3.7V LiPo Battery with JST ACH 1.2mm Connector Power your wireless builds without the hassle of crimping or soldering. This 3.7V Lithium Polymer (LiPo) battery comes pre-terminated with a JST ACH 1.2mm pitch connector, specifically chosen to be a direct plug-and-play match for the Wireless Corne SMT and Rechtech products. The Perfect Fit Most standard LiPo batteries ship with JST-PH 2.0mm connectors that are too large for ultra-compact wireless splits. We sourced these batteries specifically to eliminate that problem. They mate perfectly with the BM02B-ACHSS-GAN-ETF headers used on our wireless PCBs, ensuring a secure, low-profile connection that fits inside even the slimmest cases. Compatibility This battery is the official power source for the Boardsource wireless ecosystem but is compatible with any project requiring a 3.7V cell and an ACH connector. Wireless Corne SMT: Fits perfectly in the central battery cutout. Rechtech: The official replacement battery. Safety & Specs Voltage: 3.7V Nominal Connector: JST ACH (1.2mm Pitch) Protection: Integrated PCM (Protection Circuit Module) to prevent overcharging and over-discharging.
