- We bought these 2 batteries (amzn.to/3NT8AiQ) to replace the AGM battery we had in the RV when we bought it. They worked well, but I was not sure I got everything I paid for. Let's test them.

Have you used these batteries? What do you think? Is there another brand you recommend?
I just ordered a 200 ah one off Amazon for $380. Hope it last longer than my previous gel battery which made it 5 years.
Good basic test. I'm looking at these on Amazon.
Thanks. They have served me well so far.
When you install these in the RV would you please repeat an RV’s A/C test to see approximately how long the RV’s AC will run on the 2 100Ah batteries. I realize the ambient temperature will determine how long the A/C compressor cycle runs.
RV AC units are usually 13,500 or 15,000 BTU units. Based on that you will probably get about 1 hour per 100ah battery if you were going to run a RV AC off of them. That would be per AC unit. We have 2 installed on our new one. We probably will not be doing that in the RV from the batteries. We would use our gas generator for that if needed.
I bought two lithium hundred amp batteries off. Amazon opened up to see what’s inside and there was no BMS nothing inside other than cells
Really. What brand were they?
Hi I would like to know, I would like to buy that battery tester to get a true understanding of how much capacity my battery has left. Does that tester reset the counted ah. When the inverter starts charging the battery or does it count back wards? What I'm trying to understand is if that battery tester resets every time the inverter starts charging the battery when the mains comes back on? Would love to know. Thanks.
I have to reset it manually. It's a cheaper monitor, but I am pretty sure they have better ones on Amazon like this one: amzn.to/42QInrG
Is it safe to just sit this kind of "non-marine" chinese LiFePo4 on top of a rental boat while in open, heavy rain or should i look for a marine grade battery? How likely is damage by doing it? Sorry about the dumb question :D
I would cover it to keep it as dry as possible. Like a battery box or something like that. They have chips and such inside them that could get wet and fail. Other than that, I would not have an issue using it in the rain.
how much does the battery weigh?
It says 25lbs. I think that is about right.
DC House is $176 on ebay. Better to get Litime battery. Its the best all around. In general batteries prices are dropping like a rock. Buyers market.
True
Unfortunately, the cheap $30 Ah meter that your using can be off by 15% to 20%. We paid over $10,000 a piece for each one of our DC load testers that we use, which provide 0.05% accuracy.
So you have a better video on your channel then ...
No, we don't advertise batteries. The results of our battery and inverter tests are not meant for public disclosure. @@MrJackson66
This cheap one has been accurate enough for me. I don't need pinpoint accuracy to the thousands of a watt. If it's off a few watts, that is fine. It's nowhere near 15% to 20% off. Maybe 1% or so.
