    Regen/charging/Standard C-rating & voltage questions

    I see, gotcha So you are using your controller's discharge setting and LVC (both programmable I assume?) to limit the levels. A voltmeter is cheap and handy for sure Wouldn't "poking a hole to let the gas out" make the thing burst into flames? Not sure one can "poke a hole" in a pouch lipo...

    Regen/charging/Standard C-rating & voltage questions

    Sure, but what's the cost of A123 cells (if one can even find them easily) and the weight of lifepo4 vs lipo/li-ion packs and my scoot doesn't have the room for 20ah pouches regardless but I get your point...

    Regen/charging/Standard C-rating & voltage questions

    You're probably right, it's just a cost/numbers situation but in comparing prices it doesn't seem like more than a few bucks for to go from a 2a charger to a 3a or 4a and to charge in 2-3hrs vs 5-6hrs is a huge difference in my opinion if one uses it to commute or wants to recharge, say, while...

    Regen/charging/Standard C-rating & voltage questions

    I certainly don't trust the "200a or 300a" quote from HobbyKing (I used the same 20c 5ah 4s hardcase packs) but it sounds like they've held up for you for a long time so I don't know why I've had so many problems. And you aren't even using any bms with the packs? And if not, how are you...

    Regen/charging/Standard C-rating & voltage questions

    Forgive my questioning, but how did you know they are running at 30a peaks? Did you test with a standalone amp meter or some other reliable source? Just curious... Good question, but I did it several times and it could be a bad bms (from BatterySupports in China btw) and it wasn't all the packs...

    Regen/charging/Standard C-rating & voltage questions

    Interesting wesnewell What amount of amp discharge are you using either continuous or peak and for how long peak? Like I mentioned, for hill climbing I find 30a a good amount minimum to climb most hills for a few minutes at a time. Curious your experience if you've measured with a watt meter...

    Regen/charging/Standard C-rating & voltage questions

    Footloose, thx, so to follow your example then: 1) If I were to start with, say, a Samsung 3ah 18650 cell and string 4 in parallel for a 12ah pack total And were to use a 4a charger Then I would divide the 4a/4p = 1 and then divide 1 by capacity of cell which is 3ah so 1/3 = .33 So in this case...

    Regen/charging/Standard C-rating & voltage questions

    Hillhater, I agree they may be specific questions to some cells but in general have you seen a cell that charging at .5C would cause a problem? (and I don't mean some esoteric cell but rather the generally used decent discharge 18650 or pouch cells)? And this may be a dumb question but I've...

    Regen/charging/Standard C-rating & voltage questions

    Thx and just curious wesnewell, where you get the info you mentioned for #1 (and #5) I believe I have heard its .5C for charge rates as well but not sure if that's common practice or just a quote from a battery spec page somewhere. I know there is what they say to do and then there is what one...

    Regen/charging/Standard C-rating & voltage questions

    Couple general questions for all: 1) What is the basic recommended charging speed for, say, Samsung 18650 3ah cells? If they were in a 4p config at 12ah, could one safely charge them with a 3a charger? Is .5C or 1C a standard for best practices charging for decent cycle life? How far could one...

    That's good it arrived but too bad you don't like/ride it Their comment page on indiegogo seems full of complaints on the quality/hardware/frame etc and some hadn't received yet so I was curious as you seemed very gung ho for this product considering now you don't even ride it at all... I...

    Bestechpower BMS

    I'm using a generic brand from china among others and they all seem similar in construction. Others have mentioned that unless I rode it downhill for 10 minutes straight (rarely have hills that long even at slow speed) it wouldn't have the over-regen charging issue although it seems several...

    Bestechpower BMS

    What happens when regen ebraking down a hill after a full charge is it just won't brake (cuts off regen) and the mechanical brake is my only brake but that's plenty, so not worried there about lack of brakes but more worried about over-charging at 15a using the regen going back into the battery...

    BMS & regen braking/ discharging question re 18650 cells

    Question for anyone with knowledge of bms/charger/regen capable controller - I have a generic controller with regen braking using 12s 10ah Samsung cylindrical cells and was told that the amps being put back into the battery are slightly high for a 12s setup using this particular controller and...

    Question for you Dnmun or anyone with knowledge of bms/charger/regen capable controller - I have a generic controller with regen braking and was told that the amps being put back into the battery are slightly high for a 12s setup and is meant for a 15s (the controller's regen) but I wondered...

    Wouldn't call it miles, in fact I'd say they're in the same class and only one exists currently, it has no suspension (and trust me, ride a razor and then ride a full suspension on 8" tires and you will totally see the difference) and is virtually the same weight (5 lbs less without suspension)...

    They're going to a lot of trouble to fool people if they claim August delivery from the start which is ambitious and from judging by all the piles of manufactured parts pics they've posted, looks good for ya I'm thinking, and doesn't strike me as shady. Seems like they're making massive progress...

    List of available commercial mini E-Scooters/E-Skateboards

    First, the Vomo is heavy and doesn't have many features at all, especially compared to the EcoReco (the Vomo 'stole'/copied their folding handlebars exactly) and yet doesn't have front or rear suspension which is a must for higher speeds on small tires especially solid/airless tires like the...
