Parasitic drain on Main AGM Battery after Mechanic installed a High Output Alternator & 3-wire kit
Lithium Iron Phosphate (LiFePO4) aka "LFP" its a Dakota Lithium (MFg# 12V135BV2A) brand. Imagine an alternator with (2) positive leads connected, one to each positive terminal of the two batteries. AGM (Main) & LFP (2nd). I'm running an hourly list of voltage measurements and SOC while running...- George Perry - MB

Main Battery Upgrade to Lithium
What H.O alternator to you install? I recently acquired a JS Alternator - 340A. But just posted a new thread as I have a parasitic drain that's substantial now after a mechanic did the installation work. Returning it for re-evaluation on Thursday this week, but low confidence there will be a...- George Perry - MB

Parasitic drain on Main AGM Battery after Mechanic installed a High Output Alternator & 3-wire kit
Parasitic drain after mechanic installed a high output alternator. I'm no mechanic, yet a persistent problem solver, but I lack the tools and space to freely work this problem. Its been a journey. I have a 2012 LR4, 5L NA. I completed a dual battery setup: AGM main X2 PWR (80 AH) + DL+ 135 AH...- George Perry - MB

Main Battery Upgrade to Lithium
I completed my dual battery setup. I had to deviate from the posted method of putting the ECU in a protected case under the brake lines. Instead I attached the horn to another bolt farther back and tucked the control module still under the brake lines but in its original case. I then repurposed...- George Perry - MB

Main Battery Upgrade to Lithium
Thank you CRYA and djkaosone. The additional posts and your considerations are just what I needed to break through my stubborn persistence that was going to get me nowhere in this case. Now I have a new plan to go after and am recharged in my motivation. Originally my 5-day weekend was going to...- George Perry - MB

Main Battery Upgrade to Lithium
Thanks for the inputs. I re-evaluated the options and went with everyone's suggestions about dual battery set-up, realizing the 2012 is too early a model to support Lithium directly. Ideas about best path for inside cab wiring? This would be 4 gauge power wires. I don't think I have enough space...- George Perry - MB

Main Battery Upgrade to Lithium
I got a different form factor to work in my 2012 LR4. But charging profiles with OEM alternator is problematic. Need technical advice, please. Local mechanics not helpful. ChatGPT offers a 250A high-output Alternator from Nations - but waiting on feedback from bolting and fitting. Wakespeed...- George Perry - MB

Hello from California!
Nice Rig Abram! I too picked up a 2012 LR4, but mine is white. It had more kitting from the previous owner and I am adding even more. Pictures to follow at some point. This is my first post and sign-in to this forum. I have a challenge to get through.- George Perry - MB
