DIY 600W POWERBANK FOR YOUR MACBOOK OR LAPTOP

[@ericklein5097]

Should have used the IP2368, its half the price or less and its a buck boost that works so well with a 4S pack. My channel is pretty much dedicated to USB PD and lithium ion...especially the buck boost boards.

I love this case . I built a speaker with it

[@LuisRodriguez-xf9lv]

Exelent Tool. very good battery pack. is it possible to add a lithium state of charge meter for 4s? just to know how the battery bank is going

[@stevenc22]

Literally doing a video adding a meter 👍

i think rather then the 4x5 the single holders might of work out better or at least the 2 4x5 then a row of the single holders to get the max length

[@1981dasimpson]

that looks like a prtection circuit and not a bms unless the balance chips on on the bottom i think i would of gone with 2x 4sx8p packs and then joined the pos and ned and had the rectangle 25a bms on them

[@stevenc22]

In the end i went with 2 4 x 8 holders.

also instead of the wall adapter controlling the voltage and current it would be better to use a buck boost converter this way you can use a larger votage range for charging be it solar laptop charger or even maybe a little hydro turbine you just pin to the bank and let run in a stream ok shtf stuff but hey why not build for any senorio

Sadly I can not find this PCB or any similar one. Any chance you could ship one to Germany?

[@stevenc22]

I gave a link to the pcb in the description. If you can't get ahold of that pcb, buy a 12v car adapter and steal the pcb from in there. m.aliexpress.com/item/4001091236146.html?spm=a2g0n.detail.0.0.6dc42499azMEnl&gps-id=platformRecommendH5&scm=1007.18499.139690.0&scm_id=1007.18499.139690.0&scm-url=1007.18499.139690.0&pvid=230f7775-d24d-4a8d-8a18-7cc5e061805b&_t=gps-id%3AplatformRecommendH5%2Cscm-url%3A1007.18499.139690.0%2Cpvid%3A230f7775-d24d-4a8d-8a18-7cc5e061805b%2Ctpp_buckets%3A668%230%23131923%2367_668%23808%235965%23331_668%23888%233325%233_668%232846%238113%23662_668%232717%237566%23817__668%233374%2315176%23426&browser_id=af316464fca447f58019d2232a94f1b5&aff_trace_key=&aff_platform=msite&m_page_id=jfq5f7u8nq0caukg173df69303a21d807658209ebe&gclid=&_imgsrc_=ae01.alicdn.com%2Fkf%2FH53ca121e7ef44b008572f5fddee7199b3.jpg_640x640Q90.jpg_.webp

[@stevenc22]

Like 5 pounds
