I have come to request the wisdom of the battery builders
Currently planning my next build: I’ve got a 12s4p p42a Evo build that I want to upgrade the battery in, to a 12s8p. I’m also in the process of building a 12s4p DD vanguard.
My current plan is to reconfigure the battery from the Evo to fit the vanguard enclosure and have a fresh 12s8p built for the Evo – is this the best plan of action? should I just add more cells to the existing Evo battery to make it 12s8p? I figured mixing new and old cells would be less than ideal
I mean, that’s basically a new pack but I’d still go with your plan. Breaking down the pack to add more cells just isn’t worth the trouble. It’s so much work and wrought w danger.
What needs to happen to the 4p to put it into the other board?
going from an eboosted evo SS enclosure to an eboosted vanguard 12s3p, so 1 less pack, and a very different configuration. basically has to be redone as I understand it. person who is building my new battery is doing the reconfig as well
Hello, a friend had got a new Hurricaine and basically his maiden voyage was at esk8 con. Several times the power would just cut off. He had some other battery with him. Swapped it out and all was good. He ended up getting a new battery from Meepo and no problems. I offered to take a look at the battery/ esc for him hoping to see something obvious. I opened her up I did not see anything yet. I did not take it apart apart just enough for a basic visual. Battery is reading 44.7V. Still have to hookup a meter and twist it a bit to see if voltage changes. Here are some pics.
Looks like the whole thing may be welded with copper. Balance wires overlap and are thin as shit and main leads are
No that would actually be one less cell in each parallel group. Also a lot of work. He’s basically going to have to tear the whole pack apart in any case.
Is the person doing the work a member of the forum?
sorry, yeah, as you can see I’m not super familiar with the terms haha. and no I don’t think they’re on the forum - it’s a local friend of mine… but yeah, it’s gonna be a lot of work
All good bro. I’d suggest you read the intro to batteries thread. It’s not super long and will give you a cursory understanding of the foundational stuff. Good place to start:
Does anyone have any suggestions to test this Hurricane battery? I did not check voltage of the individual P groups yet. I was hoping not to have to take it further apart but it looks like I have to. I was thinking if P groups check out and all welds look good maybe just replace the BMS and bypass it. Uploading: 20220529_152312.jpg…
Thank you! I will give it a go. I’ll actually wrap thin wire around a pin with some heatshrink and wrap other end of the wire to the meter probe end and still use a lighted magnify glass lol. Yes dont want sparks.
