    Any harm in using a higher balancing current?

    My Monstrous Beast™️(14S10P, 140 Samsung 18650 26j cells) pack is back in actions and sufficiently reinforced and shrink wrapped I do believe. Now I'm trying to get the settings on my Daly Smart BMS dialed. I can set the active balancing current anywhere from 0.050ma to 1a and it can be set...

    Once again require assistance 😅 this time with my speedometer....

    So ok the way to work today I noticed that my speedometer was only tracking speed if I was either pedaling or engaging the throttle. As soon as no load was applied to the system the speedometer would drop to 0km/h regardless of actual speed. Didn't think much of it... Powered up the bike to...

    Can a 500W brushless bafang rear hub motor safely handle 750W?

    Hey everyone! As the title states I'm wondering if I can safely put the 500W motor on my 25A 750w controller or if I need to limit the current first? Threw my main motor wheel out of true slipping on some ice so need to use my old backup motor for a couple days...

    Question about ideal charge cycle for my situation...

    Hello again 😅 I was just wondering what the best charging habits would be for the longevity of my new battery. I commute 75Km daily, by the time I get to work I've got about 65% battery remaining. If I bike home without topping up the charge at work I drain down to 30% remaining capacity on...

    Is there such a thing as a 14s balancing board that uses the same connector as a standard Daly BMS?

    Hello again everyone! I had a mishap with the new battery and ended up cracking the case real good 🤣 nothing was damaged internally and it gave me an excuse to look inside the pack and see what the voltage was on each of my cell groups as well as to check the quality of the welds and that none...

    Question about parallel packs with mismatched voltage charging each other...

    Ok so... My question, if you had a 48v and a 52v li-ion pack paralleled but which direction would the lower voltage pack get charged via? I.E. would the current flow from the higher voltage pack into the negative terminal on the lower voltage pack or would it flow through the positive terminal...

    Thinking of upgrading dumb Daly BMS to a JBD smart Bluetooth BMD

    Does anyone know if the wiring order is the same on both BMS? I know they use the same connector but if the wiring order isn't the same I'm assuming it won't be plug and play?

    Found a used 52v 21Ah Biktrix pack, it's been in storage without a top-up since August 2021...

    The pack supposedly never been used but it was stored a basement at full charge for nearly 2 years.... What are the chances the pack is still good and worth purchasing as a backup? The seller isn't able to check what voltage it's resting at after all this time but the LCD on his bike shows it...
