Re: 40 amp fuse question; blade vs bolt down

Thanks a lot! I see what you mean. The distance between the 14 volt source and the fuse is a concern. Maybe I need to mount the ANL fuse box by itself right by the 14 volt source, and then have the switch and precharge resistor in a separate box a foot or two away? I illustrated that here in this pi...

Re: 40 amp fuse question; blade vs bolt down

Thanks Amberwolf. Yes, the only the positive side goes through the switch box, and, as you said, current goes through the power resistor only briefly when the capacitors in the inverter are being charged. I am thinking I may try putting the power resistor on top of the ANL fuse box cover (as shown i...

Re: 40 amp fuse question; blade vs bolt down

As I novice, I have no clear idea what kind of box to use (or how to mount the power resistor)? What is the best thing to put on the floor of a car that will stay cool and be safe. The components I have are: 1) a 4.8 " long ANL fuse block 2) a 3"x3" Switch 3) a 2 Ohm 100 Watt power re...

Re: 40 amp fuse question; blade vs bolt down

Image This shows a picture of the fuse holder that got somewhat warm and which held the 30 amp blade fuse which blew after about 30 minutes of operation at 26 amps or so.

40 amp fuse question; blade vs bolt down

I am working on a project where an inverter draws about 25 amps* continuously from a 13 volt battery-based source. I am using 10 AWG wire with 30 amp blade fuses in in-line fuse holders on the 13 volt wires. (Something I got on Amazon that happened to have the connectors I wanted on both ends and se...

Bafang G310 losing power with time?

I use a Bafang G310 with a Baserunner controller and a 36 volt battery on a mountain bike. I have been doing a sort of regular commute with that for about 3 years, and I have noticed recently that I seem to be getting a bit less torque (maybe around 10% or 15% less) than I used to for the same throt...

Re: Charging a portable power station from a Tesla Model 3

Does that (above) seem like it will work? Does current surge tend to be an issue with converters? I've used that family of boost converters (12V to 15V in my case), and it will work if you don't mind risking burning your Tesla to the ground. I only used them in a high-temp resistant engine compartm...

Re: Charging a portable power station from a Tesla Model 3

It's much easier on a Chevy Volt. All I do is connect the 2kW sine wave inverter to the 12V battery with short 6 gauge wires then run the car with the shift button clamped on and in park. I have the wires and a big Anderson connecter permanently installed on the battery. But since most use cases fo...

Re: Charging a portable power station from a Tesla Model 3

What do you think of this inverter? I am thinking that even though it is tempting to get one with higher VA rating, that one with a lower VA rating may have smaller capacitors and less tendency to create surge current each time it is connected to the car and powered up.) In fact, maybe the 250 VA ve...

Re: Charging a portable power station from a Tesla Model 3

Those DC-DC converters usually get only about 60% of rating before turning into a hot mess, at least the several I tried that looked very similar which I use for converting my 14S bike pack down to 12V for running automotive accessories as well as charging my FPV drone setup with when out on a back...

Jackery E1000 charging

The Jackery E1000 comes with two charging options. One is a cable with a car outlet on one end and an 8 mm plug on the output end, which charges at a constant 75 Watts from 10% to 90%. The other is a 110 AC powered 24 volt output converter, which charges at a constant 145 Watts.

Re: Charging a portable power station from a Tesla Model 3

I do really appreciate your advice. I thought I was following it, by getting the 24 volt output converter rather than a 48 volt , but maybe I did not see the big picture. I have never really done anything that involved much power before, so I have a lot to learn. I really appreciate the warnings abo...

Re: Charging a portable power station from a Tesla Model 3

So then the chance that you could charge the E1000 more rapidly by just supplying it with 36 volts at the 8 mm input is really really low? For the 4th or 5th time, 30V is the max DC input voltage. 36V will either not charge or will fry the charging circuit. As discussed in this thread, there are ab...

Re: Charging a portable power station from a Tesla Model 3

Looking at those voltages you just posted, I am guessing now that the E1000 is 6 groups in series, 6 x 3.6 = 21.6 volts. And the the E1500 is 10 groups in series (36 volts). I get that now. Correct I guess I am not sure at all how the MPPT charging actually is implemented in the Jackery. I don't un...

Re: Charging a portable power station from a Tesla Model 3

True. I don't really know much, but I just kind of thought that with bike batteries you can charge at 2 amps or 4 amps or 6 amps or ..., and I was hoping to be able to charge my E1000 a little faster. I would be fine with 36 volts (216 Watts), but I haven't seen a lot of options for 12 volt to 36 v...

Re: Charging a portable power station from a Tesla Model 3

Is the E1500 a higher voltage battery? Does it have longer strings? I imagine that both are made from 18650 cells. I was assuming that the difference in capacity was due to larger groups and that the overall battery voltage is the same for the E1000 and the E1500. But maybe my assumption about that ...

Re: Charging a portable power station from a Tesla Model 3

" But you're not asking about amps, you're asking about volts." For the E1000, my understanding is that the charging is MPPT, but with a current limit of 6 amps. So when you charge with a solar panel, you are on the MPPT curve, and, On the other hand, the 12 volt charger charges at 12 volt...

Re: Charging a portable power station from a Tesla Model 3

I see. Well that could happen pretty easily, because the 110 AC charger for the Jackery E1500 has a 48 volt dc output and uses the same 8mm plug as the E1000 charger. They look very similar and I think someone could very easily plug that 48 volt charger into the E1000 by mistake (or trying to get a...

Re: Charging a portable power station from a Tesla Model 3

Well, I see what you mean. That is in the technical specs. But I wonder what would happen if you connected that 8mm charging port, which usually takes 24 volts, to a 48 volt source? Would the BMS trip or something? Would something bad happen? Or would the MPPT just limit the current to 6 amps and c...
