    Updated Battery setup.

    HA! Thats fun, I was using 3 full modules in two 14S of Bolt Batteries. I actually own a Bolt EV that is being repurchased by Chevy. After the recall I reached out the BH and asked what they could do to help me considering the batteries are in my house, they accepted their return due to the...

    Updated Battery setup.

    Yes I did not mess with a top balance honestly. I likely should have but my situation was slightly rushed. I could in theory go back and easily fix that problem, but I am trying with a balancer first to see if it can fix that for me. Thank you so much for the feedback I will try to update...

    Daly BMS Balancing

    Yea that would be amazing! Just would need a 16S

    Daly BMS Balancing

    Does anyone know where to get a female plug that would match up to the Daly BMS so you don't have to run all new leads to each cell.

    Updated Battery setup.

    Hey everyone, Just wanted to share my updated setup that replaced the Bolt batteries from Battery Hookup. This is using their new module Lifepo4 Modules. Let me know if you have any questions!

    price too low? too good to be true?

    I figure I would add this here vs making a new thread. Is this too cheap? https://www.amazon.com/gp/product/B09G2TRDYQ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1

    New Bolt EV Batteries and no BMS, one year observations.

    After speaking with battery hookup the Bolt batteries will be going back to them. I have ordered replacement batteries from them going to build 4 100amp hour packs from their lifepo4 modules that are new in combo with a Daly 100amp BMS for each pack. I will be posting a build as well as a...

    17S BMS for LiFePO4?

    Thank you for the help!

    17S BMS for LiFePO4?

    Yes so my Bulk would be 58.4V and float would be 56V I believe for full charge. I think for future proofing if I needed to expand the pack staying 16S would be smarter.

    17S BMS for LiFePO4?

    Yea I'm starting to realize that. I don't know how often I would fully charge the battery anyway, so it may be mute point. If it gets fully charged only 1/3 to 1/2 of the year does it really make any difference, it is still going to last nearly 10 years to 80% I would think.

    17S BMS for LiFePO4?

    So my charge controller can only charge to 58.4V that is 100% SoC for this chemistry 3.65V in 16S. So I'll get some 2000 cycles charging to full every time. So I want to only charge to about 90% to increase the battery life. 90% SoC is about ~3.44V for this chemistry, which means if I am...

    17S BMS for LiFePO4?

    I think I should clarify. The LV5048 has a max charging voltage of 58.4V. If I use a 16S that means each cell would be at 3.65V which is fully charged. I don't want to fully charge the cells, I plan to use about 90% of the useful capacity. So by adding a 17th cell that puts me at ~3.44V with...

    17S BMS for LiFePO4?

    I can't seem to find a good solution to this problem, so perhaps it does not exist. For my application it would be helpful to find a good 17S BMS as my control a MPP LV5048 can charge up to 58.4V which is the max ideal voltage anyway for each cell. To keep long life and max out the battery...

    New Bolt EV Batteries and no BMS, one year observations.

    All modules will be replaced based upon the paper work they sent(which I received), with the new chemistry giving 8% more capacity. As for gas or electric, I hate gas but "free" is "free" more importantly it is costing Chevy money. I'd much rather they had bought back my car, I'm still working...
