The NorthStar AGM Battery + Voltage Booster Upgrade

Pretty sure there’s some mail agreement in place for “Commonwealth” countries. Got mine in a little over two weeks. Mind you, I get mail from Germany faster than I do from the West Coast. Go figure.

 

Here's a little testing I did. Only the starting battery connected, fully charged 2 days ago, like 80* out. Pretty much saw a 0.5v increase across the board using a multimeter. Low side was at idle and high side was at 2500rpm.
1n4001-1n4007 = 1.1 Vf(1A)
RL201-RL207 = 1.0 Vf(2A)
1n5400-1n5408 = 1.2Vf(3A)

 

Oof. Just emailed the seller on Ebay asking for an ETA for the voltage booster I ordered a month ago. They said probably about 4 months from when I ordered. That's a bummer as my new X2 battery is just sitting on my counter. Don't really want to install it until the voltage booster arrives. Any recommendations for keeping it healthy during my wait? Proper trickle charger? If I installed it and plugged it in and trickle charged it during weekends would it be ok? From previous posts I'm guessing yes.

 

Sucks kangaroo land post is getting hit so hard with this.. You'll be fine to install it. Many people don't know or care that they need a higher charge and the batteries don't implode. An occasional full charge would be good.

Anyone want to buy a booster without the wait?

 

Yea but I'd hate to damage the capacity of a $300 battery by not charging it correctly for a few months. I'd feel better topping it off regularly. That's the whole point of this forum yea? To prevent under charging these dank batteries causing slow but lasting damage? I get what you're saying though. It would be a minimal issue if at all. I'm just anal and overthinking shiz with my truck. Every time it makes a new noise I freak out lol

 

It's your truck, your money, if you don't want to chance a couple days, weeks, months of life then it sounds like you're still starting and rolling as is so just roll with it. I hope yours is delivered far sooner than mine was.

 

Thanks man. Current battery is fine, went for the upgrade during a sale and in preparation for lights and winch upgrade. Agreed, that's a long time for any purchase to show up. Wish I had looked to see if anyone was selling one before ordering from down under. GLWS!

 

Take it you liked the fuse tap version you made, I like yours but not going to take the time to make another one.

 

I charged mine overnight about once a month before I got my booster. Suppose only time will tell if they last as long as they should, but Im sure you will be fine

 

The modification to the ECU through vFtuner works like a charm.

 

For us 3rd gen owners, looks like @BortisYeltzen has found where to adjust the alternator output with VFTune. Not sure if it’s posted here yet.

Literally the previous post mentioned it, but the link is nice to have

 

DISCLAIMER:
For the record, I’m no “battery-oligist” or anything. I am an OCD Mechanical Engineer in Aerospace, but that doesn’t count for a whole lot when Electrical Engineering is involved. I’m feeling my way through this stuff but I typically err on the cautious side and then increase if needed.

 

Voltage booster showed up, only took 2 months. Not too bad in the long run! Voltage when cold looks to be at 14.7 and when it warms up sits about 14.3
Definitely happy with it so went ahead and installed the X2 battery today.

 

I believe this is another option for the voltage booster upgrade -
