Product overview
ChinaHobbyLine’s CNHL Racing Series 5200mAh 18.5V 5S 90C LiPo Battery with EC5 Plug is a rechargeable power pack for large RC sport planes, scale warbirds, helicopters and high-power RC vehicles. The softcase pack has five cells in a 5S configuration, a capacity of 5200mAh and a nominal voltage of 18.5V. It uses an EC5 power plug, a JST / XH balance connector and 10 AWG wiring. Stock number 520905EC5 identifies this configuration, which has rated discharge limits of 90C continuous and 180C burst; the burst rating has no specified duration or measurement conditions.
The pack measures 161 × 46 × 41 mm in length, width and height and weighs approximately 620g / 1.40lb. Installation requires compatible voltage, connector fitment and electronic speed controller specifications, along with adequate battery tray and canopy clearance. Aircraft must also accommodate the pack’s weight within their center-of-gravity range. Two matched 5S packs can be connected in series for a 10S installation in suitably configured larger RC warbirds or high-power aircraft. The maximum charge rate is 5C, and charging must stop when cell voltage reaches 4.2V per cell.
