Is this normal voltage sag?
model: Teverun fighter Q
dual motors 500w each (peak 2500w)
battery 52v 13ah
problem:
when on gear 3 (max gear, speed limit unlocked), on ride, the battery sags from 40% to 18% (voltage sag 50v -> 48v). Riding speed was roughly 30-40 km/h.
I thought voltage sag only happens when scooter 'accelerates', not when the speed is fixed, but this gear keeps showing low battery/voltage level when on ride. The levels come back up (40% / 50v) when scooter stops.
The battery sag size (-22%) seems too big in my little expertise. Not sure if this can be normal for a 52v battery on max gear. The ride wasn't on a hill. Send help.
others to mention:
- only received the scooter 2weeks ago (so not much charge/discharge history)
- odometer 250 km
- rider weight 55 - 60kg
