li-ion 7.4v 2000mah lithium battery Discriptions:
Search a 7.4v 2000mah battery? This 7.4v 2000mah lithium battery is made of 2 balanced 2000mAh cells for a total of 2000mA capacity! The cells are connected in series and spot-welded to a protection circuit that provides over-voltage, under-voltage and over-current protection.
Each cell can provide 0.5C of current (1 ampere) so all together the peak current you can draw is over 1 Amps. Note that these batteries are not designed to sustain such high loads, we suggest keeping any constant current draw under 0.2C or 1A.
7.4v 2000mah li-ion come with color coded wires, and with a JST 2-pin cable attached for use with chargers! Because they have a genuine JST connector, not a knock-off, the cable wont snag or get stuck in a matching JST jack, they click in and out smoothly. The cables are rated for 1A so if you use them keep that in mind.
The included protection circuitry keeps the 7.4v 2000mah li-ion battery pack voltage from going too high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead at about 6.0V. 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 0.25C (500mA) or less.
The 7.4v 2000mah lithium battery we sell do not have thermistors built in(optional). This is why we suggest charging at 0.2C or even less – 500mA max in this case. Of course, you can charge at a lower rate – it’ll just take a little longer to fill up.
Additional safety notes: Do not use a NiMH/NiCad/lead-acid charger for the 7.4v 2000mah battery! 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
