    I live in North Dakota and i will have to test a lithium batteries in my car and semi truck next winter. You should do a video about what happens when lead batteries try to give/receive charge

    May I charge the big li-ion battery of my ebike in my apartment and then store it on the balcony for the night, even if the temperature in winter can go down to -5 Celsius?
    I will have performance issues the morning after when I mount it on the bicycle to go to work?
    I'm pretty scared from thermal-runaway events, and I would like to not keep the battery in the same environment where I sleep... Any suggestion?

    what about -20C if i am using a device that only draw very very low power like 40mAh and similarly slow charging would it cause problem?

      Our batteries protect themselves from charging in cold temperatures and won’t accept a charge once the internal cell temperature drops to 24°F (~-4°C). At this point, they will continue to discharge even down to -4°F (-20 °C). At this temperature, we recommend no longer pulling power to avoid damaging the batteries. Since your battery will be operating in consistently subzero temperatures, we recommend using insulated battery boxes, heating blankets, placing your battery bank inside, or using a heated battery to ensure optimal performance and functionality.

    Most off grid lithium mfrs advise no charging below 32F. Is this merely a safety factor exaggeration or are there different temperature points for different batteries?

    • @dragonfly_energy

      The battery management system (BMS) within our batteries will not allow them to accept a charge when their internal temperature is below 25°F to protect them from unsafe operating conditions. However, if you expect your batteries to need to operate in below freezing temperatures, our internally heated batteries will allow them to continue to function no matter how low the temperature drops!

      I heard this problem is much worse in lfp batteries 🤔😳

    What if it's not charging or discharging and just stored in cold temps?

      We recommend fully charging your batteries and completely disconnecting them for storage. To ensure the safety of your batteries, we recommend not storing them in subzero temperatures.

    What about LFP batteries 🤔😳

    • @dragonfly_energy

      LFP (or lithium iron phosphate) batteries are a type of lithium ion battery.

    hello thank you for good viode , please i have some questions
    1- i bought new Electric Motocycle and New lithium phosphat Iorn Battery i discharged it completly and recharge it 100% , red light of charger convert to Green but when i install iot in Motocycle Screen shoe me that Battery not 100% charged 3 Degrees from 4 degress
    my question what is reason ? is Charger or Battery or display of motocycle ? in my country austria is too cold almost 2 or 3 C
    also after 3 Kilometer distance batter now 2 degrees from 4 !! too fast drain my battery is 60V 40 A
    2 -when i use throttle of mototcycle degrees of battery decrease to two degrees and then come back to three it that normal ?
