Lithium conversion concern

[Durb]

I just replaced my battery with a Battle Born 100ah and my converter with a Progressive Dynamics unit. When I'm plugged in I show 14.5 volts which is easily a volt higher than before (most of the time). Do I have to consider protecting the circuit boards in my fridge and water heater in a 12 year old trailer? Is this even an issue or am I over complicating things?

Bert,

Good question. SiO2 experience level for RV usage is low. Don from past posts uses his RV when it's cold so he's interested in batteries that don't have temperature limitiations. And lower cost is a nice benefit. The SiO2 batteries certainly look promising.

Are they really drop in or kinda work, but not optimally? And I don't know what system comes with the new camper. It doesn't seem like the charging for AGM's is the same for Lith. ( variations in charging input at various stages in the charge cycle, etc.)
I've leaned enough times that there can be a vast difference between proper and "Ah, It'll be fine..." and usually that difference ends up being $$$$$$

Apologies to Durb, don't mean to hi-jack.

BFL13,

You can Li all you want!

If there are an affordable cold version Li, I would own a set. As it is, next summer I intend to come to BC and pick up 4 to 8 SiO2 jars.

Where you getting them in BC?

Thanks! Any experience with them? I like the idea of the kits and wonder if I got one, if I could hand it off to N.Lite or BF to have them install it when I order my new camper, instead of their stock unit? I hate the idea of getting a new camper only to have to swap out new parts to change to Li. And I'm not gonna even attempt a DIY and doubt any place on the island is reliable enough to do the install.

No need to be concerned - and because this is dc, much depends on where you are taking the voltage measurement at... It’s always best to measure real-world voltage directly at the battery’s terminals...

Just an FYI - Costco is carrying Lithium batteries, at least online. Good price too.

Suggest read threads from this forum from a few months ago that went into the whole PD thing. I don't have a PD or Li (and never will! 🙂 and have been banned from even saying Li because I don't have a dog in this race. Oops I said Li , my bad! 😞

No issues at 14.x volts for your electronics. the fridge is good until 15.4 , EG.

The real question is whether you have to limit the time at 14.4 or so and if it even goes too high with the Battle Born, depending on which PD model you have and what that might really mean.

Recent discussions on that here left that all as an unknown, with some choosing one way and some another.

I don't know what is the correct answer.

Thanks. PD9160AL. Is it wait and see then?

The bulk charging voltage for flooded batteries is 14.4-14.8V so I would not expect any problem with your electronics.

You've been undercharging your batteries for 12 years.
