Yes I regret a little I didnt buy 20ah. Maybe Ill try to expand parallell. And yes better unload and go twice. Even the rims or something else could brake. I also have yet to install ampere/volt instrument. Its almost Connected after 4 years haha.

Bought two 13S4P = 48V13.5Ah (650Wh) = ca 2900 gram = ca 70*300*90 mm. Hill climb with 125 kilo concrete but had alot force on the pedal aswell.

How is my current setup compared to if I would buy another battery, 26 amp hour. Bms rated 35 amps 1500 watt. Could I connect my 13.5 in parallell each with same bms 35 amps 1500 watts. This would mean two bms on one motor and one bms on the other. Anyone elaborate on this? I usually ride...

I was considering more AH but the retailer specify all their 48V Batteripack on max 35A/1500W. I usually dont ride too far.

Update. Bought two 13S4P = 48V13.5Ah (650Wh) = ca 2900 gram = ca 70*300*90 mm. Works Great. Thanks all. I now have some extra power in my steep hills

Borrowed friends display. Wasnt cables. Now both work 😀

Should I buy new controller and cables and display? Any advice on what to buy?

Got new display. It said 36v on the bottom. I tried anyway. Led was on for one second. Now dead. There are cables between the display and controller. Took some photos and attached. Guess the cables could be faulty somehow. The controller and motor still works if I change.

Ok thanks! Reason why I need torque at lower speed is that I travel short but have very steep hills. Its a cargo bike with hub in each front wheel. I prefer climbing the hills slow. I normally use little throttle. More throttle doesnt help. I have to assist a little on the pedal when unloaded...

I guess I cant change the amps without new controller and then there is risk of broken motor? Im considering batteries like Two 48v10ah litium. One for each motor. Or One 48v litium for both. Not sure on how much ah I need and if I should look for anything more in the specification. Or Four...

Great response! Heres photo of controller:

Hello, I have two 1000 watt hub motors on four 12v 12ah SLA lead acid batteriets. Can this limit the torque somehow? Their good but I need all torque i can get.

The seller www.rull.se responded "good you found the problem. Buy new controller from this shop: https://www.evobike.se/5-speed_PAS-kontrollpanel_till_Evobike

Good point :thumb: Ill try. And I got 2 hubmotors on the bike. When I switch the cables between them the motor and box works fine. Maybe display is faulty...

Hello! I was out biking and my motor suddenly went offline. When i press the ON button the led briefly lights up. If I press and hold the On button I am able to run the bike. It also stops when I let go of the ON button. Any advice?
