I went the Andy Kirby route for my first build and used power tool batteries, Milwaukee specifically. Their high output batteries can do a little over 1500w each and charge up to 20.1v. 3x M18 6AH batteries in series gets me a 60.3v pack. If you have the space for 2 strings of 3 batteries it can do 3kw continuous without any issue. And charging is way faster than a standard 52v 13AH, even with the quicker 3A charger. Considering my 36/48v controller only as 61v capacitors I’m maxed out in that kit. It also saves a bunch of $ since i can just used two M18’s for my wife’s ebike. The real downside is the extra space taken up by the casing of the packs, but they sure are rugged so youre less likely to have a fire after a crash.

This is very accurate, im a RC enthusiast and I use all the way up to 6S lipo. You can dump extremely high current without significant damage or heat provided you don't over discharge them just like lithium iron. They do explode though if they are impacted heavily. Never charge unattended...... ever!

Hey thanks for that Steve,that’s given me some ideas about a project I have in mind,good man!👍👌

Too many new ideas, my mind's going overdrive now, keep it up!

Great content. Love the techy stuff especially with batteries. Just started my own solar panel and battery storage system

Nice vidéo Dude,yes lipos are fucking dangerous,never charge them in the house unsupervised...and get à smoke detector..Regret that lipos have little Mah capacity but for amps its unbeatable...can't wait to see your monster build..well done on the safety aspect..

this was so cool, Great Work!

If you want i can show you what i have done to wire my batteries in to my latest BMS You will need a "6s JST-XH Parallel Balance Lead Harness" cut three off with as much lead as you can then solder these to the balance leads (in sequence) of your BMS. I can do you a little vid . Been making my own mid drives since 2012.

Yeah I'm going to try this been waiting for really

first time here! good content. subscribed🤗

I flew drones. 15pacs a day. For years. Best system by far. If one pac fails dont have to replace whole batery. There made to drain.. charger's show each cell condition. And charge faster. Good choice of charger brother 👊👊💪💪 your friends giving you good advice. 👊👊💪💪 if ever see a cell not balancing right? Through away. It will get worse and explode one day charging or full throttle for to long.. and trust me. Scary shit! Always charge outside!!

Great content. Love the techy stuff especially with batteries. Just started my own solar panel and battery storage system. And like you,I’m sh1t scared of electricity ⚡️ 😂

I have the same setup but 16ah. 18s lipo Capable of over 200A. Using on a bbs02 with external 3000w controller. Works amazing and the batteries doesn't even get warm even though the controller pulls max 60A

Thanks dude a VERY interesting video.

Great idea mate!

cant wait to see to see these weapons in action

Which battery’s are you using please. Great vlog.

Great fun but you got to be careful because a lot of controllers have 63 volt capacitors and just going slightly above their maximum can blow them.

Thanks Steve...👍

Subbed up Steve. been watching a few of your videos now, I like your ideas. I'm looking to make an e-bike system that will give me miles over the hill - the Pennine hills where I live, (up North) - I want range. I'm looking to get the range, carrying my and my camping gear to extend my years of bike touring, any ideas?

Eh up, steve. Have you considered using the car battery jumper packs for power?

This guy just said it reminds me of making bombs or something haha😂 madnesss 👍🏻👍🏻👌🏻

3 makita 18v 6 ah batterys, 250w hub, 30+ mph, i made a rectangle box you just slot into and fittted to bottle rack bolts. put a low voltage circuit in else you,ll kill em, pcb on ebays for like 5 quid, i set it to 45v and it cuts out. plus easy to charge on makita charger. these are the best batterys ive used so far, they sag the least and really give you power till the end.

Thanks for the video I learnt alot

Hi I’m looking at this set up on a 3kw hub ….. any ideas on distance not being to aggressive on throttle

hi hi steve. suggest you pop those big bad boys in a lipo fire-proof bag or 'bat-box' when you have them in your backpack!!

I have a few 60v 4Ag greenworks batteries that i use for various ride-on projects. These things give me low range but they make the thing go FAST. Its quite the fun.

I modify Makita powertool battery holders to take contacts and then fit three in series to a nylon base. I then get 60v 9Ah and my fat bike does 10 miles on that. Costs me less than £100.

you should look in to running them together with a VESC (y)

Can i connect 2 48 volt batterys togither to make more power for my bike as i only have the 1 48v and im looking to buy another to wire them togither to make more power and to last longer is it possable?

