My battery display typically fills up to the minus sign in the picture, with the top area left empty.

Due to the desighn the system will never show 100% full or less than 1/4 empty. this is for maximum battery life of 8-15 years on the traction. full charge or full discharge would be early retirement for this battery.

Re: 12 Volt Battery

The top area of your battery display is the 20% left for braking. Braking down a 16% mountain or using the brake position on the selector. I have found using the braking selection works better at slower speeds like 35 mph or slower. It in many cases it adds in the brakes which adds wear if you going faster.
