AM assuming the battery manufacturer told you, you can wire the batteries in series??. what bms type is inside?. the avg lithium battery doesn't like being wired in series. until recently that jbd claimed to release a bms that has that capability, though they are yet to release the science...

some cells in yout felicity bank are probablly out of balance. this is 7 months after any update?. felicity has a 5yr no questions asked waranty. simply take it back to the felicity dealer and they will fix the issue

Yes, observed this as well..had to replace a damaged bms due to my carelessness..and the replacement bms didn't have the soc % voltage isssh. i use same phone for all my jk bmses, so the issue is hardware based on the bms itself, not software.... there shud be a way to update the firmware on...

Since the trigger voltage is low, a high delta ensures balancing only happens when necessary. User can set 0.01v instead

Strange case. Try setting the cell cutoff/lvd voltage to 3v x nos of cells and upper cutoff/hvd to 3.45v x nos of cells on ur inverter. Then set same on bms 2.9v and 3.5v. Set balance trigger delta to be 0.02v and start voltage 3.3v

My jk bms shipped with the temperature leads unplugged. I inadvertently forgot to plug them while building a pack, and just realized it after i have shipped the pack out . My question is, would the bms work ok without the temperature leads? I would be able to have access to the pack in a month...

Same issue here, how did you resolve this Edit; realized i was logged into the standalone daly balancer, and not the BMS. Corrected the error and was able to set the SoC ok

am i missing something?. why not buy the original cheap jk bms standalone ON switch?..less than 5 dollars

the case is a custom built metal case, bms is JK-B1A20S15P I spliced and extended the on switch cable by about 10 inches. by Bluetooth device, you mean mobile phone running the jk bms app?..if yes..then sometimes the phone goes out of range, as its a slightly big apartment built with brick and...

So observed something on a new jk bms.the red led light on the power switch goes off after a while...and when this happens, am unable to see the bms on bluetooth, till i press the button once again...and it turns on. But it goes off again under 45mins. Is this a normal behaviour?. Also why does...

The cell temps stay a cool 32 deg C.hence why i suspect the issue may have to do with how i extended the P cable . I only added a 7inch extension using 35mm cable to the P cable and nothing to the B cable. Could this be an issue?

Same experience, my 150amps jk bms mosfet overtemp warning comes on when charging at 60amps AC

IMO, nothing special...just get a 200amps 4s daly or jk bms with Bluetooth and replace

Just a general jk bms question.. my bms didn't come with neg and pos cables. is there a limit to what length of cable, I can use on the bms? presently I have 35mm 7 inch and 9 inch for the p & b ports, I recall the OEM cables on some jk bms models are only 3 inch or so, hence why am wondering...

what size of helicoil is ok for normal eve 280ah terminal? edit @Skypower could you post the link of where you bought yours
