I got a wolf warrior x in August last year and it is awesome. However, some problems has been occurring starting last month. At full charge it’s at top performance but at about 60% charge, the top speed, acceleration and hill climbing starts to get bad by a lot. At about 30% charge, top speed is only 20mph at dual motor and it just keeps giving the “low voltage” warning. When I charge it back to full no problem but the cycle happens again. No it’s not because of cold weather I live in the south. Please help thanks.
