Which Devices Are Compatible with the Tenergy 11.1V 5200mAh Battery?

This battery powers RC cars, drones, airsoft guns, LED lighting systems, and portable medical devices. Its compact size (138 x 43 x 24mm) fits most standard compartments. Verify voltage and connector compatibility before use. Avoid pairing with devices exceeding 20C continuous discharge rates to prevent overheating or damage.

Extended compatibility includes specific models like the Traxxas Slash 4×4, DJI Phantom 3 drones, and airsoft replicas requiring sustained power output. The battery’s JST-XH connector works with popular balance chargers such as the SkyRC T200. For LED applications, it supports 12V systems when used with step-down converters. Always confirm polarity alignment when connecting to custom setups to avoid reverse-charge incidents.

How Does the Tenergy 31033 Compare to Other LiPo and Li-ion Batteries?

Unlike LiPo batteries, the Tenergy 31033 uses Li-ion cells, offering higher energy density and slower self-discharge (3% monthly vs. 5–15% for LiPo). It’s lighter than NiMH alternatives but has stricter voltage limits. While LiPo batteries support higher burst rates, the 31033 excels in longevity and thermal stability for moderate-drain applications.

Feature	Tenergy 31033	Standard LiPo	NiMH
Energy Density	250 Wh/kg	200 Wh/kg	100 Wh/kg
Self-Discharge	3%/month	5-15%/month	20%/month
Cycle Life	500	300	400

The Tenergy 31033’s thermal management outperforms many LiPo packs in scenarios where consistent mid-range power is required. For example, in RC boats operating at 50% throttle for extended periods, it maintains cell temperatures 10-15°C lower than equivalent LiPo batteries. However, competitive drone racers might still prefer LiPo for its 75C+ burst capabilities during sharp maneuvers.

FAQ

Can the Tenergy 31033 Be Used in Parallel/Series Configurations?

Yes, but only with identical batteries of the same age/cycle count. Parallel setups increase capacity; series configurations boost voltage. Use a professional battery management system (BMS) for multi-pack arrays.

Does the Battery Include a Low-Voltage Alarm?

No. Users must employ external voltage alarms or telemetry systems to monitor discharge levels during operation.

Is the Tenergy 31033 Airline-Approved for Travel?

Lithium-ion batteries under 100Wh (like the 31033 at 57.72Wh) are generally permitted in carry-ons. Check airline policies and declare the battery during security screening. Tape terminals and pack in fireproof containers.

“The Tenergy 31033 bridges the gap between hobbyist and industrial-grade batteries. Its hybrid design optimizes energy density without sacrificing thermal management—a rare feat in mid-priced Li-ion systems. For users prioritizing cycle life over extreme discharge rates, it’s a game-changer.” — Dr. Elena Torres, Power Systems Engineer