You are the god of ebike content

I love your videos thank you for making them

Could i say . Get some XT150's for your end power connections , they are safer than spades with nuts

Aup mate can this be done with scooter batteries I have two 36v batteries could I pear them and make 72v 🧐🤔🙈🦚

Tape up the lose ends bro 🤜👍

You're brave mate, I'm alright with plumbing, but electrics terrifies me. Great video showing us the whole process and sharing the KZfaq love with your local tech shop. Genuine nice fella. I'm just bouncing back between your channel and Andy's realising I have 4 years of catching up to do! Plenty of interesting material and knowledge shared too, nice one

Off to the garage .

Get a body warmer , gaffa tape and you’ll have a good fancy dress outfit lol😂

hi, looks like i have the same desk legs as you but what desk top do you have? im looking for a new one.

i wonder if u could connect some lf280k's to a ebike

Im using six 11.1v lipos in series. They pack a punch but balance charging them is time consuming. I like the lightweight of the pack.

“Booooom” 😂

First morning Steve

You did not mention what voltage motor you are using.

do you have a link for the charger ? from Brisbane Queensland Australia

Tops u are man ♂️ you can do any thing you think of gosh some skill to have i love e bikes scooters exc but bigger and faster bike I want one day I suffer with lungs 🫁 but they help me a lot getting around and Ur just over all amazing man big up from 🇮🇪💯

Can you change them all at the same time

How about anything with a 5k-8k fardriver controller project?

What is your direct contact info please regarding battery pack an ur mate doing them.?

Votol, Fardriver are good options for controllers

I have a 4 x 100watt charger that can charge 4 of the 6s lipos in just over an hour

im very lazy and use them spring loaded cable connectors , i pour hot glue inside it for more security and water proofing

How long does the battery last?

My controller is rated for 72v. But its only 60a. Will 66.6v of lipos work? Or do lipos require more amps?

i bet big clives workstation also looks that cluttered

Try flipsky 75200 controller.

I would love to have the b... To do it make one

If you look at the wattage your 6 or 8 gauge wires could handle, you are wasting a lot of energy transferred into heat 100ax50v 5000watts, look on car audio what wire sizes you should be using for such wattage

Egg rider display, small though. ASI controller

Hi there mate so iv seen few vids of dyu jetson bolt and windgoo lil e bikes and there few farat modified 1 but no links for nothing i bought a windgoo for lil brother larst year is standead and original battery is 36v 6.6ah 350 watt hub moter he dose not use no moore and have been searching for months doing research and i cant find no battery that of roght size and gd quality i have controler/ trigger throttle it can take up 2 72v battery problem is there only 36 10ah available but my self im looking for 60v but min i need 30ah plz help me out mate do you have contact details i. Uk London and not fused about speed or id chage hub moter biger watt is ah and battery size as wona keep it clean and basic dont wont it look like iv done nothing 2 it but need it as a dail go 2 and will be traveiing long distances my 1 dose not have pedals i have there pegs

Be careful of over discharge as lipos do not have over discharge protection. You have to set minimum voltage in the controller.

get the wago clips man, isolate all the bare ends and only have one wire exposed at the time. It is good that you went to the shop because you have no clue what you are doing.

There’s a reason why E-Bike manufacturers don’t use Lipo….. You’re insane to sit on a bike with Lipo that close to your body.

Damn! That took a long time to explain a simple set up and no footage of the bike he's using it on.

Has anyone actually done this yet? Stuck on a battery on my build 😫😫😫

72v is 20s, u only have 18s

What's a good place to buy lipos in the us?

LifePie4 bapperies serm grood as hospitlles use. Trest me, si good. ;) saventyto volt erty amp grate 4 long travel many miles like monroe :) -yer walca

I would put a bac 4000 From greenline engineering they made me up the kit that I could run my QS205 hub motor 5T check out chriscrosingwires on KZfaq he has a light pole monster that does 100 miles an hour

So.. 3x 6000mah batteries in series is still only 6000mah, but higher voltage?

Too many new ideas, my mind's going overdrive now, keep it up!
