similiar except using different voltage batteries, and the question remains just how high can you go? But i guess a full 12v battery has a voltage difference when jump starting a dead one. so yea same thing

i mean i understand what you're saying in theory but its not like lighting flammable gas and boom! There is progression of heat build up. Sure u cant safely connect it then leave. But IF you're there while its connected you can literally feel the battery for heat, If i t starts to get hot due to...

Been trying different setups so far 0 heat from the cell being charged.. and it charges incredibly fast like within 3mins. Its really awesome ive gotten more heat from the cells from running medium loads.. This a hidden secret?

well i got this from google. so i know it can be done safely.. "A battery can be charged safely at high voltages as long as the battery is not fully charged. These higher voltages allow the battery to be charged faster. But if you want to leave the battery on the charger to keep it topped off...

hmmm.. i think its totally possible ive been testing it on 1s 1p packs connecting to 3s 2p 11.1v pack in parallel. you can just disconnect it when the smaller pack gets to 4.1vs and its fine just dont leave it there. im wondering if i can connect a 36v pack to 1s 1p? lol how high can you go?

Can use a higher voltage battery pack to charge a lower one until the lower is full(carefully monitoring)? Let's say i have a 48v full(54.6v) battery pack and i want to charge a empty(30v) 36v pack. i connect them in parallel and monitor the voltage of the lower one until its almost full(41.0v...

There is this red box or cube that has been coming on my display incidentally while my rear motor been having some reverberations while riding anyone know what it means?

hmmm interesting.. on appearance alone the battery pack seems just fine. it wont charge to full on either of the wires that are stand alone there's 2 black and 2 red that stand alone. im guess since they most likely are both connected to the same point on the bms or board. that might explain it...

yes 3 times. and tried on two batteries. its the most bizarre thing

i blew out the original port by touching the probes together while trying to check voltage. it vaporized a probe and part of the charging port. the battery wont charge to full unless i use the output ports it charges to 58.8v not sure if bms or my smart charger is stopping it at that point. but...

i thought it could be bms issue but why did it start happening exactly when i blew out the charging port? also i have a second battery and the same thing is happening this is totally wtf. not to mention the day i went out and got it soaked is the day it charged back to 58.8v. lol multimeter...

battery looks like this and charging port

i have a dual motor 52v scooter. the battery pack has 4 connections. 2 just wires and 2 xt60 connected to the controllers. I accidently touch the prongs on the multimeter while checking the charging port and it blew the gx16 port up. i ordered a new port and installed it. but since then it will...

I recently received my carbo after a 2 month wait. Excitedly I built it only to find out it won't power on. I thought maybe the battery was completely dead. I charged it overnight. Still won't power. Then randomly it powered on in the afternoon. After riding for 3 minutes it shut down...

anyone swap out the controller/motor? Im thinking about it but not sure which ones would be compatible with this bike..?

thats awesome i wasnt aware they had new color displays. does it fix the 40kph limit? did you have to pay for it? how much

yea ive seen this one and others that seem kinda similiar but havent been able to find the air-2 specifically. reconbikes.com has an air-II but its in korea. thanks tho

I live in NYC I've seen this bike twice now but I can't it anywhere online. Sorry for flash reflection on photo. Can anyone identify it/ where to get/ specs?
