Hello. I have a 210Ah 12v lifepo4 battery that I've been charging with a Noco Genius G7200 charger. It's been charging for at least 30 hours and isn't going past the 75% indicator. Is this normal, should it take this long? Is the charger not the correct type? (images below) Could the...

Hello. Just looking for confirmation on my assumptions below. I have a Renogy 40A Rover Elite MPPT controller. I currently hook a single 160W solar blanket up to it, but now I need a bit more charging power, so I'm looking at getting a second blanket. My current blanket outputs around 18v...

I purchased a PZEM 051 meter such as this: It's not bad, but it only seems to show me how much power has been consumed. I'm wondering if anyone can recommend a power meter that displays power remaining. I only want to spend around $20 - $30 if possible. Thanks.

Wondering if anyone can tell me whether these marks on some panels I have indicate damage or anything else??? The above looks like crush damage. and this one looks like it indicates where something is wrong, broken faulty???? This panel only had these 2 marks. Thanks for any help.

If I have two panels connected to a single MPPT charge controller and the output of one panel is greater than the other, is there a risk that the more powerful panel could feed into the less powerful panel and damage it? In the diagram below, is there any risk of PV B damaging PV A, as it is...

Hello. I bought a Noco Genius 7200 charger several years ago, before I was interested in lithium. All the documentation says it works with lithium batteries and there is a lithium setting on it, but I'm a little unsure. I'm wondering if anyone else has any experience with these chargers and...

I'm setting up a new 12v setup in my RV. I have a single lifepo4 battery which will be charged from a seperate MPPT CC and DC-DC charger (2 physically seperate items, not combined). Should I connect the negative battery terminal on the lifepo4 battery to the vehicle's chassis? When I look at...

Hello. I have a 210Ah Lifepo4 battery and want to add a 100Ah Lifepo4 battery in parallel to boost capacity. Both batteries are Lifepo4, same voltage (~12v) but from different manufacturers. I know I can add them in parallel, but I'm wondering about charging and discharging. Is it safe to...

On my RV I have a 200Ah Lifepo4 battery and 250w of solar panels. My current plan is to purchase a seperate DC DC charger and MPPT charge controller. However space is an issue in my RV, so I was thinking of a combined Charger & Controller. But all the combined charger/controller combos I've...

Hello. Just looking for some help with my proposed setup. I've decided to use 2, foldable panel arrays to recharge the vehicle mounted lithium batteries in my camper. I'm wondering about the physical connection of the two arrays and MPPT controllers. Can I simply get a Y cable and plug 1...

Hello, Is it possible to determine what capacity panel I can get, for given dimensions? I have a space on my RV of 1200mm x 650mm where I can mount a panel. Can I use those sizes to determine what capacity panel I can get? Currently I'm just Googling 200W panels and looking at their...

Hello. I'm trying to work out how much solar I'll need to recharge 67.5A back into a 12v LifePo4 battery in 4 hours. I'm getting confused by terminology. I'm looking at a 160W panel. It's listed as having a Max power current of 12.2A and a Max power voltage of 18V. Is that what it's supposed...
