  • Post in thread: Ok you win... Cell imbalance

    I need to research how to do that with the JBD BMS
  • Post in thread: Eeek help! Eve280amp Batterys melted! Is my bms faulty or what happened here ?

    If one battery is charging off the other battery... It means that you've either not properly balanced them or that You have more resistance on one of your battery banks or wiring causing a mismatch Alternatively you could have one pack that has a smaller capacity I have a 460 amp hour, 2P4S...
  • Post in thread: Trying to decide on a mini split - help?

    I run a 12000 BTU in my RV... 293 square feet). I wish I had done a pair of 9000 BTU... Added a 5000 BTU window unit.. stays reasonably cool now...
  • Post in thread: Aims Power inverter shut off will not turn back on

    Another interesting thing is a little earlier today My wife powered up the microwave and it died as soon as she tried to start it... No breakers blue or anything but I shut off the breaker to the microwave and turn it back on she tried it again same thing... But eventually it just started...
  • Post in thread: X4 lv6548 in 120/240 can I still charge off of 120 volt input?

    Yeah I have the original model as well mine is an LV 6548 not an LV 6548 v
  • Post in thread: How much faster is top balancing cells individually?

    It's still coffee time my friend. I'll admit I was a little offended... But like I say no hard feelings. And some root beer and a tobaccy pipe does sound good
  • Post in thread: Overkill BMS vs multimeter

    good point as well. not to mention the cable might be under sized
  • Post in thread: Recharge time

    So I have 4 Duracell gc2 wet acid batteries... There's six volts configured to 12 volts I've had quite a few gray days lately and as a result I've had to use my generator in the morning to charge up the batteries and potentially in the evening as well The inverter charger can do up to 100 amps...
  • Post in thread: Epever MPPT charger confused by Renogy battery inactivity?

    That might be one of the stupidest things I've ever heard What a dumb feature
  • Post in thread: 65A on a 100A busbar, still too hot!

    so lots of things to look at... if cabling is undersized or doesnt have appropriate air flow(bundles or wire) it will heat up... as it heats up the resistance increases, which leads to more heat... its a run away cycle some fuses and breakers are big causes of heat... same issue as above...
  • Post in thread: Electric/propane water heater?

    I have been thinking, propane is a great way to heat water... But if I have excess solar power, which happens a lot in the winter, I might want to heat with solar... But I can't seem to find a water heater that can do this... Anyone aware of anything that would work?
  • Post in thread: JBD 4S 200A BMS - heater function?

    So is there a setting or do they automatically turn on heat pads(if attached)?
  • Post in thread: How do I connect battery banks that are in 2 different locations (distances) to the one source & keep them evenly balanced

    I would not worry about the difference... What will happen is that while charging, the battery that is closer to the charge source will charge slightly faster... And the battery that is further away will charge slightly slower And then once you are first battery is fully charged all the current...
  • Post in thread: Ok you win... Cell imbalance

    My pattern of use varies with the seasons of course... But generally speaking I almost always reach a full charge during the day... But I'm oftentimes under load so meaning even once I hit a full charge the battery management system will shut off charge turn on charge shut off charge turn on...
  • Post in thread: Fast approaching the start of my off-grid house solar build... How to deal with local government?

    I know I have the support of our mayor... But I also know that it's a little out of my lane to be writing those as I simply vote on planning and zoning... But I imagine I could look at it in a way where I caughtify the planning and zoning for solar and alternative energy installs
  • Post in thread: my 540 watt setup will this work ok

    Bu But still a safe ball park figure
  • Post in thread: 24v heating pads on 4s battery packs?

    Actually just talked to the manufacturer... They say that it does have a high temperature shut off switch built in He also made sure to mention that it's pretty important to have this properly adhered to the battery otherwise the heat transfer will not be enough and it could potentially burn...
