    Is Generic Lithium Charger overcharging LiFePO4 Battery?

    Conventional wisdom states that Lithium Iron Phosphate cells should not be charged over 3.65V per cell. However, the 3A Chinese battery chargers that came with my LiFePO4 batteries charge my 36v 10Ah batteries to 3.71V per cell. It is a generic lithium battery charger, not specific to LiFePO4...

    Calling All Experts->Unsolved Mystery: Sudden Battery Voltage drop to Empty

    Well one of the two motors that Justin sold me has always made a weird sound everytime after it warms up a little, and I have had a problem with the two motors not putting out equal power always since the beginning of this new getup in 2018, much to my annoyance (veers slightly to the left)...

    Calling All Experts->Unsolved Mystery: Sudden Battery Voltage drop to Empty

    on the first comment re:bms, please elaborate. in regards to the motor cable suggestion, if this were the case, why did the system work fine with my back up pair? Additionally, even 5 days later after the failed set had been recharged, the Phaserunners still 'recognized' these batteries...

    Calling All Experts->Unsolved Mystery: Sudden Battery Voltage drop to Empty

    joneyjoe303, It is quite possible that my cheap Chinese chargers are not doing what's optimal. I DO have a single Cycle Satiator and could be individually topping off and balancing packs to a custom maximum. I have not yet broken into the pack to see if the cells are currently balanced...

    Calling All Experts->Unsolved Mystery: Sudden Battery Voltage drop to Empty

    Okay, I've got the puzzle for you! I"m an experienced e-trike builder, been doing it since 2006. I keep a detailed log so buckle up. Current set-up: one power main goes to 2 Phaserunner motor controllers to 2 hub motors. I generally run off of a pair of LiFEPO4 bricks at one time. They run...

    Wind and Solar vs Coal, Gasoline, Nuclear

    I see a lot of talk about self-driving cars here. There's an awful lot of positive 'spin' on the IOT but I think we can agree here in this ebike forum tjat simply using LESS energy solves an awful lot of problems. How many of you have considered the energy cost of the IOT (especially...

    How to wire a key switch properly? (for main power)

    TommyCat, yeah I saw that item on a similarly-themed thread. People complained about it not being weatherproof, but that sounds like a not-insurmountable problem. Thanks for explaining what the little wires do. If the remote switch I just installed fails (or i lose the only remote {: o ), that...

    How to wire a key switch properly? (for main power)

    In case anyone is interested, LockMasters just pointed me in the direction of a different Pollak switch than I was already aware of, 31-499, which is the same size as a standard automotive switch but rated to 40A continuous! That's beefy, folks. If you have a large enough vehicle to care...

    How to wire a key switch properly? (for main power)

    fechter, I have two controllers and they are hard to reach. Some have switches so one wouldn't even need to unplug them. I also don't store it for a long time, I drive it nearly every day. But yes, all advice would be appropriate to a less complicated set-up

    How to wire a key switch properly? (for main power)

    amberwolf, as you can tell, I clearly have no idea how to do this forum thing correctly! { :D I have seen those isolater switches everywhere, but I'm designing a product, not just a one-off, so I can't imagine this sort of a clunky generic key being a selling point for future buyers. If...

    How to wire a key switch properly? (for main power)

    Which cutoff switch are you using from Harbor Freight? Just curious. And what are you running at? What's your top Amps output? The 'solenoids' I have been looking at have 4 connectors. I actually think I DO need what golf carts are using. And the run of the mill ones are actually not so big...

    How to wire a key switch properly? (for main power)

    amberwolf Oh my goodness, I didn't remember posting before, and about the same problem, and now there are so many wonderful replies to that thread which I will now review! When I wrote 'most switches', I mean't 'most automotive and scooter key switches.' I see a few on the market that are 24V...

    How to wire a key switch properly? (for main power)

    Hey there! This is actually my first time posting! I build Electric-Assist Tricycles. They currently draw up to 50A continuous at 36V. I have been using automotive switches (and before that, e-scooter switches) for my 'frankentrikes' (www.frankentrikes.com). My current rated 12V 35A...

    California: AB-1096 to classify an "electric bicycle"

    Is there ANYONE ELSE on this list that would like to see an elimination of the max. wattage requirement from the bill wording? 750W does NOT move my electric-assist tricycle; it weighs over 200lbs! It is not a racecar and does not even accelerate as fast as a car and the assist still tops out...

    Key Switch for E-Bike

    Bill, just wondering how that switch fared for you, after 2 years of use. I have burned out more than one 30A+ switch myself, but I am running up to 1600W on my cargotrike (at 36V), so maybe it isn't an equal comparison. Still, wondering how it fared, since they are rated for 12V and you...
