1 / 1Cogalloy 7.4 V 2200 mAh 10C Protected Robot Battery Pack
A compact 69 × 37 × 19 mm, 7.4 V 2200 mAh 10C protected rechargeable lithium battery pack for compatible robot power systems. It has DC 5.5 × 2.5 mm female and SM-2P male connectors; use only the verified 8.4 V charging path. Battery pack only unless the order explicitly adds a charger.
- 69 × 37 × 19 mm protected robot pack: A compact 7.4 V, 2200 mAh battery form factor for compatible mobile-robot bays and 7.4 V power paths.
- Two connector paths—verify both: DC 5.5 × 2.5 mm female and SM-2P male connectors are supplied on the pack; confirm polarity and the actual harness before power-up.
- Protection board is part of the pack: Supplier documentation states overcharge, over-current, over-discharge and short-circuit safeguards; never bypass them.
- Runtime is a whole-robot result: 16.3 Wh nominal energy and a 60-minute reference do not replace a load, thermal and voltage-sag test on the finished robot.

FORM FACTOR AND CONNECTION
Start with the actual pack, not a generic black battery box.
This pack is 69 × 37 × 19 mm, labelled 7.4 V / 2200 mAh / 10C, and has DC 5.5 × 2.5 mm female plus SM-2P male connections. Use the physical dimensions, delivered cable and robot-side pinout together before ordering or assembly.
- Nominal system voltage: 7.4 V
- Capacity: 2200 mAh / nominal energy about 16.3 Wh
- Do not decide polarity from connector shape alone
CURRENT AND PROTECTION
Treat 10C as a system-integration input, not a blanket current promise.
The supplier specifies a 10C pack label and an integrated protection board. The useful current in a robot is constrained by the protection path, connectors, cable gauge, controller, motor peaks and temperature. Design and validate the complete chain.
- Supplier-stated safeguards: overcharge, over-current, over-discharge and short circuit
- Never bypass the protection board or short pack contacts
- Check voltage sag during starts, acceleration and stall-prone tasks


CHARGING DISCIPLINE
Use an exact 8.4 V charging path—and do not guess compatibility.
The documented matched charger is 8.4 V. Charger, cable and adaptor are not assumed in the base battery SKU, even when shown in the reference image. Confirm output voltage, connector, polarity and the delivered instructions before charging.
- Charge on a stable, non-flammable surface under suitable supervision
- Disconnect after charging and let the pack cool after charge or heavy use
- Stop using the pack if it is damaged, swollen, leaking or abnormally hot
MOBILE-ROBOT REALITY
Measure runtime where the robot actually works.
The supplier cites up to 60 minutes in matching robot configurations. Terrain, payload, driving, motor peak current, sensors, host compute and temperature can change that result substantially, so use a representative mission test before deployment.
- Match only a verified 7.4 V robot input path
- Do not substitute 5 V USB power, 11.1 V/3S packs or an unknown lithium charger
- Check carrier restrictions before shipping a spare battery to the destination

Overview
A protected 7.4 V battery pack for matched robot power paths
Cogalloy COG-7V4-2200-LIPO is a compact 7.4 V, 2200 mAh, 10C protected rechargeable lithium battery pack for the 7.4 V mobile-robot power systems used by matching Cogalloy T1- and Cogalloy L1-style builds. It measures 69 × 37 × 19 mm and provides a DC 5.5 × 2.5 mm female connector plus an SM-2P male connector. Confirm both the mechanical fit and the delivered harness before connection.
The base SKU is the battery pack. The pictured 8.4 V charger is the matched charging reference, not an inclusion promise: charger, cable and robot-side adaptor are included only when the final order line explicitly lists them.
Match voltage, connector and charger as one system
7.4 V is the nominal battery-system voltage; use only the exact compatible 8.4 V charger and the intended connector path. Do not substitute a USB supply, 5 V adapter, 11.1 V/3S pack, an unknown lithium charger, or a mechanically similar plug. Check polarity at the robot-side harness before first power-up—connector appearance alone is not a polarity guarantee.
The 10C marking is a pack label, not permission to assume every connected system can continuously draw 22 A. The protection board, connector, wiring, controller input, motor load and temperature together define the usable current. Size the whole robot for motor-start and stall peaks, and protect the host computer and sensors against voltage sag.
Protection, use and care
Supplier documentation describes high-quality 18650 cells and an integrated protection board for overcharge, over-current, over-discharge and short-circuit protection. These safeguards reduce risk but do not make misuse safe. Never bypass the protection path, short contacts, puncture, crush, disassemble, expose to water or heat, or continue to use a damaged, swollen, leaking or abnormally hot pack.
Charge on a stable, non-flammable surface under suitable supervision, disconnect after charging, and allow the pack to cool after a high-load run or charge before handling/packing. Keep terminals protected from conductive objects during storage and transport. Battery shipping, service and replacement availability depend on the destination and carrier; no transport certification is implied by this listing.
Runtime and product identity
Nominal stored energy is about 16.3 Wh (7.4 V × 2.2 Ah). In matching complete robot configurations, the supplier cites up to 60 minutes; driving style, terrain, payload, motor peaks, sensors, compute load, temperature and pack condition determine the real result. The supplier labels this product a LiPo battery while its product description refers to 18650 cells. For safe selection, this listing treats it as a protected rechargeable lithium battery pack and relies on the delivered pack label and documentation for chemistry-specific handling.

Frequently asked questions
Is the charger included with this battery SKU?
The base price is for the battery pack. The 8.4 V charger in the image is a matched charging reference. Include it only when the final order line explicitly lists the charging set, cable or adaptor.
Which charger may I use?
Use only the exact compatible 8.4 V charger after confirming connector, polarity and the delivered instructions. Do not use a USB supply, 5 V adapter, unknown lithium charger or a charger selected only because its plug appears to fit.
What do the two connectors do?
The pack is specified with a DC 5.5 × 2.5 mm female connector and an SM-2P male connector. Their use depends on the matched robot and charging harness; inspect the delivered wiring and verify polarity before connection.
Does 10C mean I can draw 22 A continuously?
No universal continuous-current guarantee is made from the 10C label alone. Protection-board limits, connectors, wiring, controller input, motor load and temperature all matter. Validate the complete robot power path, especially motor starts and stalls.
How long will a robot run?
The supplier cites up to 60 minutes in selected complete robot configurations. Driving, terrain, payload, motor peaks, sensors, compute load, temperature and battery condition can shorten or extend the real result, so test the completed robot.
Is this a LiPo pouch pack or an 18650 lithium-ion pack?
The supplier's pack label calls it LiPo, while the supplier's product description refers to 18650 cells. This listing therefore describes it as a protected rechargeable lithium battery pack. Use the delivered pack label and documentation—not the SKU name alone—when selecting chemistry-specific handling, charging or transport procedures.
Can it be shipped to every destination?
No. Carrier, destination and service restrictions can apply to lithium batteries. Confirm transport eligibility and any required documents before ordering a spare or arranging onward shipment.
