When I try to order ku65 controller I found these New products - BMSBATTERY What is the key different between ku65? The big advantage I can see is it also accepts 48v for such small controller. Pat

I saw this from tech news and it seems to be great to electrify it :P Taga the ultimate alternative to Bike Trailer and Child Bike Seat Very practical idea. Hope they can sell it in UK Pat

Thanks Jeremy. If the KU65 is 50v capacitor, how easy to replace it with 63v one? Can you show me how to do it? I can do soldering.

Thanks Dave. Originally the plan was getting lipo but I am confident to handle them safely. That's why I need lifepo4 which saves me a lot of hassle. Do you know what is the capacitor inside the ku65? Thanks Pat

Hi all I am tempted to increase the top speed by replacing my 36v battery to 48v lifepo4 battery. My controller is ku65 but I am not sure if it can take 48v lifepo4 battery without blowing it. I remember the full charged 48v battery has around 52.4v not sure the capacitor in the...

Thanks Jerry. By the way, do you still recommend Tongxin motor? Is it pedelecs only? Can I add a throttle to it? For speed wise, I still want to maintain 16mph all the time during the ride. Ideally, it can achieve 15mph with throttle only. Pat

Hi there First, I am not an expert here but I have made my own conversion with the helps here The first conversion was Dahon Jack D7 2011 folding bike. I must say it is a perfect bike for conversion I am using SWXH motor 36v 12ah lifepo4 and it can go 18mph throttle only but I restricted it...

Thanks Morphix. Do BMS/GBK offer a sea freight option for shipping battery? I would not mind to wait a longer to save the shipping cost. p.s. you are very active here I wish you could electrify your D9 successfully. I have just done it my Dahon Jack D7 with SWXH motor and it is a perfect bike...

Hi again everyone I am a bit confused about the charging current for my 36v 12ah battery from BMSbattery. This is my battery 36V12Ah LiFePO4 Alloy 03-CASE EBike Battery With a Carrier Rack - BMSBATTERY the EMC-120 charger shows 42.6v for the charging voltage and this one below...

Hmm... I thought Fedex wont take the battery for shipping. DHL is the only option I suppose which is much more expensive Correct me if I am wrong.. Pat
