When I have rang Mrs. K's doorbell, I found no one answer. I checked the map again to make sure the location and keep trying several times...Finally Mrs. K answered me. She said she was confused because her referrer told her GoodGym visit should be on Sunday instead. I understand her concern and worry, I show her the emails between mission control and me before she letting me in. It's easy to insert the extra battery to the wheelchair, however, only one cable connect to the motors. So, I read the user manual and the first sentence said "only one battery is used per time" & the 2nd battery is for backup in case the main one is drained during outing. Mrs. K said the dealer told her both batteries can be used at the same time that's why she willing to pay extra. Therefore, I suggested her to call the customer services and I keep checking out all the spare parts and cables provided from the packing. Then, I found a 3 heads cable which can connect both battery and to the motors. At the same time, Mrs. K received a installation video from the CS which is exactly the same I did. From now on, Mrs. K can move anywhere she want (including toilet she said 😉) during hospital visits instead seeking help.

Mrs. K said there are overgrowth tree branches which covering half of the car and it can't be used for long. So, I help to cut and remove those overgrowth branches before I left.
