hey, this is my firt build. is ervery thing all right?

what should i do with the 2 negatives wires from the balance wire? nothing? or connect them to the ground? do i need a anti spark switch? is that the best switch location in that schematic? can i use that charger 24V and 4Ah output for 6s lipo

here is my electronic part list. 2x motor 5055 190kv link 2x vesc link bms 10A charge / 10A discharge link i want to bypass the bms 2 3s lipo 5Ah or 8Ah 5Ah 8Ah charger 24v and 4 Ah link anti spark switch link voltmeter link

Your diagram is showing extra battery cells.

3

why? sorry i dont know what you mean

4

Man, 6s normally have 7 balance cables, 6 for the positive of each cell and 1 for the negative of the battery!

your volt meter needs two cables going in and out since it’s inline. It’s also not suitable because it supports 30a current max.

6

hey but there only 6 pins link as you can see

The first dot is the negative one

why do i need more then 30A. the voltmeter is parallel to the batteries. and the voltmeter has a high internal resistance. the greater the resistance, the lower the current is.

This is a power meter, it also measures the current flowing through it, so at >30 battery amps you’re going to melt it. How would it measure power with only the voltage?

is this one right? link details: No power supply required Measuring voltage: DC 3.0-30V blue Working current: <20mA Display: Three-digit 0.4 \ "LED, blue color Refresh speed: Approx.500mS / time Highest input: DC 30V (higher than 30v has the risk of burning) Minimum input: DC 3.0V (below 3.0V, measurement inaccurate or not show Minimum resolution: 0.01 V (<10 V) /0.1V (> 10 V) Resolution: 1% + 1 digit Working temperature: -10 ℃ ~ 65 ℃ Size: about 40mm x 25mm x 23mm (L * B * H) Mounting hole size: Approx.37 * 20mm LED Color: Blue color

here is an update of my schematic. but i think it is worng for this type on balancer/bms

hmm maybe your schematic is wrong. as you can see on that picture. the balancewire has only 6 ports. link

and here is on thread where they have the same problem link

It has 7 pins on the connector. B- B1 B2 B3 B4 B5 B6
