These Batteries are amazing, But they have a Propietary software Lock. This Project liberates them from this lock and allows you to use them in any way you see fit. https://www.pcbway.com/project/shareproject/Okai_ES200G_36v_Scooter_Battery_Controller_project_By_jag35.html
Hi Heju. I got a question. I am new to this scooters. I have some Akai scooters that they are lock, they have this battery, 13INR19/66-5 48V16Ah- 768Wh. If I get this controller this will I still have to get "Motor Brushless Controller with Rainproof LCD Display"? or this modification will by pass the lock. sorry I am new to this word.
Dude you're amazing! Thank you for your open source approach to business, it's greatly appreciated =)
My ES200G dongle no longer works. Any ideas what may have happened and how to fix it . Appreciate the help.
You said FTDA cable did you mean FTDI. an Amazon link would be helpful.
Been having communication problems with the arduino nano, not keeping the battery alive on heavy loads. Now I have purchased the pro board to see if that was the issue..
(puzzling is the nano runs the program but doesn't work to keep the battery on when hooked up? I'm also running a step down as well)…Still cuts out
Jason, why are you using an Arduino when it is so easy to make a LED blink, the circuit is very simple. do a search for LED flasher on youtube. the other board you're using is called a buck converter, it can lower the voltage from you supply. mike
Surface or through-hole mounted components can be attached to PCBs in the USA. No need to go to China especially during these turbulent times.
im trying to buy these but cant place an order
Hold on, can i charge the battery using the Dongle as well? via the bigger port?, i connected the battery to the charger using the dongle, i did see the charger (charger with the XT90) go red and the dongle light up but i dont want to break anything LOL
Hi, Would this PCB also work with the ES-400 battery ? If yes, would it also be the battery blue wire to be connected to the board ?
I have 4 scooter batteries and purchased 3 dongles, two X1 dongles and one X4 dongle. Problem is none of the dongles are waking up my batteries. I started out by using a X1 dongle with my 42V 1.8A charger to charge each battery separately and on the first battery the dongle overheated and shut down and no longer works. I used the other X1 dongle to charge all 4 batteries being careful to monitor the process to be sure that there would not be another overheating issue and there wasn’t! So did I receive a defective dongle?
However, none of the batteries woke from hybernation via the dongle! I was able to wake two of the batteries by jumping the batter using two wires from my charger to the positive, negative of the small connector of the battery. The other two will not wake!
Anyone have any ideas?
Are you going to sell any more of those??
Will these be back in stock at JAG35?
how do i charge multiple scooter batteries im making a 72v ebike do i need multiple batteries chargers or can i use one but it will take longer ? new to all this
Great Stuff! I already ordered x1 Dongle from Jag35, think i want to make a x2 version at home since i have arduinos and buck converters laying around… Just wondering where can i find the round battery connector end or what is it called? It looks like the one used in the video may be harvested, but im sure if you are making and selling dongles, there has to be a source for them? thanks!
I'm using the scooter battery as a part of my boosted board and the PCB works while charging the battery but not when the battery is connected to my hoverboard hove motor. Any tips??
