point while delivering comparable performance. It's a great value alternative.
Q4: Is this battery protected or unprotected?
A: This is an unprotected cell. It relies on your device's built-in BMS (Battery Management System) or protection circuit to handle overcharge, over-discharge, and short-circuit protection. This provides maximum flexibility for use in devices with built-in protection.
Q5: What charger should I use?
A: Use a dedicated intelligent Li-Ion charger designed for 3.7V/4.2V cells. Do not use universal chargers designed for NiMH batteries. Look for chargers with overcharge protection and temperature monitoring features.
Q6: How should I store these batteries?
A: Store at 40-60% charge in a cool, dry place away from direct sunlight and extreme temperatures.
Free Shipping: Enjoy free shipping on all orders over $65. For orders under $65, the shipping cost is $8.99.

Ordered button top DMEGC 20P for a custom triple LED light high drain allows turbo. Slightly tight fit but ok.
I used these in a high-performance brushed motor setup for an RC truck. The 20A burst current gives it huge acceleration. Highly recommended for hobbyists.
I bought 4 of these to build a 4S pack. They were all within 0.02V of each other out of the box. Excellent QC from DMEGC for such high-drain cells.
20A discharge is amazing, but 2000mAh means you run out of juice faster. If you need raw power over runtime, these are the ones.
I specifically ordered the version with nickel tabs for a spot-welding project. The tabs were securely welded and took solder very easily. Great quality.
