    Soldering 18650s

    It´s been stated, over and over again ... DO NOT SOLDER 18650s, but seems like almost every battery pack you see on Youtube, by experienced builders, actually solder their packs ??? Very few spot weld, and the majority solder their smaller busbars. Is soldering okay, if done properly, with the...

    BMS + Balance Lead ?

    Cheers floydR 🍻 Balance leads just for individual pack monitoring ;) Okay to connect an extra xt60 lead directly to B+/B- off the battery pack, to discharge bypassing the BMS ? (y)(n)

    BMS + Balance Lead ?

    Simple question for the doyens. When connecting a separate, external balance lead, to an existing battery pack with BMS, is it just a matter of soldering the corresponding cable leads to the balance points on the BMS or parallel packs, in order to charge the pack using the external balance lead...

    rePackr - Divergence/Deviation

    Thanks Daromer I used an XTAR VC8 for IR and GRAD(Capacity, Charge/Discharge). SOH on average was about 80-85%.

    rePackr - Divergence/Deviation

    Are there any standard Divergence/Deviation +/- tolerances that should be adhered to, when optimizing pack build, using rePackr ?

    4s Buck Down ?

    I settled for 7s5p + 7s BMS´s + Buck downs, for my 12v packs, balanced charged with an ISDT Q8 BattGo 500W 20A Charger/Discharger for 1-8s. Might seem overgunned, but fits well with my specs, taking overall capacity/Vdrop into account.

    4s Buck Down ?

    7s would definately do the job, plus better bucks with a higher output(when needed). These bucks have a 3A max rating. Lowest voltage @2.8/3.0(19.6v or 21v) still leaves alotta room, as the min input for my specs/buck is 15v(13.5v + 1.5v(min).

    4s Buck Down ?

    Planning on upgrading/replacing some relatively old/tired batteries in my RC Baitboat i use for carp fishing/baiting up. My boat has twin props, each powered by 2 x 7.4v li-ions, 1 x 12v lead acid for a Raymarine Sonar, 1 x 12v lead acid for a wifi range extender, and 1 x 6v lead acid for a...
