I bought for children's electric cars (two motors for 3000 revolutions - powerful in each), the child weighs 12 kg. In size, the 10x15 battery fits perfectly into a niche. The charge is enough for an average of 3 days of skiing for 1-1.5 hours a day (until the on-board electronics begin to report the need to charge the battery), while the car also continues to drive briskly. I didn’t try it until it was completely discharged, I suppose that it will pass with ease for another 3 days!
