Next time I go out in the boat I will grab a battery with the interal BMS with Bluetooth. Shows amp draw... maybe then I can figure out what is going on.
While discharging the batteries stay spot on within .012V per cell in each battery. It wasn't until I started charging that is goes out of whack.
I started with 2 12v battery on a Renogy Rover 12v system, and then you can guess what happened from there. I assume I will upgrade again in the...
So a bit of a follow up, I have rewired the Plug in the front of the boat, I spliced aka Crimped with a wire lug, short 8awg cables on the negative and positive cable that are 4awg that run from battery. I am not 100% sure but one wire thread from the positive looked awful close to the negative...
I have a 24V system 2s3P 100ah 12v lifp04, I have been having 2 battery that go into a cell overvolt and then it throws a pack overvolt. what would be possible causes for a cell overvolt other than manufacturer defect? Could I be sending too many amps and it overvolt the batteriers? I have a...
I'll get 2 more ordered then. Its odd how when I had 2s2p a single balancer worked and everything was great. So what would be the best way to wire this up with 3 balancers? Remove the interconnects but I don't know how to wire that in, Or keep the interconnects and just strait across each...
Honestly I don't remember, it was working fine for a while, then I believe I bumped the speed to max and it shut down, it was really really windy so I was fighting the wind the whole time. Seems like the surge to High is what caused it to shut down, It did it on another lake when I was using...
(the BMS balancer start voltage is set at 3400 with delta to balance at 10 )
So I want to charge to say 13.8V and hold them until they all equalize then send them to full?
Just so I grasp what you are saying in my own terms
Weize battery says it has a 100A continuous discharge capacity, I have 3 of these batteries. Now I am concerned, 2 batteries I installed in my solar setup 1 I used for trolling motor on my boat. I took my boat out a week ago and the trolling motor stopped, I assumed I forgot to charge the...
I had the positive on the incoming positive, common between the 2 parallel banks, and negative on outgoing negative. All I know is it was working with 4 battery.. no I didn't have the 2nd interconnect on the positive to negative on the second series. But it was working...
Hello everyone I am new to this group.
So I am looking at the 24v PowMr Solar Hybrid Inverter 3000W
Does anyone have a sugestion for a 24v solar charger inverter all in one that actually has built in bluetooth/wireless? Besides renogy 48v? everything I see requires a dongle like that Powmr or...
Will said he wasn't impressed he didn't say they were JUNK, they did everything they were supposed to do. Build quality was his Concern. He also stated the cells were different but they were not pouch cells.
watch the Video if you need to recall
I got 8 of these panels deilvered and opened them the next day sure enough the first box I opened. Anyone have any experience with them sending out replacement panes etc? The email I received from them was less than useful. How patently must I wait? a week? a month? a year...
I think I might use 8 ecoworthy 195w panels I have the ecoworthy mount with renogy 100w panels currently. I can install a second matching mount attached to the first one. Roughly 1600 w. I am drawing up a schematic for ideas.
Is it possible for someone make a Shunt that communicates like a BMS to correct SOC on these stupid LifePo4 batteries? Just tossing it out there.. I can't imagine someone hasn't thought of it already.. yet I cannot seem to fine one. I bought a PowMr 3k-24v and the SOC is over 30% off from the...
I have a System with 2S3P Lifep04 Batteries 4 have Bluetooth 2 do not. They are all purchased within 6 months of each other.
I have been having a problem with over volt on one side of my series connection, So i lowered my charge profile until I figure out a working solution.
Currently I am...
So i have 4 100AH Lifepo4 Batteries 2 JavaEnegy and 2 Weize, (1 of the JavaEnegy and 1 Weize in Parallel) connected in series for 24V.
So i was looking at the BMS data on the JavaEnegy batteries tonight and realized they are having Charge and Discharge Over-Temp faults.
The batteries are in a...
I will need to look up solar assistant, no idea what that is.
2s2p was my plan with the batteries.
Those 100w panels are like $65 each, main reason is I have ecoworthy mounting system and a second one would hook right up to the end, would fit all 10 panels nicely. 1kw for about $700, other...
Just got done doing that, I charged them 2 days at 12.8v and then lowered them a bit then charged at 14.4v for 24 hours.
I hooked them up yesterday, today after draining overnight to 70% when I got full charge I looked and one parallel bank of the 2 in series is 14.2v the other is 13.6v. I was...
I had removed them to and charged each separately, then paralleled them and charged them to 13.6v Sunday Night, then Tuesday night I ran them to 14.4V and let them sit until yesterday around noon. Each battery was measuring 14.4V and the 4 Bluetooth battery were within .012v on each cell at...
So I decided to try and test the Battery, I used a Kill-a-Watt and ran 2 Halogen 500w bulbs, said it was pulling 810W at 119v. So roughly 75Amps DC is what I calculater I used said. I let it run for 20 minutes and zero problems.
So my guess is not the BMS tripping from amp draw, now I am curious...
