18650 Li-Ion Battery (3.7V)

₹ 834.00
SKU ELC5030
Variety

These lithium ion batteries come in a variety of configurations and capacities. The battery with protection circuit provides over-voltage, under-voltage and over-current protection. Yet, it is slim and easy to fit into many project cases.

The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead at 2.5V. However, even with this protection it is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and at a rate of 0.5C (1 Amp) or less.


Additional safety notes: Do not use a NiMH/NiCad/lead-acid charger! Also, do not abuse these batteries, do not short, bend, crush or puncture. Never charge or use unattended. Always inspect batteries and surrounding circuitry constantly for any damage, loose wiring, or possibility of short circuits. Polarity matches all Adafruit LiPoly/LiIon chargers and boards, other brands may have reverse polarity and can destroy your battery. As with all Lithium ion polymer batteries and with any power source - they should be used by experts who are comfortable working with power supplies
