    Battery indicator shows empty after short distance

    The display and controller are both dual voltage 36/48v. The motor is 36v and the battery 48v. As you previously suggested, I plan to dabble with P5 over the next few days. I was extremely careful making all the connections, as it's the first time I've ventured into anything like this, but think...

    Battery indicator shows empty after short distance

    I took the initial reading with my DVM. When the display gave an identical reading, I assumed that it was functioning correctly, so the end reading was just from the display.

    Battery indicator shows empty after short distance

    Yes - it appeared ok, but separated it and re-seated just to be sure.

    Battery indicator shows empty after short distance

    Yes, it does for a while after I stop, then goes back to showing full (ie, all bars reappear). The battery LEDs still show full.

    Battery indicator shows empty after short distance

    It wasn't cutting out - I was just concerned about the (apparent) extremely rapid depletion of the battery. I have mobility problems and will be dependent upon the electric assist on longer rides. I particularly need to know when to head home whilst still having more than half battery capacity...

    Battery indicator shows empty after short distance

    Thanks vfr. The bullet connections on the battery were incompatible (different diameter) with the ones on the controller, so I soldered extensions to the controller wires (correct gauge) and fitted an Anderson Connector.

    Battery indicator shows empty after short distance

    Thanks Nealh. What readings would indicate a saggy battery? (The voltage was fairly constant during my ride, just dipping briefly on a short, steep slope).

    Battery indicator shows empty after short distance

    Ok, Just fitted in another test ride. P5 is set to 12. Starting voltage (after top-up charging the battery) was 53.6v on the display, confirmed with my voltmeter. Rode for around 1 mile on flat and gentle incline, using level 2 assist. The battery level indicator on the top of the display was...

    Battery indicator shows empty after short distance

    Thanks for the advice, all. I hope to test it tomorrow (rain permitting) and let you know the outcome.

    Battery indicator shows empty after short distance

    No, the battery is new and was delivered charged. I've just given it a couple of brief top-ups with the only charger I have - a standard 2A charger Eclipse supplied with the battery.

    Battery indicator shows empty after short distance

    I'll check tomorrow and let you know - thanks

    Battery indicator shows empty after short distance

    Yes, thanks - I'll try another run tomorrow, then check the voltage. Am I correct in thinking it should be around 52v?

    Battery indicator shows empty after short distance

    It shows empty for a while after the motor has stopped, but when I return later and switch it on again, the battery level on the display shows full once more.

    Battery indicator shows empty after short distance

    Well, at long, long, last I finally had free time to 'electrify' my trike. I'd like to offer a huge 'Thank You' for all the invaluable advice given to me by members of this forum in getting to this point. I've now been for a couple of inaugural shake-down rides (a mile at most), and on both...

    Controller cooling

    Thanks vfr. The Q128 is nominally rated at 201 rpm, although I believe 260 rpm is the actual maximum, and possibly higher, I guess, as I'm using 48v for a 36v motor. Until I have the rig up and running, I don't know how much I'll use level 5. I anticipate that it will rarely be needed as it's...

    Controller cooling

    After many months of other demands on my time, I'm finally back to installing my trike motor. I plan to mount the controller on an aluminum plate below the carrying rack (yes, there is enough clearance for suspension travel!). I intend to buy a small IP-rated enclosure to protect the bunch of...

    OK to extend PAS cable?

    Thanks AK. I'll see how it goes at my tame pace, but may end up relocating to below/alongside the seat.

    OK to extend PAS cable?

    Following advice/reassurance from Woosh & Nealh, I intend to extend the PAS cable. I plan to cut an aluminium plate which I will bolt below the pannier rack (on the rails parallel to and below the top rail), ensuring there remains adequate clearance at full suspension deflection! The controller...

    OK to extend PAS cable?

    At long, long last I have started installing the kit on my recumbent trike. I want to position the controller in a spot where it is least likely to get splashed by water thrown up from the wheels whilst retaining a good airflow over (which I assume it needs, given the cooling fins). However, the...

    Bunch of ebike stuff from BMS battery

    I don't think you can edit titles (poor choice of words on my part). Probably best to delete the posting (if possible) and/or create a new one. Good luck with selling.
