Hi, a year or so ago we bought a batch of Eve280 A grade matched and batched cells from one of the recommended suppliers here. Made 3 X 24v batteries connected as a single 840ah bank Did it all by the book, top balanced, noalox, etc etc and they have been trouble free appart from Battery A...

Hi, just noticed today that I had an overcurrent alert for 3.362v on a bank of 8 x lf280k cells. Any idea as to what's going on here? Thanks in advance

Have had the big EVE 280 bank running in the boat for 8 months now and still haven't been able to figure out myself how to get the Victron 702 reading the same as the JBD BMS app. I get up in the morning, look at the Victron and it reads batts at 72% but reality is, according to JBD app 54% I...

Hi, on our boat we have 840ah @ 24v of LFP 2.5kw of solar A 24v victron 5000/120amp multiplus And a 7kva Genset for rainy days which this year have been numerous. Taken offline several years ago is a 24v victron skylla 80amp charge only that I want to connect up to fully load the Genset when in...

Apparently heat and possibly fires "could" be caused if connections become loose say from vibration for example. As our bank is on a boat in a space near the engine room and prone to vibration it has me wondering. If everything is nicely torqued down and running fine why couldn't I use wicking...

Have 3 seperate eve 280 24v batts installed. All matched and batched All top balanced All cell terminals cleaned, noaloxed and torqued All cables the same size. 2 batteries seem identical or near enough But one (A) draws less when under load and has more go in when under charge and the imbalance...

Hi and a happy new year to all We are finallyr readyfor installation of our 3 X 24v eve 280 house bank A question, looking at the pic, if the batts are fully charged shouldn't the cell bars be showing more full, like my scribbled first bar and the bright green like in to 100% semi circle? As I...

Hi all Have 3 x 280ah @ 24v batts ready to get connected All matched and batched A Grade Amy cells Each with its own 200 amp JBD BMS and bluetooth One BMS turned up without the module and its being sent, but xmas delays means it aint here yet and wont be for a while and I need to get these...

First of 3 x 24v batts being made with A grade matched and batched Eve 280k. Tried to top balance with a 30v 10a power supply but that would have taken a decade or more so put them back in 24v bank, hooked up the JBD BMS and after a small dipole tweak, got the spare Victron Skylla TG 24v 50a to...

I know in the perfect world top balancing is essential But in this not so perfect world I have been sent a dud bench power supply Due to covid and based on how long the last one took to arrive ( I bought inside Australia) I may not see a replacement until next year. Our home (boat) has rapidly...

Had my 3 JBD JBD-AP20S003S-P20S-200AB BMSturn up yesterday, description and manual is in this thread https://diysolarforum.com/threads/jbd-bms-have-found-similar-here-but-not-this-model.25881/ Just a little bit of trouble with the wiring instructions, I THINK I know what it means but just need...

Hi, Cells will be here soon for 3 X 8s with 3 BMS and am wondering .......will I need to have 3 apps loaded -1 for each BMS or does the same app control all 3? Never used one before, just wanting to get my ducks in a row in advance.

Anyone tried one? 1 day left on sale @ 50% off I need one for top balancing either this or longwei at more than double the coin https://www.aliexpress.com/item/1005003247639012.html?spm=a2g0o.cart.0.0.70493c00OGnIbx&mp=1

My desperately needed batts are apparently in transit as of yesterday but I have zero additional info as of yet Me thinks I am going to have to buy some second hand AGM to get me through the wait. Maersk Diverts Ships After Ningbo Terminal Shuts For COVID...

As mentioned in another post our 880ah @ 24v of AGM is failing after 5 years of full time use. 840ah @ 24v worth of EVE have been paid for and hopefully will soon be on their way. In the meantime, trying to keep what we have operational. Method for the last few weeks is to wake up at 5am, batts...

I haven't seen lanolin discussed here as protection for freshly cleaned alloy terminals I could pay $25 for a tiny tube of ox gard or, as I already have 5 litres of Lanox MX4 on board could I not use that? It sounds to me that it will do the same Thoughts? We already have dozens of tubes of...

I know you do but don't really understand why. I have been speaking to somone using drop in Lifepo4 saying they don't need to change settings because BMS cuts off charge at a set point and that makes sense but why then, is changing charge settings to get rid of float mentioned so often? Without...

Have googled the model number and images and have found similar discussed on here but not the same Can somone who is knowledgeable comment on this please? JBD-AP20S003S-P20S-200A-B-U This was suggested by Amy Wan as a BMS for each battery on a proposed 3 X 280ah @ 24v for a combined 840ah...

It is time to pull the trigger and order 24 x EVE 280 from Amy to build the 840ah 8S3P battery The question she has just asked is which BMS do I want and frankly, I have no idea. Research on here suggests I don't want a Daly Which leaves JBD and Chargery being offered JBD seems most popular on...

I think* I have decided on these GBS cells for our new 600ah house bank build but I am unsure as to why they have twice as many terminals as others. Anything to be concerned about or is it simply a 1 is good , 2 is better thing? * I keep flopping between a 600ah bank of these and an 840ah bank...

Has anyone done a sticky or similar comparing same sized batteries with other brands on a bang for buck scale? Eg: Winston, Calb, Sinopoly, GBS I guess these would be considered tier 1 companies? I see the cycles are different on them. Do you think it may be conservative of some and over...

Hi We are full time cruisers on a boat that is set up to be away from shore power indefinitely. When we got her the batteries and inverter were dead and on the perhaps false assumption that it was sized correctly, simply replaced with a bit more. 8 batteries replaced 6 and 5000w inverter...

New here but not totally unfamiliar with the concept of solar any batteries but far from knowledgeable. Have been cruising full time on the Queensland coast in a converted prawn trawler for 5 years now with a predominantly 240v boat powered by 2.5kw of solar, a midnite classic 150mppt, a...
