Seemed a bit expensive at first but is probably the most energy you can fit in a WLToys 12428 car, just need to move the battery tray side booms to outside of the tray area. Using 3S pretty much requires using metal rear gears (or low thrust EPA settings, OK for crawling or path running) but worth it; increased voltage allows more torque, the low battery limiter doesn't keep cutting off power at high load and ~30 Wh keeps the car running next to forever. The EC3 plug even fits XT60, which I am personally using, for a stock 12428 you'd need to change one of the connectors. Ordering more if/when I can, apparently there were some lithium battery transport policy changes again and delivery to my location wasn't available when I tried to order another. Now seems to be possible to order LiPos again, but this one out of stock.
