High capacity industrial battery 21700 Enrone 4800mAh 48G, 9.6A
21700 Enrone 4800mAh 48G – industrial Li-ion battery of the 21700 form factor without protection. Thanks to new technology, Enrone INR21700 48G 1MA7 4800mAh batteries are capable of operating with average discharge currents:
up to 9.6A with continuous load;
up to 20A with short-term load up to 5 seconds;
up to 40A with short-term load up to 1 second;
These batteries have a LiNiMnCo composition, which allows them to operate with high currents without damaging the battery itself. In terms of characteristics, the Enrone 4800mAh 48G battery is in no way inferior to more expensive IMR batteries (such as Efest), but Enrone has a more “pleasant” price compared to the Samsung 21700 48G, LG M50LT 21700, Samsung 50E 21700 and Molicel 21700 M50A.
Original Enrone batteries that are available for retail sale have a QR code that allows you to read the model and production date.
Enrone 48G batteries are recommended for use in any devices with low and medium loads - they will work in electronic toys, power banks, portable vacuum cleaners, mechanical mods and other equipment.
Due to their high performance and relatively low cost, Enrone 48G (10A) batteries can easily be called leaders among current batteries of the 21700 format. The battery has a flat positive contact (Flat-top).

Enrone 21700 48G (9.6A) batteries do not have a protection board, and therefore require compliance with the following operating conditions:
Keep batteries 21700 Enrone 4800mAh 48G, 9.6A in a dry box. Do not charge above 4.2V;
Do not discharge below 2.5V;
Do not short-circuit the battery, observe polarity;
Do not store the battery at temperatures above 45°C, keep away from fire;
Avoid contact with water;
After long-term storage, several charge/discharge cycles may be required to reach the battery's nominal capacity.
Compliance with the above rules will make the operation of Li-ion batteries without protection safe and productive.
Basic conditions for using 21700 batteries:
Constant discharge current.
<10 Amps - low current (power banks, toys, low-power flashlights)
<16 Amps - medium current (power banks with fast charging, electric motors, high-power flashlights, medium-power tools)
>16 Amps - high current (power banks with fast charging, heating devices, powerful flashlights, electric motors, electric vehicles, powerful power tools)
When batteries are overvolted, they overheat and degrade.
Internal battery resistance.
This is an important parameter. The lower the internal resistance, the more current the battery can deliver, the less it will heat up. Heat above 80 degrees kills lithium batteries.
<20 mO – high current batteries
<35 mO – medium and low current batteries
>35 mO – batteries are degraded or have specific properties
Battery production date is 21700.
Chemical processes inside the battery do not stop. The higher the voltage, the faster the processes. The conservation voltage (waiting for the start of operation) should be 3.4-3.7V. New batteries must have the same series voltage and a voltage not higher than 3.7V.
<2 years from production date – new (subject to storage conditions)
>2 years from the date of production - 10% degradation (subject to storage conditions)
>3 years from the date of production - 15% degradation (subject to storage conditions)
>5 years from the date of production - companies send them for recycling. Check the production date to avoid purchasing batteries that have been sent for recycling.
