AI is a terrible source of information. You should never rely on its answer and instead follow up with a review of its sources.

As an aside: from someone deep within in the industry, this whole "AI revolution" is BS (at least on a consumer level). It's smoke and mirrors and performance art. It is good at some things, but we simply aren't at a place where you can trust the output without verification. There's value in using AI to help guide you down the path of research, but you should never take an AI response / result as fact.

You would need to monitor the battery by use of a battery shunt. I have a victron bluetooth shunt already, so these batteries meet all my needs.

I've been running my boat's trolling motor with this battery. It's half the weight of the 50ah SLA that I had been using and twice the capacity. I'm loving it. I did add a $15 digital waterproof battery monitor "fuel gauge" inline that is handy to have. I wear a tinfoil hat so no bluetooth is fine with me.

Would these pair up with a 100ah Litime battery or should they be kept all the same brand? For a van solar setup

Are these good replacement for Ryobi riding lawn mower?
ask AI. My guess is no. AI told me its too "slow" to be used for motion such as a good kart.

I am learning all this myself, so I am not an expert. I suspect that you check each battery's specs for charging, absorption, and balancing. If they match up, you probably can. Your solar converter will also need to be able to handle the added demand. If the Litime is bluetooth enabled, it might affect those readings. Having said that I have a wattcycle battery and even though I would like to add this one, I am passing because the wattcycle is bluetooth enabled and I want to keep as many variable out of my system as possible.

I've personally found ChatGPT to be very helpful in math related tasks. It came really close to helping me figure out this 12v agm battery I got for free. It was definitely worn out but still produced power. So I connected it to a 1000w inverter and it came really close to showing me by the voltage it was reading how much power it could run in wattage
