I'm looking for a throttle for my trolling motor. I picked up a controller (https://www.ebay.com/itm/100A-50V-12V-24V-Reversible-DC-motor-Speed-Controller-PWM-waterproof-box-arduino/172858600514?hash=item283f2cec42) which accepts several different throttle types. The simplest would be a linear

Re: [EVDL] Dual Voltage EVSE charge controllers

I thought that the OBC wouldn't draw any power unless it had a PWM signal from the EVSE. In the case oy 2016 Kia Soul EV the OBC will draw anywhere from 6A through ~28A on 120V and 240V. It may draw less than 6A but I didn't program my OpenEVSE to go below that amount. David Nelson On Thu, May

"the executive calls out women as struggling harder with EV charging cables more than men." Don't let my wife know. She thinks it is easy. Even plugging in the CHAdeMO plug into our Kia Soul EVs isn't a problem. I don't thi k that exec knows what he is talking about. Get Outlook for

Re: [EVDL] NMC backpedaling, 2be like TMC> 2sell EVs that aren’t EVs

"Well, to be fair I have always thought they picked a bad spot for the port." I disagree. I have been in situations where I was able to charge because Kia put the charge port in the middle in the front. Side ports would not have worked. Of course, Kia did not put the port angled up so that

Re: [EVDL] looking for 40kw battery leaf

I don't know where to source a 40kWh (note it is not kw, but kWh, kilowatt-hour) battery for a Leaf but I seem to recall there was some connector change when they went to the "lizard battery" from the first one. You may want to research that part, too. On Tue, Nov 2, 2021 at 1:37 PM redscooter

That is awesome! Someone did something similar to a 2016 Kia Soul EV and found that the GOM would only display a little over 150 miles, does the LEAF display show the 250 mile range or something else? On Wed, Mar 16, 2022 at 10:14 PM Cor van de Water via EV wrote: > > Hi gang, > Just a short

[EVDL] Need to find a blocking diode for charger output

Hi, I'm replacing the T-875 battery pack in a golf cart with a 48V Dakota Lithium LiFePO4 battery. I also ordered their 15A charger to make sure it would play nice with the builtin BMS. I was very frustrated and disappointed to discover that this charger puts a continuous 0.12A drain on the
