Rechargeable Hot Selling Lithium-ion Battery LP21700B 4500mAh with Connector JST PHR-2

Lithium-Ion Battery also named Li-ion Battery, it’s a rechargeable battery, high energy density, and costs less.

LiPol Manufacturer Supply kinds of Rechargeable lithium-ion batteries, such as Lithium-Ion Battery LP18650(diameter 18mm, length 65mm), Lithium-Ion Battery LP26650(diameter 26mm, length 65mm), Lithium-Ion Battery LP21700(diameter 21mm, length 70mm).

This Lithium-ion battery has a capacity of 4500mAh for a total of about 16.65Wh. If you need Others Lithium-ion Batteries, we also have other Lithium-ion Batteries.

Also we have others capacity of Li-ion Batteries

Also, you can choose the connector that you need to add with the battery, The connectors we use are mainly from three famous brands” Molex”, “JST” and “Hirose”. All battery connectors from Molex or JST are available to add to our lipo battery with the custom length of wires, wire sequence & wire colors. You can browse the following page to select the connectors you want.

Choose the suitable battery connector for your LiPo Battery

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 3.0V. It will also protect against output shorts. 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 or less.

Like most LiPo batteries we sell do not have thermistors built-in. This is why we suggest charging at 1/2C or even less in this case which is how much you can get from a USB port.

Additional safety notes: Do not use a NiMH/NiCad/lead-acid charger! Also, do not abuse these LiPo batteries, do not short, bend, crush or puncture. Never charge or use unattended. Always inspect LiPo batteries and surrounding circuitry constantly for any damage, loose wiring, or the 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 LiPo batteries and with any power source – they should be used by experts who are comfortable working with power supplies.
