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

Hooked up NOCO in "repair mode" and it's bring up the 4 pack slowly. Took all morning to get from 4.06V to 4.15V. It's delivering 1.5A. So I think that's the ticket. I'll bring it up to 16V, check the balance, and then ship it over to the island. I'll bring the existing pack to 4V per cell...

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

Great! Thanks. I can put it on a boat or there is an air charter service that says it's AOK to bring on board with me. Will charge that sucker up to 4V per cell, and when I get to Bahamas, will charge the rest of it up (or discharge) to match (have hobdrive). Anyone who wants a free vacation and is ...

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

I am in Texas ... car is in Bahamas. No option but to fix it myself. NOCO Genius 3500 ... "repair mode" supposed to emulate a DC supply at fixed voltage 16V but I a pretty sure it's current limited. Is there any (safe) way to test this mode? In open circuit, you can't put it into this mode...

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

Thanks. I am assuming we are not talking about a tiny electronic resistor here, the heat would burn it up? that's why I was looking for a common object that might serve as a resistor and take the heat ... and the way I measure them my vise grips have a resistance of about 1. 4 ohms. With the added b...

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

The replacement 4 pack showed up today. Each of the 4 cells measures 3.56V. So not dead and no bad cell. I plan to swap out the entire pack, even though only 1 of the cells in my vehicle pack is lagging significantly, and one other is a bit behind. So now about the charging. I am hesitating to hook ...

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

My RC charger is a "Triton" and it says it charges both Li Ion and Li Po batteries, up to 4 cells (which is nominal 14.8V) 2.5A max charge current. The manual says when set to Li Ion mode, it uses the "constant current/constant voltage" method, ie you set the current and it suppl...

How to charge a 4 cell module out of the car

Saga continues. One of the 4 packs in my drive battery is a laggard according to Hobdrive. Cell 41 is at 3.79V when all the others are at 4.1V so it triggers the turtle for the whole pack before one gets very far. Bought a good 4 cell pack and plan to switch out. I read on this forum that one must c...

Re: hobdrayv - and i-MIEV ion zero, show electronic control units, reset errors

there was no miev option in the menu when I downloaded the app. i had to go online and update the models, then there was a 2010 Mitsubishi I-Miev option and that is the one I chose.
