![]() ![]() I don't really know your essential requirements, my packs have enough lead length to reach the board if the board is on the batteries, it should be right on the ends of the batteries. ![]() If those connectors aren't lined up close together you will have a lot of trace area to route. If you want to use up to 4 amps balance current you can put 2mm traces on both sides. If you pop a balance trace you'll never know until you have a major balance problem, so you want them to be fairly substantial. In 1 oz copper a 2 amp balance current trace should be at least 2mm wide. Trace current capacity can be calculated, here is an online calc: It might work, but these are not wires, they are traces which have very little copper compared to wires. Your layout proposal has traces wrapping around the board making lots of resistance. ![]() Impedance/resistance of traces is pretty high on a pc board, especially with the thin 1 oz copper. It is easy enough to move things around on the board, but splitting the connectors the way you showed creates a mess of the traces. ![]() I started with something fairly optimal from a pc board resistance point of view. the smaller the better, as long as you can pull the connectors from the board.Ĥ small mounting holes 3-4mm in diameter on each edge.Ģ-sided routing is fine. This is what it should look like - more or less. why 6? because the 5th one will go to the bms, and the 6th one will be a monitor connector for a celllog. orientation (pin1 up or down) doesn't matter. solid wire will be soldered on bottom of the board for higher amps.Ħx jst-xh6 soldered in parallel. It's quite simple: 4x xt60 male plugs soldered to the board in parallel. In short words: maybe there is someone out there who can do me a favor and make this for me? it doesn't have to be perfect, and i guess as soon as i have something to work with i can refine it to my needs. i watched several tutorials, but the result is never as expected i downloaded the jst-xh connector library, but as soon as it comes to traces on the board it get's weird. This ask for help goes out to all the guys who know how to draw a quick schematic and board layout.įor two days i tried to make one board which should be uploaded to osh park for making, but i just can't handle eagle or diptrace good enough to make it happen. ![]()
