I agree, my controller didn't come with those 2 wires because I had an early version. But there are instructions showing how to do this modification. I should do this as an extra safety.mudale222 wrote:U should physically turn off ur ebike every time u get off them. This is the safe thing to do regardless of voltage drop. Any vehicle that not in immediate use should be turn off. I have small nephew (maybe 6 years old) who fully switched the throttle in the middle of the house.. It's flew like a rocket into the refrigerator... Easily could be a disaster.
In the adaptto u have two wires to make a switch. Use it.
Odd, you must have had it turn on or it didn't enter suspend mode like mine.ridethelightning wrote:
I had this exact thing happen with 2 adaptto bikes, after leaving for ~3 months.
normally they dont lose any charge even when sitting for several weeks, but i got back to find one 2kwh and 3kwh ,22s packs at 10v and 26v respectively.
not sure what happened. the dc/dc was disconnected so not that, i think it may be suspend mode not working but who knows!
-always turn your bike off or disconnect battery for any length of storage!
I also had my DC -DC connector switched off, I had no other load on the battery.
Thats my worst nightmare coming back and finding a huge pack like ours at low voltage like that. I already had this happen to a 2KW lipo pack, but it dropped to around 2.5 volt per cell and seemed fine after charging it. I had my DC-DC converters hooked at the time, but they don't draw much power in standby so I usually just left them on.
What we have learned is that just because the controller doesn't seem to draw much power, there may be conditions where it may draw extra power beyond our control so we have to assume this could happen at any time.
