Displays for 58-60V battery

[Palm]

Hi. I am new in this forum and the magnificient world of e-biking. It's the ultimate hobby.

My first newbie bike has a 1000w hub motor chinese conversion kit with 48V dolphin pack and a KT LCD3 display.

I am planning to try with a 58V lipo battery and a new 35A controller. Have been searching here and the web if the KT LCD3 display will handle this - does anybody know? Have only seen that it is compatible with 36 and 48V.

If not - tips to which displays that may work well with this Voltage?
Thx.

A fully charged "48V" battery, if it is 14s LiPo/etc would be around 58v or so anyway.

So if you already have a 14s pack, you may already be at that voltage.


But ifyou havea "60v" battery, then fully charged it could be more than 66V (it's probably a 16s pack).

I currently have a 48v Dolphin pack that is 53-54 volt fully charged, according to the display's meter.
I'm planning to swap with a 8S+8S Lipo in series, that should give me 59,2v (nominal I assume).

Question is if this Lipo pack would work ok with display or kill it?

Is the new controller compatible with the KT LCD3 display? I haven't used the kit that comes with that display, but like dogman said it should be ok at 14s. I don't think they are designed for much more than 60v, so at 16s (67.2v fully charged) it will probably get destroyed or go into protection mode if it has high voltage protection. The Cycle Analyst is a much more comprehensive and versatile display if you have a little extra cash to spend on it..

Do the basic (40-50 usd on aliexpress) controllers out there need to be configured for each specific display? I see many take the most standard signal voltages from throttle, pas etc - would assume that there was some kind of standard for the signals used between components (with some exceptions naturally).

Your display is limited to a max of 60V, so if your battery pack charges over that, and a 16s pack would charge to 67.2V, your system won't run. That would also put the voltage to the controller over the 63V spec limit and likely cause it to fail. For 16s, you really need a 60V controller. but at that point you might as well go to 20S and get a 72V controller. They sell display compatible 72v controllers, but you'd also need the new display.

Thanks for great answers.

I measured the new 8s 12000mah multistar batteries between 33,3- 33,5 V, charged the first time with a balanced charger. Will take them below 30V and test it. Am anyway going for the CA v3, but waiting is hard so I'll see what the lcd3 can handle.

Thx

The display won't work with another controller that isn't a KT unless it has the correct connector, the same data protocols and compatible software.
