I have a 24 V battery and a Daly bms When I check the voltage from one end of the battery to the other I get 27.1 V when I short out the negative cables off the BMS and then plug in the balance leads it starts out at 27.1 V and then the voltage continues to drop until it reaches the 14 v...

Thanks, tried that also....no luck

Yeah I did that, still don’t know what the issue is

Are you using a common or a seperate port BMS? And why did you choose the one you did? Gary

Perhaps because as an example every time Will tests something with a low temperature disconnect it fails... I’m not saying that this isn’t exactly what it says but history shows when it comes to LifePo4 batteries that claims and reality can be two very different things

It’s just too good to be true they clean their batteries can be used down to -20° C https://www.lifebluebattery.com/rv-boat-low-temperature-lithium-ion-batteries/100ah-lithium-low-temperature.html

Thanks for your great reply. I’m going to run two panels in series connected parallel to two other panels in series....I’m going with the MPP 24 V hybrid unit that Will recommends.... waiting for my batteries to arrive but I’m building a 200ah 24v Battery using prismatic cells and a daily BMS

Hi all I am installing 4-160 W 12v solar panels on my van that will charge either a 12 V 400ah or 24 V 200ah battery (depending on how I configure the batteries) Leaning towards the MPP 24 V hybrid solar charge controller inverter. It seems to be the best Value and all in one solution for the...

Ok now that we have identified that the price I was looking at was too high (Thank you Ghostwriter) Im still in need of guidance in regards to the question of 12v vs 24v and the bms thanks

Thanks

Hi All Looking for some advice. I found these batteries on Alli express 4PCS NEW 3.2V 200ah The plan would be purchase eight and either make 2-12v 200ah (400ah) total batteries or 1-24v 200ah battery using the either 2-12v or 1-24v Daly bms. i’m leaning towards going for the 24 V option it...
