High current capable 20700 industrial cell from Sanyo/Panasonic. Developed for the power tools sector (impact wrenches, drills, circular saws, etc.). Best suited for: Industrial applications, model making, etc.
For single cell applications for end users (battery carriers, torches etc.) we have the Panasonic/Sanyo cell with plus safety from Enercig.

Sanyo/Panasonic NCR 20700C up to max. 30A constant current output.

The advantages of a 20700/21700 cell are basically one: due to the larger volume of the cup cell, the performance can be significantly increased compared to the smaller 18650, even with identical "technology". In other words, an increase in performance without too much development effort.

Technical data of the Sanyo/Panasonic NCR20700C

Safety instructions:

Lithium cells may only be operated with protective electronics!
Please note that lithium cells may only be used by authorised specialists.
Incorrect handling or short-circuiting may result in fire or explosion.

Further characteristics:

Lithium-ion batteries are thermally stable and are not subject to any memory effect.
They work on the basis of lithium and are characterised by a high energy density.

Notes:

A special charger is required for charging lithium-ion batteries, which charges the batteries according to a special charging procedure. (CCCV = constant current, constant voltage.) The batteries must not be charged above a voltage of 4.2 volts, otherwise there is a risk of fire and explosion. It is advantageous to charge the batteries only up to approx. 4.1 volts, as this significantly increases the service life or the number of charging cycles (possibly up to double). Only lithium ion chargers may be used for charging. However, the cheap chargers sometimes have the disadvantage that they do not switch off safely at the end of the charging process, but continue to charge the batteries with a small charging current, which can be dangerous.

Furthermore, rechargeable batteries and batteries do not belong in household waste! Please dispose of them as prescribed by law at the municipal collection points or in the [usually green] containers provided by retailers.
