    Spring replacement?

    The issues is that it's easy to get bent spindles. Hasn't happened to me yet fortunately but it's a common issue.

    Spring replacement?

    It's actually more than my opinion. https://mechanicalelements.com/torsion-axles-in-tandem-or-triple/?srsltid=AfmBOooNR2MpPb5YZT3JaiTlqBP8YYkZm8w6gdmcn7URavNfw1KfUu2f Synopsys of the article: There is a good reason why torsion axles get their spindles bent frequently. When one wheel goes...

    Spring replacement?

    Stick with leaf springs. Have you looked at eTrailer.com? I bought replacement springs for my travel trailer there.

    Spring replacement?

    I have torsion axles on my boat trailer. Wish I had leaf spring setup. ONly advantage of torsion axles is letting the trailer sit lower...everything else is a con.

    Time to replace tires?

    18 year old tires! You got lucky!

    Replacing my power block

    Just add another of the same power block.

    LiFePO Batteries ???

    Remind me again which DC to DC converter you have? As we discussed beginning of 2024, I bought the Victron 50A XS model. It has been outstanding and you can program in any current you want as well as the voltage it kicks in at which likely would solve your idle issues.

    LiFePO Batteries ???

    3 months ago I bought a small 50A LiTime battery to power my trailer's electric over hydraulic brakes when I tow it with my Rivian. My Rivian can't supply enough current so I just use the battery in the bed to power the brakes during the short drive between the storage place and the launch ramp...

    LiFePO Batteries ???

    You are talking about an external BMS system. The internal BMS in these batteries have a standby current of 1mA.

    LiFePO Batteries ???

    How much current can it put out? I wouldn't go over 50% to a DC to DC converter. Probably should start a new thread though. What starter battery do you own?

    LiFePO Batteries ???

    Per month!

    LiFePO Batteries ???

    The BMS did its job..it turned off the battery when either the total voltage went below a limit or one of the cells went below the limit. The problem is, the cells keep self discharging even after the BMS turns off so the cells continued to self discharge over winter until they got to a point...

    LiFePO Batteries ???

    Here are the 140AH battery specs

    LiFePO Batteries ???

    That won't do it. One or more cells are toast from over discharge.

    LiFePO Batteries ???

    I went on there...there is no mention at all of 2C charging. It does however say the BMS can handle 100A but they recommend 20A.

    LiFePO Batteries ???

    Show the link where it says that.

    LiFePO Batteries ???

    You can’t charge at 2C. The BMS doesn’t allow it!

    LiFePO Batteries ???

    LOL...The people you talked to didn't make the battery. They hired a supplier in China and plastered their name on it. Believe it or not, charging a LiFePO4 battery is not rocket science. You charge at a bulk rate(constant current) until it hits and absorption voltage(typically around 14.2V)...

    LiFePO Batteries ???

    Actually, a thin cable would be the best...it would limit the current. You are just trying to hit it with a high enough voltage to trigger the BMS. Your biggest issue is if its a really low cell that is causing the issue. If it is, you may not be able to recover. I helped a friend of a friend...

    LiFePO Batteries ???

    LOL...A123 batteries are still LiFePO4 battery cells and they are the EXACT same chemistry as all LiFePO4 batteries!
