The recharge cycle of lithium-ion batteries varies, and it is limited. When it comes to power storage ability, An average 21700 battery with 5100mAh stores about 3 aH to 5 aH that is, it can store 15 to 20 watts hours. We, however, don’t recommend the use of these batteries. Unprotected batteries can only be used when the load and the charging are monitored and controlled externally. They are usually cheaper than protected 21700 cells. Unprotected 21700 batteries: The unprotected 21700 batteries are the ones that don’t come with the protective electronic circuit. They normally come with a button top, but it’s advisable to check the specs to be sure. A protected 21700 battery is safer than the unprotected one as it’s less likely to burst or cause a fire outbreak. This protects the battery from overcharging, overheating, over the current, short circuit, and discharge.
