15:30 wow he’s really struggling to get them screws in (looks like using PH2 driver and should have used a PH3 instead) also the 280l new version Don’t use the plastic as they will damage the battery, use full pice of foam on the battery only.
Lifepo4 batteries do not care. Truly awesome battery tech. Getting the compression right is the biggest hurdle. Compression to stop the cells from swelling prematurely
Balance the cell before building battery is necessary and required. For brand new Grade A cells, they come balanced. but who knows, if condition permits, you never too careful to double-check.
@@SeplosTechnology Can't we rely on the active balancer you now provide with your BMS v3 (to make things properly, by using a lab power supply) ? Or do you anyway recommend an external balance before, anyway ?
I'd never use a powered screwdriver or drill to start off a small screw or bolt. You are asking for trouble if you strip the thread. Always start by hand and only use a powered tool if the thread is more than 50mm or 2inches.
Hello Sir, Greetings from Turkey, I would like to tell you a little about myself. I am a man who was born without two arms. I want to buy an electric car, but the batteries of the electric car I bought are gel batteries and I do not have the money to make a lifePo 4 battery to replace those batteries. Can you help or sponsor me in this regard? 72 volts I need a 200 amp Life PO4 battery. If I give my address, can you send it?
Please, made a video about how to connect the BMS META who comes in your DIY box kit to the inverter. Thanks you
can we just get the case without battery?
We need 200V battery.
What active BMS system Y recommend for 54S battery?
Which Seplos BMS version is included with this kit?
Esta bateria es compatible con el inversor goodwe salto voltaje ?
Gracias
The torque depend the size of the bolt.mostly at this size 6mm around 10 to 12 nm or hand tight
Nice video done really well, the second part is missing, the software one, how to configure the BMS with a single battery pack or more.
thanks for your feedback
We'll continue the second part. Please stay tuned
@@SeplosTechnology Hi. Any news on this, thanks ?
Great video, why do you in some places have two balance leads to the same bus bar?
circuit board says "NTC", should be heat sensors
Good video !
Sehr gut 😊👍 habe auch Lifepo4 Zellen 45,6 kWh 👍
What is the purpose of the yellow epoxy sheets?
Insulation, prevents current leakage and electric shock.

Is it ok to put cells on side like this?

Hi what causes a BMS to be misread?
I have read that some people balance the cells before building the battery. Is this necessary? Do the cells not come fairly balanced?

How much torque on the screws please?
Fix the aluminum bar with M6 flange nuts. Set the torque index of the electric screwdriver to 10nm.
nice :)
Dureranno parecchio meno le batterie devono essere in verticale

Why didn't you provide compression for batteries 300 kg?
