Need an AC/DC Charger - ISDT BattGo T8?

Let me know if you want a parts list and links of wires and connectors and stuff for this. Its almost all on amazon.
yes please . . . what is the loom you are referring to? I've got and 8s setup for 24v. If I buy the charger, what else do I need to charge with AC? I assume just a power supply?

Does the power supply have to be 500w? What is the minimum power supply that I can use?!

Thanks!
 
I think Larry is done with this thread so hopefully ok to hijack it...

I only have 4S and 6S batteries. This is the loom that I use:

The key is JST XH is the most common size for the BattGo and HobbyMate and other chargers/monitors. You will want the 8S version of course.

I like ones like this since the wires are long but i've often soldered extensions on and put a ring connector on the end. These are technically extensions but I've cut the female end off almost all of them - they can be used to make a longer set too easily, this is a nice feature.

Hopefully this helps, apologies to Larry619 for the use of his fairway.

Regarding a power supply, i still do not own one. My power supply is the bright thing in the sky which i use with an SCC to charge a battery which acts as my power supply... part of the beauty of having bought more LiFePO4 batteries than a normal person would.

If you happen to have a hefty PC laying around, i'd try using the power supply from that to feed the BattGo. The XT-60 connectors may out at 60amps technically and they get warm around 50 amps so i'm not sure i would recommend a lot more than that.

Adding more tidbits:

These for extending the loom wires:

14awg for the Xt-60 connectors:

Shrink wrap for XT-60 connectors - it makes them pretty solid:

Nice battery disconnect:

Cheap and cheerful digital volt meter - its really pretty good!

This was a life saver. I could not solder to save my life until i got this, now i'm pretty good:

By all means please continue the discussion. Due to the Coronavirus, i've diverted my attention (and money) to other matters at the moment. My batteries have remained untouched in my garage. I still need to bottom and top balance them and i'm still in need of a bench PSU and an AC charger.

I even still have the BattGo T8 in my Amazon cart lol.

I'm looking forward to your parts list!
 
....i should also add that Will's latest video with the all-in-one MPP Solar unit is really intriguing. If i go that route, i may not need to worry about a separate AC charger.
 
I'm still a little confused . . . do I need a power supply that can supply the full 1000watts? IE could I connect this directly to solar panels to charge batteries?
 
. do I need a power supply that can supply the full 1000watts?
I think your power supply can be less than 1000w, otherwise it woyld not be very useful and easily used. I recall the input voltage is 10v-30v. (From memory so make sure to rtfm).
