    New Chargery BMS24

    The only way I know to improve balancing is to open the cover and add thermal paste or a thermal pad so that the balance resistors can transfer heat away to the case. Balancing current is limited by heat. NOTE: There are a few models with similar names mentioned in this thread. BMS-24 does not...

    BMS that starts balancing at a set point/different voltage?

    Some of the Chargery products can do balancing at set voltage points and on charge or on discharge options. Check out the BMS16T/BMS16 Pro or BMS24T/BMS24 Pro. I have both. They have a BMS16 (without the T or Pro) that does not do balancing, so get the correct one. Here is a link...

    Anyone dealt with Tech Direct Inc. LG Chem Modules

    Sure, your connections would look like mine. I have two 8s connectors that i soldered to the cells. The connectors and cells on the module are arranged as 1,3,5,7,9... on one side and 2,4,6,8... on the other. So you would have two 8s "Y" harnesses. Do note that the cells are hard to solder to...

    Anyone dealt with Tech Direct Inc. LG Chem Modules

    I use a bms from Chargery. However your needs may be different. How you use the batteries will determine what you need. 01. How are you using the batteries? 02. How are you connecting the 16s battery modules together to form your final pack? 03. What is the average and the maximun current...

    Chargery C4012B 12S balance charger review...UGG!

    My six BMS16's and BMS-24 Pro seem to be doing fine. The Bms-24 Pro does not balance at max amps unless the temps are really cold out. The balance amps are throttled by the temperature. I read on a post some where that you can add heatsink paste or thermal pads to get closer to max balance amps.

    The ELG has a reduction in output power when on 120vac input. 240->180. The HLG does not say that. -YS
