This listing is for the LG M52V 5,200mAh cell. Compare each cell’s documented current and temperature limits with the exact device requirements and intended power setting; capacity alone does not establish mod suitability.
The LG M52V is a high-energy cell. Its documented discharge ratings depend on temperature: 15A from 10–25°C and 7.5A from 25–55°C. The calculations on this page use 7.5A as a conservative assumption.

- Fits
- Compatible only with an exact regulated device that accepts this cell and meets all manufacturer battery requirements. Low selected wattage alone does not establish suitability.
- Use this cell only in equipment whose manufacturer specifies a compatible removable 21700 cell and supports its dimensions, terminal type and continuous-discharge rating.
Does not fit
- The VOOPOO Drag 5 Mod Kit 177W Dual 18650 and any other 18650-only mod. A 21700 is too large for the bay
- Any mod whose maker specifies a minimum discharge rating above 7.5A
- Any mechanical mod
For help choosing a cell, send the exact device model, intended wattage and the cell details on WhatsApp. Check the device’s required cell format, terminal type, electrical limits and physical fit, as well as the cell’s rating and condition. Dual-cell devices require a suitable matched pair.
For more capacity again at a similar discharge rating, the Vapcell F60 21700 6000mAh 12.5A Battery is the other runtime cell on this shelf.
An excellent cell, built for a different job
LG lists M52V at 5200mAh typical capacity and 3.69V nominal voltage. Check the exact model and documented operating limits.
What it was designed for is runtime at modest current. LG’s high-energy 21700 line goes into e-bikes, power banks, torches and stationary storage, applications that draw a few amps for a long time rather than thirty amps in bursts.
What 7.5 amps supports, in watts
At an assumed 3.2V per cell and 90% conversion efficiency, the page’s continuous-current model gives about 22W on one cell or 43W on two. These are conditional calculations, not universal safe-output ratings or device approval. Check actual voltage, efficiency, temperature, cell limits and every exact device requirement, with an appropriate margin.
Those are real, usable figures for a low-power device. They are also a long way below what the three mods in the Vapesoko range are rated for, and it is more useful to say so than to leave a customer to discover it.
For comparison, a single cell driving eighty watts is being asked for around twenty-eight amps, and two cells driving two hundred and twenty want about thirty-eight apiece. This cell is at a quarter of the first figure and a fifth of the second.
Where it belongs
Match this high-capacity cell to equipment whose exact current, temperature, physical and electrical requirements it meets. Capacity alone does not establish runtime or compatibility.
LG M52V capacity
This listing is the LG INR21700 M52V with a typical capacity of 5,200mAh. Match the exact model number when comparing specifications.
Charging it
LG publish real numbers for this one: a standard charge current of one and a half amps and a maximum of three and a half. Charging at the standard rate rather than the maximum is kinder to the cell and asks nothing of you but a little patience.
Charge to four point two volts and no further, discharge no lower than two and a half, and use a charger with independent bays and an automatic cut-off. Indoors, hard surface, not unattended overnight.
The same physical care as any lithium cell
Sixty-seven grams of cell in a thin plastic wrap, with a live metal case and an insulator ring at the positive end doing the work of keeping them apart. Check both before every insertion.
Re-wrap a damaged sleeve properly rather than taping it. Retire a cell that has been dropped hard or dented. Carry loose cells in a plastic case and never alongside coins or keys.
Reading a datasheet rather than a wrap
Check the exact cell model, discharge conditions and device requirements when selecting a battery.
That is the difference between a cell from a company that manufactures cells and a rewrap such as the Efest IMR 18650 3000mAh 20A Battery, whose real figure had to be established on a bench. The figure is documented, temperature-banded, and consistent with independent modelling. It is simply a lower figure than a vaper usually wants.

A high-drain 21700 has arrived
Vapcell lists P42A at 4200mAh and 30A continuous discharge, while this listing uses 5200mAh and 7.5A. Compare current requirements as well as capacity; those numbers alone do not establish comparative runtime. Reference: Vapcell P42A 21700 4200mAh 30A Battery.
