Power up your remote‑control toys and LED lights with this 2‑pack 114065 4000mAh rechargeable Li‑Polymer battery set. Made with genuine Grade A lithium polymer cells, these batteries are perfect for RC electronic toys (remote‑control cars, trucks, boats, helicopters), LED lights (portable lamps, DIY lighting projects), and various 3.7V electronic applications. Each battery delivers factory‑rated 4000mAh capacity with built‑in protection against overcharge, over‑discharge, short circuit, and overcurrent — ensuring safe and reliable operation. The 114065 model is fully interchangeable with 124065 — both have the same 11×40×65mm dimensions.
Manufactured with high‑quality Grade A Li-Polymer cells and equipped with integrated PCM protection board. The protection features include overcharge protection (detection 4.25±0.05V), over‑discharge protection (detection 2.75±0.1V), overcurrent protection, and short circuit protection. With a cycle life of 500 cycles retaining 80% of original capacity and a service life of over 1000 cycles, these batteries offer exceptional long‑term durability. CE, RoHS, and UN38.3 certified for safe transport and use. Operating temperature range: charge 0‑45°C, discharge ‑20 to 60°C — suitable for outdoor RC vehicle use.
Compatibility Note: Fits devices that use 114065 or 124065 battery model with 2‑wire connection. No connector included — red and black wires only, ready for direct soldering. Please verify your device’s original battery model and connection polarity before ordering (red wire = positive “+”, black wire = negative “-“). Battery dimensions: 11mm thickness × 40mm width × 65mm length — measure your battery compartment to ensure proper fit. Suitable for DIY electronic products with power consumption less than 14.8Wh. Not suitable for high‑power power tools or drones.
Installation Tip: If your original battery has a connector (JST or similar), carefully cut and solder the plug from your old battery to these wires using heat shrink insulating sleeves to connect same color wires together (red to red, black to black). Always verify polarity before soldering and do not reverse the connection.
Battery Care Tips: Avoid full discharge — recharge when battery level drops below 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3‑5 full charge cycles to reach optimal capacity. Always use a compatible 3.7V Li‑Po charger with charging circuit protection (≤2000mA). Store in a cool, dry place when not in use.
