PROTECTED or IMR BATTERY: Which is best for your application?
IMR Li Mn. Lithium manganese batteries. Also called "high drain", "safe chemistry", "unprotected".
These are used in regulated mods that use buck boost circuitry to achieve variable voltage-wattage, but they are now also recommended for single voltage mechanical mods as a safer alternative to protected Li Ion batteries. Why High Drain Batteries?
This class will have less capacity in mAh rating compared to protected batteries, but are superior when maximum load current is required, such as in regulated mods, mechanical mods using a Kick, or using an RBA.
Hybrid batteries.
New mixed chemistry batteries that are both safe chemistry/high drain and extended capacity in one.
A good choice for applications that demand both maximum load current and longer battery time. Can be used for either mechanical or regulated mods.
Protected ICR Li Ion. Lithium ion class batteries, also called "protected batteries".
These batteries use a built-in protective circuit because they contain volatile chemistry that can become unstable quickly when they are severely stressed. Circuit failure can lead to battery failure, venting violently with flame in an event called thermal runaway. These batteries have a higher capacity (mAh rating) than IMR batteries and have been used in single voltage applications in a mechanical mod with factory-built coils. Not recommended for regulated mods, RBAs, or use in a mechanical using a Kick.
