Lithium Ion Polymer Battery with Short Cable - 3.7V 420mAh
We have ✅ 3 available of the AF-4236 in our Sydney warehouse.
A 3.7 V lithium-ion polymer (LiPo) battery with 420 mAh capacity (approximately 1.55 Wh). It features a short cable with a genuine 2-pin JST-PH connector that clicks smoothly into matching JST jacks without snagging.
The battery includes built-in protection circuitry that guards against overcharging, over-discharging (cuts off at 3.0 V), and output short circuits. Output voltage ranges from 4.2 V when fully charged to 3.7 V nominal.

Warning: Only use a LiIon/LiPo constant-voltage/constant-current charger at 420 mA or less. Do not use NiMH, NiCad, or lead-acid chargers. Do not short, bend, crush, or puncture. Never charge or use unattended. Always inspect batteries and surrounding circuitry for damage, loose wiring, or short circuits. When using conductive thread in wearable projects, take extra care to avoid shorts which can create sparks and heat.
