Re: Eco battery and cold(er) weather
With the huge sale they are offering this weekend I was already thinking there is a new battery line coming so they want to clear some inventory. I decided I no longer wanted the worry that the ET battery was causing so I went ahead with buying the 70v system. Hopefully it solves my problems and I can move on. That said, anyone in NC that wants a battery that works great in weather 60*F and above let me know

Re: Eco battery and cold(er) weather
I don't think that you'll be disappointed with that battery-congrats!! I also don't think you have to worry about it being obsolete :)

Re: Eco battery and cold(er) weather
My 72Ah 2nd generation Eco Battery is cutting off under full acceleration in the cold. About 20 degrees Fahrenheit. Stock 1510 controller and motor. Anyone have this problem or a way to address it?
Thanks! |

That said I’ve got allied instead of eco, but I’ve been out plenty in 15-20 degrees running it pretty hard in the snow and never had it cut out. So it’s either eco's BMS is configured differently, or some other external factor (SOC?) coming into play. |

If he doesnt want to check the setting its completely his choice of course but we have multiple threads more or less complaining of this issue now so you would think he would want to correct it or at least check it? |

you "should" be able to easily change these parameters within reason. the older extreme team batteries use the ANT bms and app which I actually have myself and it works the same way with the ant bms app. |

I would suspect that when you hit the go-peddle either your pack voltage, or more likely one specific cell drops below the LV cutoff setting. The "cure" is to have a full or near full charge before you venture out, and\or adjust your controller to allow less maximum amps to flow. All that does is conserve your pack voltage as the cart won't get the amps it's "demanding". |

Re: Eco battery and cold(er) weather
The thing that changes with temperature is the cell "internal resistance" which looks like a resistor in series with the battery. This resistance drops the battery voltage under load and the drop is a direct function of the battery current. In general, larger capacity batteries have a lower internal resistance. (if same chemistry) That is one reason I always recommend getting a larger (100Ah or more) pack even if you don't need the extra range.
