Sanyo 16650 Raw Cell

The Sanyo 16650 battery measures approximately two millimeters shorter than the more popular 18650 size, which may the rechargeable power source suitable for use in more portable electronics, including some premium LED flashlights. This rechargeable Li-ion battery features a flat top and is designed specifically for use in battery packs. The raw cell is also a popular power source for TiB laser pointers; however, proper safety measures must be taken as it does not have a protection circuit to protect against short circuits and overcharging. Please make sure to familiarize yourself with the risks before proceeding at your own discretion. Please also note that the Sanyo 16650 battery requires a 4.35V charger in order to reach its full capacity of 2400mAh. This unprotected rechargeable cell is an affordable yet capable power source from a reliable brand.
