US - Bestech CHARGE ONLY BMS modules

I would need one in Europe, sorry. If somebody is purchasing a 12s bms from Europe, write me a message, we can order together!

You going for a bypass BMS? I need a 12S bypass BMS in UK

Thanks @thisguyhere I tried to grab a 12s the other day, but you were outā€¦ perfect timing!

Obviously depending on how you wire itā€¦

Thanks so much I was confused because itā€™s usually 13 wires thanks so much

Zero is the one he didnā€™t mark, thatā€™s the 13th one. But you should ALWAYS verify the voltage with a multimeter before making the balance connection.

This BMS has 12 wires for 12 cells.

But there is no 13 wire

The 13th wire is probably the big ā€œB-ā€ wire

Yeah, exactly. Of course it is ā€œthereā€ just that is how this one is labled. Just to not confuse things. This is where the 12 balance wires go for this BMS, B- goes to, well, B-.

Some BMS have B0 through B12 for 13 balance wires, but the bottom one is electrically the same as B-. In fact, if youā€™re using them for charge-only and they have 13 wires, itā€™s likely you donā€™t even need to hook up B- on those BMSs

got some more 10s and 12s modules in, in case anyone needs them.

bkb has them too.

For posterity; (since a Google search of ā€˜d140 getting hotā€™ sent me here)

D140, with balanced cells, within 0.01 (highest 4.09,lowest 4.08). Set up according to the image in this thread. Charge only.

Bought from https://www.litechpower.com/product-detail/HCX-D140LI12S15A_05.html When connected it get wildly hot. Over 100c at the resistors. Unsure why, seeing that I canā€™t set it up my self. It seems it wants to balance to 0.00 differenceā€¦? Website above says 0.025? And operating levels at 0-85c.

This is FWIW.

I have now dropped Bestech (litechpower) in favour of Daly BMSs.

Iā€™ve had the same thing happen with a Bestechā€¦ all balancers on full-time for no reason, after initially working correctly.

Also Iā€™ve had issues where the charge cutoff was lower than the balancer setpointā€¦ for example, the charge port shuts off if any P-group goes above 4.16V, but the balancers kick on if any P-group goes above 4.17V ā€¦ the end result is that your pack never balancesā€¦ everā€¦

Bestech quality lately has been going downhill, a lot, in my experiences.
