Re: How to charge a 4 cell module out of the car

When charging the 4S module, be careful : when charging this module, be sure to monitor each of the four cells to ensure that they are tracking; i.e., that the voltages of each of the four cells are identical as the overall module voltage goes up. How do I know this might be a problem? Earlier today...

Re: Global Warming's Terrifying New Math

... I guess panels laying flat out-perform angled panels considerably in cloudy weather... I had noticed that, as my flat panels on the boat always seemed to put out more (percentage-wise) than my angled panels at home. Yay, this morning our AQI = 0, what a difference when compared to the horrors o...

Re: How to charge a 4 cell module out of the car

You have the solution! According to this NOCO Genius 3500 User Guide , the "12v Repair Mode" has a fixed 16.5v 1.5A output. That is 4.125 volts per cell. So, you're in business and can ignore the workaround discussion above. You'll still have to watch it and unplug to ensure you don't ove...

Re: Global Warming's Terrifying New Math

Scary times on the west coast. Hope everyone is staying safe from the fires. .. Nice photo. Our sun as been obscured far more for the last week. Last Wednesday when it was really dark during the day my solar panels put out only 1.4kWh for the whole day, compared to their usual 60kWh at this time of...

Re: How to charge a 4 cell module out of the car

My charger has a DC supply mode .. I am assuming it has some way of limiting the current. Sorry, can't help you there. What does the nameplate or manual say? Admire you for tackling the module replacement, but please do be careful. There's a reason manufacturers don't let their service techs open u...

Re: How to charge a 4 cell module out of the car

Hi vh2q, sorry for the delay in responding - I've been diverted as life is 'interesting' around here... Good that your four cells measure an identical 3.56v. That means that the four-cell module is sitting at 14.24vdc. Since the four cells are already 'balanced', let's see if we can charge or discha...

Re: How to charge a 4 cell module out of the car

I see kiev beat me to it, more elegantly, as below is what I wrote, FWIW... Piece of cake as, unlike LiFePO4, our batteries don't sag when the voltage source is removed. I would also say that it's not necessary to fully charge everything before extracting or reinstalling. You need only to measure th...

Re: iMiEV as workhorse

So, with the Fire Evacuation Warning stopping less than 1/2-mile from my home, it was time to even further enlarge the Fire Defensible Space around my house. After seven months of almost complete social isolation, no haircut, a new beard, and almost no i-MiEV use, I pulled out the trailer to remove ...

Re: Blink Charger

Hey ed5000, that Craig's List Blink EVSE posting has now been deleted. I kinda nudged the EVSE discussions into this thread in order to separate them from the Blink Charging Network . From that thread, ...I also own a broken Blink EVSE that sits in my garage. :) (It was broken when I bought it. I ho...

Re: Tesla to J1772 adapter

The owners of my fave coffee shop will let me play around with the DIP switches in their HPWC to see it I can get the Lectron unit to work. If I can, and if switching DIP2 from Tesla to J1772 still allows Teslas to charge, I’ll leave the HPWC on J1772 and give the Lectron unit to the coffee shop fo...
