    Rogue cell? Or not? Lifepo4

    Will do thanks.

    Rogue cell? Or not? Lifepo4

    I hadn't thought of the 2. Mmmm

    Rogue cell? Or not? Lifepo4

    Here's a vid. When the clouds come over it drops as the battery bank is under load. But why this poor little lifepo4 cell is suffering so much? Or should I say appears to be.

    Rogue cell? Or not? Lifepo4

    I have a 16s Lifepo4 bank. Overkill Solar B.M.S. Sunny day with clouds, battery bank is full so I turned on a 2kw blow heater to use the free energy from the sun. One of the cells (On the app), the one that seems to go up and down more in voltage than the others generally and is always the one...

    JBD error "FET Software Locked"

    Using the Xiaoxiang app I turned the charge and discharge function of the BMS off and on. This cleared the error in the Overkill solar app. I couldn't switch them off in the Overkill app prior to this.

    Looking for 48V Battery Charger

    I dont know what open and closed loops are. Id probably go with the simpler option and use a permanent voltage setpoint and current limit. Something that would draw enough amps from the generator up to around 80% SOC. If I forgot to switch off the generator the BMS should protect the bank. I'm...

    Looking for 48V Battery Charger

    Indeed I believe my output voltage isnt set high enough. It was set at 53.5v iirc, you can choose this when buying the unit. Id like it to be higher but I dont know how to program through the CAN bus. I can see where the 2 wires connect in but I'll have to look up the ins and outs of programing...

    Looking for 48V Battery Charger

    The output of the charger is probably limited to 50 amps. My generator wont be working at 80% probably less than 60% but its an old crank handle Lister/Peter so I'll go gently first to see how things develope.

    Looking for 48V Battery Charger

    I understand. I have wired the generator into the house now so I'm just about to crank the handle and start her up. Happy days. I have it wired straight to the battery but I'll send it through the BMS later for more fun! Yahoo! Thanks for all the info folks.

    Looking for 48V Battery Charger

    Brilliant, this makes sense regarding the sparking and connecting it up. The battery bank is only half charged. It's at 52.8v.

    Looking for 48V Battery Charger

    Ok this makes sense. I was connecting the charger to the battery permanently. I didn't expect to have to charge a capacitor like connecting an inverter. Can this sparking damage the charger?

    Looking for 48V Battery Charger

    I tested the wire from the charger to the battery with a clamp meter.

    Looking for 48V Battery Charger

    I'm sorry about the confusion, I tried to add a video showing the flashing light but it failed to load. The light is on the Vertive charger. I tested the DC output of the charger connected to the battery. It was supplying nearly 50 amps to the battery. Im not sure about a current limit. I think...

    Looking for 48V Battery Charger

    Well I hooked it up and gave it a go. When I connected the dc cables to the battery there was a spark and it kinda stuck to the terminal a bit. Like a short or charging caps on an inverter. This worried me a bit so I just plugged the 240v into it and it lit up. Then I checked the dc voltage. Its...

    Looking for 48V Battery Charger

    Theres a breaker on the generator, I suppose it would trip if it was under too much pressure.

    Looking for 48V Battery Charger

    I just got the R48-3000e3 from China. I want to power it with a diesel generator that is supposed to generate 4000 watts (5Kva) to charge a 16s Lifpo4 bank to 53.5 volts (80%) The R48-3000e3 is 3000 watts at 48 volts so I assumed I'd be running the generator at 80% except when I look at the...
