I bought my used SC TS lite late December and while browsing this forum i saw the Y Cable and dual battery modding and i had the shop that sold me the bike mod it for me. The Y Cable was RMB 250 (used) and the second battery RMB 2000 (also used). Since then i have been using this modded setup and beside a few quirks it has been running flawlessly. I get error 94 on the display sometimes but the bike runs well anyway, i have some throttle lag sometimes but not that often. I mostly charge the bike in the garage and i haven´t taken the batteries out since then, i use the charging port on the side of the bike. My daily commute is 8 km one way, takes me about 15 minutes in gear 3 at 60 km\h. Daily i do about 24 km in total, so i charge the bike 3 times a week from about 15% to 95% with a 6 to 9 hours with a charger timer. 

In my commute sometimes i feel that in traffic i would need the bike to be a bit faster because i commute on the ring road and if the bike could reach 70 km\h it would be perfect.I would like to ask the community if there's anything i can do to achieve that goal.

I would like to keep the look of the bike as close to the original as possible, to keep it low key specially for the traffic police 😉

Here are the photos of the modding:

In May i had my birthday so i decided to treat myself to one new mod, new brake levers and 2 new tires.

I changed my bike ECU and HUB from the TS Lite (1200 Watt) to the TS PRO (1500 Watt).

I've heard the parallel box is not good for your batteries, is it doesn't share the load in parallel, but just shifts the load back and forth. *note* I don't have evidence. This is just based on conversation. 

To get the boost in speed, having two batteries should help, less voltage sag. But next would possibly be a new controller, unless you know of someone who can reprogram the OEM. Puntofato has used the Kelly controller but recommends the Sabvoton with flux weakening for top speed.

@sdreaver The parallel box does have a system so the batteries are in parallel. Otherwise it would indeed be bad for the batteries.

@sdreaver I have been riding the bike daily and my batteries drain within 3% difference from each other. So if i start my day with 100% on both batteries and i ride from home to work and back i arrive home with 75% in one battery and 77% on the other. Because i ride mostly in a ring road here i keep the bike in sport mode and most of the way i´m going at 50 ~70 km/h. The top speed is 75 km/h but it´s really hard to achieve that speed. The normal top speed is around 65 ~68 km/h. I have now more than 9000 km on the bike (not all made by me since i bought it second hand) i would say i already put in around 4000 myself in about 6 months. I ride it everywhere and i´m very happy with all the upgrades and changes i made to the bike.
