This is a drop-in replacement pack for the RFN Warrior Kids SX-E500, SX-E700 R and SX-E800 electric dirt bikes. It uses 30 grade-A 18650 cells in a 10S3P layout for 36V and 7.8Ah, about 280.8Wh, matching the stock 7.5Ah pack's energy so acceleration, top speed and runtime stay close to new. A built-in BMS covers overcharge, over-discharge, over-current, short circuit and thermal protection, and the XT60 connector handles the 500W–700W motors. It suits owners of these three Warrior models whose original pack is fading, and it fits the stock bay without brackets or adapters.
