has anyone actually received the 310's yet?

Lol no I was asking what primary voltage to do my calc with because three is a diff between 12' and 13 volts lol. I was just saying I only drained then to 17 percent. I can calculate used capacity and add 17 percent

so from what i am reading here.. you are running them all Parallel ... thus 1680 watts at 16 volts equals 100 amps... why not run all 4 in series? you suggested a 100/50 controller.. if you run them in series you have 80 volts tops and only 12 amps... no need for anything above a 10g wire...

Dead on the money. Plus or minus 44 watts they ran out at 230ah or 2900wh so they passed

ok either i am not searching for the right thing or just a Moron lol... I have a magnum inverter in my RV... 50 amp charge from it when hooked up to shore power..... I want to install 800W of solar with a controller and 700ah of Lith when i am hooked up to shore power or start my Gen...

yes it seems this was something i did not expect when i ordered them,,, i just researched it and they say theryte is a new one that works in parallel but of coarse thats not the one i have...... now have to monitor them close to make sure they dont over charge until such time as i can rplace...

i built 3 , 4 cell battery... independently they are 13.3 to 13.5 volts measured from pos to neg out on bms ... the min it parallel them all together i have 12.4 volts.... is this normal....

never mind...

I need a bms recommendation that will allow me to parallel 3 12v 4 cell 230 ah batteries I have all 3 on Daly and they are not working properly they will not shut off to stop over charger..

my thor is a newer and has the ability to set the charge and float levels as well as cutoff level in the charge profile...

i built 3 230 ah batteries for my RV.. 230 ah cells 150A Daly BMS i had 2 installed the coach and everything seemed fine..... now with the 3rd installed things have gone weird today one cell in the middle battery over charged to 4.7 volts and swelled really bad... the BMS was set to...

I guess I will find out how durable as usual when you don't get what you order from alibaba getting any refund is non existent...

yes alibaba sucks and thier buyer protection is worthless.... they wont even follow up on the refund..... i had a similar prob with this same company... shipped me cells without the studs i requested.... they offered partial refund which i never got and alibaba claims was sent... but i never...

i found some listed in my area.. the back plate says they are 10 years old... how much performance will they have lost? has anyone purchased panels on Alibaba? they seem to have good prices there as well......?

i just built my first battery... i have 4 230ah eve cells.. i top balanced to 3.65 i have a DALY 150 amp 4 cell BMS........ the app seems very accurate on voltage and watts..... once it had it all activated i ran a small inverter with a hair dryer on low.... the BMS said it held...

wonder if there is a way to get them across the border in Bham.. lol

these are the new EVE 230ah cells with that they called welded studs.... instead of welding a stud on they weld a threaded nutplate on..... you can see its welded......and appears to be alloy and not aluminum ... i org ordered welded studs and got these ugh... i hope they work... the supplier...

i would also be concerned at the heat breaking down your epdm rv roof
