Ionic Lithium 12V Group 31 3000 CA LiFePO4 Heavy Duty Battery

Made it through the frozen tundra... down in Nacogdoches TX now and will type out my thoughts tomorrow.

I love these batteries.

 

I have a $70 portable jumper box off Amazon for my 227k mile Kia soul. I have left the lights on, done light and been screwed before. The box jump starts it easily. Granted it's a small engine. It will charge off a USB.

 

Been running Dakota lithium’s in my bass boat for 3 years now with no issues. Have several friends running ionics that fish a lot more than me. They’ve only had a few go bad, but the warranty is great on them. Biggest problem I’ve seen with lithiums is when running in series if 1 goes bad your sol. Also, there’s no warning whatsoever when ones about to crap out.

 

Two months on the Ionic starting batteries running in 20's Farenheight and even down to 5 degrees F one night. During Pretrip clicked the heaters on with the app, started the truck no problems.

Same can't be said for my decision to use the LiTime 12V100ah trolling motor with Bluetooth and BMS to replace my EPU batteries on the frame rail. The batteries perform exactly as advertised. BMS shuts them down at 32 degrees for charging and they don't wake up until 40 degrees. Problem is my inverter runs my fridge, modem, cell charger, microwave, laptop, etc. Big current draw. Also powers the Espar unit. Been dealing with it.

IF (and probably when) I redo the system to fix cold weather performance, I'll probably put in some bus bars and disconnects on the frame and move the EPU bank inside under the center of the lower bunk where it's more temp controlled. And instead of 4x100AH batteries, I think I'm going to go all in and step up to 3x280AH batteries under the bunk. All charged off the stock freightliner alternator.

Reason being is I can run a 1500W cheap ceramic heater off the inverter in the cab while sleeping, so I don't have to burn the bunk heater, which my espar uses about 3 gallons of diesel in a 10 hour break. 10 bucks a day. Also, summertime that amount of battery will pull a full 34 hour break running max bunk AC.

I know, I know, sleeping over discharging Lithium Batteries.

your espar must be dumping it on the ground. Had one for the past 12 years, and I only use a quart in a 10-14 hour period.
