    I have been watching this video on how to repair the main battery:


    I want to try and do this myself, I am on a tight budget, I have no experience. Has anyone followed the steps he did in the video and is it accurate everything he says?

    I would need to get one of those chargers to do the resistance test and restoring capacity. Is the one he used in his video any good? Is there a cheaper one I can use?

    Any help would be appreciated.

    This is a very good video for the do-it-yourselfer. The only item you might not be able to purchase NEW is that specific hobby charger.

    I don't care if it is new or not , at least if it can get the job done. But the one he used was priced $75+ for doing 4 batteries at a time. Maybe there is a better model you know of? I would like something cheaper than that , time is not an issue for me.

    If you want to save more money, skip the charger altogether.

    Can be a waste of time/money.

    If you are simply replacing one module because it is shorted out, get it close in voltage, take the afternoon to replace it and move on.

    Other portions of your battery will fail in the (hopefully not near?) future. Just play whack a mole and replace them as they fail of needed.
    Quick. Easy. Rather than spending days charging and discharging.

    Did your battery already fail in some way.

    Also be sure to use an inch-pound torque wrench to properly secure each nut. Over/under tightening is bad. Very bad.

    The car hasn't been used for months. Came back with the dreaded triangle symbol and a P08A0 error code. Now it won't even start up any more.The 12v was recently replaced. So likely I think the HV needs some recharging,

    A Meanwell power supply that could charge the whole battery at once for around $100. Charge it up overnight.

    Wow.
    You realize you are abusing the return policy if you use it, and then return it, right?

    You really shouldn't do that.

    It is just poor form.

    Remind me not to sell stuff to you.
