Lithium ion batteries

Just intalled 2 EWT Lithium batteries on my 22QB coachmen Freelander. They both have PCB/BMS function. Do I need to replace the converter/battery charger. And where is this converter located?

there is mixed advice on whether to replace the converter / charger or not. find it and get the make / model number. then call the battery manufacturer and get their advice. there are many articles on the internet about how to charge the new batteries.

many times they are located behind the power distribution panel. sometimes they are behind a basement storage wall. if any of the basement walls have an access panel in them take it off and look to see if the converter / charger is behind the wall.

lithium ion batteries

I have seen many videos on Utube regarding replacing the lead batteries and I get mixed advice. My concern is if the existing setup on my rig is sufficient to keep the batteries charged.

Lithium batteries have a different power curve than a lead acid. You will need a charger that is lithium aware.

I programmed my Samlex EVO-2212 Inverter/Charger for my Battle Born Lithium batteries. I also reprogramed my Solar Charger Controller. I called Battle Born for the correct settings.

Contact your battery manufacturer.

I was dry camping this weekend from Thursday to Sunday night. I noticed that every time i tried to turn on the generator, the interior lights went dead. Then I had to turn the engine on in order to start the generator. Once the generator was going everything was working just fine including when I shut off the generator. The batteries seemed to be working fine. I noticed that as long as I did not try to start the generator, I had no problems with power inside the coach.

My 100Ah Battle Born batteries have a 200 Amp Surge Current for 30 Seconds. With 400Ah, I have a 800 Amp Surge Current to start the generator. I have had no problems starting the generator.

Find out what the EWT surge current rating is.

Let's say that the surge charge on these batteries is not enough to get the generator going. Is there anything I can do to increase the surge just to start the generator?

You can hit the emergency start to tie the engine battery to the house batteries. But you would need a second person as the emergency start button is in the front. You can install a remote generator start to put next to emergency start button.

With four 100Ah Battle Born batteries, I have had no problems.

what make / model converter do you have. i take it that you are still using the stock lead acid converter. on the battle born website they say their batteries work with several lead acid converters. i contacted them to understand this (why buy a lithium charger if the lead acid one is ok)? they said the lead acid chargers will charge the lithium batteries, but not fully. it may be possible that your charger just isn't charging the lithium batteries so that they have enough power to start the generator. i would get the info on the charger and the generator and then call the battery manufacturer and have them comment. it might also make a difference depending upon the type of generator. i would expect an lp generator to take less to start followed by gas followed by diesel.

I upgraded the converter charger to one for Lithium from progressive, but still have the same problem with the generator not starting. I have two lithium batteries hooked up in parallel for a total of 200Ah. I only have room for these two batteries in the step compartment. I wish I had more more I put four just like Robert. I love his set up but its costly. Just need a little bit of surge. I never figured I would have problems with cranking power off of these batteries. They perform great for running all the lights in the coach for days on end. But, can't start the generator. I have to start the engine and go through this process every time now.
