Will OptiMate Lithium Select Smart Charger Charge Lithium Batteries on Airstream in Storage  

Updated 03/06/2024 | Published 01/31/2024

Question:

I am replacing my Airstream AGM batteries with lithium batteries. Is this a good charger for the lithium batteries when in storage for a while or is it considered a trickle charge only?

The OptiMate Lithium Select Smart Battery Charger # MA67JR is a great choice for the lithium batteries you're adding to your Airstream. It uses a 10-step algorithm to charge, test, and maintain without overcharging so it is perfect for a storage situation. The charger works with 12V and 16V LiFePO4 batteries from 2 to 120 amp-hours.

Optimate LFP Select Lithium Is it ok to charge 2 lithium batteries 12.8 v connected in parallel remained installed in my RV? Or should they be disconnected and charged individually? Also does this charger automatically recognize the lithium battery to charge or is there a step I need to do like maybe pressing the BMS reset? I'm very impressed with this charger and just trying to learn all It's features.

@DuncanP parallel is fine as long as you're within the 120 amp-hour rating. It is only designed for lithium so it assumes that is what you are charging. You don't need to choose a specific setting.
