Charge ports and fast charging

I don’t know of one specifically for fuses, but just follow this in general

[Serious] How To Solder-The Complete Tutorial From A>Z

Here is a tutorial on how to solder. We will discuss everything from how-tos, what tools and tips & tricks. - Here is a list of what you need. Tools | What you actually need"] First off, a soldering iron, not a pistol. Basically a long stick with a metal rod. Solder. It needs to be 60/40 that has a rosin core. People use 63/37, it is personal. Flux Helping Hand/soldering Jig Brass coil/or just use a damp cloth that you don’t need. Desoldering Braid - Sooooo many soldering irons! Which one? …

Sorry, shoulda phrased my question better as I’m really just wondering where to solder the fuse onto. Is it onto the charge port cables or on to the main battery leads or somewhere else?

[b264]

On the negative lead of the charge port

@b264

BMS bypassed with loopkey and discharging with lights/accessories circuit

If your BMS doesn’t have C- or CH-, then connect that wire to P-

Is that 2 5s chargers?

[TheRef]

I love mine… it’s big though and probably a bit of an overkill for me… but when you hear that snap… oh baby!

[Fosterqc]

it was parallel 12S I thought

if you want to series power supplies you want The Last Power Supply (Charger) You’ll Ever Need

[TheRef]

I thought you couldn’t parallel psu

[Agressivstreetlamp]

parallel chargers are iffy. but you can always try it. Hook chargers in parallel without anything else. just positive to positive and negative to negative. if the lights stay red when its just the chargers in parallel then theres no current flowing from one charger into another. problem is, if there is an issue, itll probably damage one of the chargers

and these are 12 supplies in series. not parallel.

Use a separate fuse on each charge port

[TheRef]

Or a diode right? On the line? I need to series them anyway haha

[b264]

The diode will bring down the charge voltage

[TheRef]

Ah true… i planned on shooting over. I was going to do 3 or 4 psu depending on their voltage output.

[Pedrodemio]

No, two 10S chargers in parallel

[mackann]

This is my favorite one that we use:

[DEEIF]

What type of charge port is that? Also, what company makes those chargers?

[mackann]

12S 50,4V 10A Supercharger - Bioboards

Chargeport is not a normal one, but name is YZ-20

[Rossy]

What do y’all think of these?

For the lights, does this diagram indicate I won’t need a step down transformer / converter? I’m looking into how to light my board at the moment, and I’ve read I’ll need some type of way to step the voltage on the battery down to something acceptable to the LEDs… Does the BMS handle that? I’ve ordered this BMS for my 12S battery: Smart BMS – 12S – esk8Life and plan to bypass the discharge component of it. Thanks!

[b264]

There are many ways to add lighting, some need a step down and some don’t. Most do. It’s highly specific on exactly which lights, how they’re connected, what your battery voltage is, what you want to achieve, how failures are handled, et cetera

[sleepless]

@MarkVa1

Does the BMS handle that?

This is a good question. On a charge only balance wiring, can you set up output current limits within a Smart BMS to (reliably) output say 5V for an Arduino or 12V to directly power a string of LEDs from the P-?
