OZRC recommends following the conservative 5A manufacturer-listed current limit and the instructions provided by the compatible Smart charger unless Spektrum publishes revised guidance.\u003c\/p\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUse only a compatible Spektrum Smart charger with Smart G2 support\u003c\/li\u003e\n\u003cli\u003eConfirm the vehicle supports 4S LiPo power before installation\u003c\/li\u003e\n\u003cli\u003eCheck the 138 x 46 x 35mm battery dimensions against the vehicle battery tray\u003c\/li\u003e\n\u003cli\u003eNever charge a damaged, swollen or excessively hot LiPo battery\u003c\/li\u003e\n\u003cli\u003eCharge LiPo batteries in a suitable fire-resistant charging area and follow Spektrum's battery safety instructions\u003c\/li\u003e\n\u003cli\u003eSpektrum's current product page lists 55.5Wh, but 14.8V x 5Ah calculates to approximately 74Wh; verify the physical battery label where watt-hour information is required for transport or compliance purposes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- Listing structure follows the supplied OZRC Master Listings 2026 guide. Spektrum's current product page confirms SPMX54S100H5 as a 14.8V 5000mAh 4S 100C Smart G2 hardcase LiPo with IC5, 10AWG wiring, four cells, 138 x 46 x 35mm dimensions and approximately 520g weight. Spektrum also confirms single-connection balance charging, automatic storage discharge to 3.90V per cell after 72 hours, up to 1.5A storage discharge, internal metal side plates and IC5\/EC5 physical compatibility. Several older retailer feeds incorrectly reproduce three cells and 55.5Wh; current Spektrum data correctly identifies four cells, while the published 55.5Wh figure remains inconsistent with the nominal 14.8V and 5000mAh specification. --\u003e","brand":"Spektrum","offers":[{"title":"Default Title","offer_id":52856159732024,"sku":"SPMX54S100H5","price":279.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2849\/9768\/files\/Spektrum_Smart_G2_4S_5000mAh_100C_LiPo_Battery_IC5_SPMX54S100H5_2.png?v=1787734869","url":"https:\/\/ozrc.com.au\/products\/spektrum-smart-g2-4s-5000mah-100c-lipo-battery-ic5-spmx54s100h5","provider":"OZRC","version":"1.0","type":"link"}
