Compatibility
This 1S LiPo works with any device running 3.0â4.2V. Pair it with a TP4056 charging module for easy USB charging, or a boost converter for 5V Arduino projects. Common pairing with micro brushed flight controllers like BetaFPV or Eachine Tiny boards.
Wiring Notes
Connect red (+) to positive load, black (â) to ground via the JST plug. Do not short-circuit or discharge below 3.0V. Charge only with a 1S LiPo charger set to 0.5A max. Keep away from moisture and punctures.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino projects?
Yes, with a 3.3V or 5V boost converter. Use a TP4056 module for charging and a boost module to get stable 5V output for your Arduino board.
What charger should I use?
A 1S LiPo charger or a TP4056-based USB charger set to 500mA is ideal. Ensure it has overcharge protection at 4.2V.
Can I connect two in series for 7.4V?
Yes, two batteries in series give 7.4V nominal, but you must use a 2S balance charger and identical cells. Never mix aged or mismatched packs.
