Glad i bought the external packs with both my 10X. Me and my girlfriend get crazy range now with 46Ah. And they installed it. Best thing is to ask at the time of purchase so both batteries are fresh.
Other scenario: my bike has a built in batterie. so every time i want to charge it, i need to carry the entire bike to my flat. therefore i want a 2nd one, that i can use first and recharge easily. if i happen to need more than that power, i can switch to the internal battery on the run.
I have a zero 10x with an external battery that doubles my AH. Is it possible to keep the batteries connected in parallel and charging both batteries through one charge port? I ask because sometimes I only have one hour to charge up a bit and I don’t want to deal with unplugging both batteries, charging the external battery for 30 mins and then the internal for 30 mins in order to keep the volts the same.

Hey, I know this is an old video but I hope maybe I'll get an answer, I want to increase the range in my ninebot g30p, I want to build a external battery with the same or more Ah than the original battery(15.5ah), will I be able to just paralel them by the xt60 y splitter and use/charge them just by doing that?

Hi there. So I just want to add some more capacity to my Apollo Pro which is 52v 23ah. I think I would be happy with another 10Ah of capacity. If I add the solid state switch to the arrangement then I would only need to plug my scooter to one port and charge both is that correct?
We do not have 10Ah. The 18Ah is going for a good promotion right now. You do not need the switch because they are both 52V. And yes you can charge them at the same time.

Hi FalconPev, 1 question. I have spare Zero 10x 60v spare battery and planning to make it as range battery. My question is: why in your video there is only 1 port connector on external battery and the internal has 2? Can you please help. My scooter is Zero10x
our battery has 2 ports, maybe shown in video only one port, but its really 2 ports. but in actual fact, it depends on the size of the connectors. If the connector is a larger size that can handle the current, then one port is all that is needed.
@@timcarranza1146 like in the video the plugs will be labelled. If you need any specific plug you can let us know and we will use those plugs on your battery.
Yes you can. You can run them together, or separately, by connecting/disconnecting the wires to/from the parallel connector. If you connect them both and try to charge the batteries it may not work because the BMS in each battery pack will conflict with each other.. You will have to charge the battery separately. Or remove the BMS from one of the two battery packs for the charging to work.

Can I use solid state switch to utilize batteries with different voltages? My scenario is to use lower voltage external battery which trades speed for range. 72V internal battery plus 60V long range battery and switch for 60V battery when 72V is depleted.
Batteries have to be same voltage. The solid state allows for different capacities to be connected. So like if you have a 52V18Ah and you want to connect to with a 52V23Ah... That would work. But 60 and 72 won't be possible.

Please I hope you charged them separately. Because you are charging both batteries at a different rate of charge. That will cause problems if you charged them parallel connected.
Hey so what will happen if I install the external battery first on the scooter before charging? I won't use or ride the scooter yet. Then after installing it, charge both the internal and external batteries. Is this bad or it doesn't really matter since I won't ride the scooter until they are both fully charged anyway?
You'll be fine if you do it that way. Just make certain you plug everything in correctly and when you do charge them you, they are fully charged and you'll be good to go.
“A spark is good” Uhhhh an anti spark XT90S is like $2. Not using one screams cheap component selection. Why destroy your connectors with constant electrical arcing? It will raise the resistance of your connector

@@FalconpevSg I know your plugs are labeled but my plugs on my battery and my controllers are not labeled so does it not matter which ones I plug into.
@@basincut100 once you open up your scooter, you'll see the wires FROM your controllers and your battery coming out..... thats how you'll know which cable connects to the labelled connectors that is provided to you. :/ Example, their cable is labeled INTERNAL CONTROLLER 1 AND INTERNAL CONTROLLER 2....so what you should do is look for your 2x controllers (hence the word INTERNAL). Thats your 2 x silver boxes. Look at the cables coming out of it. Connect it from there...
Connecting in parallel is a dangerous method,it can burn both of your batteries or degrade them prematurely,one discharging the other.The safest method is to extend the cable from the controller,tonaply a 6 pin swich(ON-OFF-ON) and to use separately the batteries,also charging separately.If y realky want to connect in parallel without switch,y need 2 new batteries with the same voltage,the same brand and the same capacity,fully charged and use the same distance of cable for connecting to controller and charger.Otherwise,y will have errors of charging batteries.

@@FalconpevSg ok perfect and do i need to charge batteries separately when they are paralel ? i ordered the cables allready as soon as i saw your video
You cannot discharge and charge with DC current at the same time. Your explanation makes no sense. The correct answer is if your batteries are at different voltages the current when connected in parallel may be quite high for a short period of time. The battery discharging can likely handle this but the battery taking in that current…well nearly every lithium ion has a charge rate that is a fraction of their discharge rate. The P42A can discharge at 45A (below 80 Celsius) and is likely capable of bursting higher than that without negative consequences (the data sheets often give two life cycle numbers for a slow charge/discharge and a fast charge/discharge so keep that in mind) but the max fast charge rate of the 42A is 8.4A or 2C. You’ll see that even the best power cells from Samsung/Sony/LG typically have a limit of 2C when charging but discharging rates can be 10C. So one battery might be discharging at a rate that is close to or within manufacturers spec but that means the lower voltage battery will be FIVE time over the safe charging rate. Voltage differences of less than a volt typically only give very short bursts of current before declining to a much smaller rate but over one volt and you can see some very large balancing currents that last for more than 10 seconds depending on the size of the batteries. So besides voltage difference there are two other factors. Internal resistance and battery size can increase the current rate and length of time if the pack has low resistance and is very large in capacity. This can be simulated by taking two high IR cells 1V apart and measuring the current flow vs two low IR power cells 1V apart and measuring the current flow. The low IR cells have the ability to balance each other faster albeit at higher currents. The larger the pack the longer it will take them to balance which means more time it will take for the voltage delta to change from 1V to 0.9V
We understand what you are trying to explain in detail but when explaining to lay person there is no way that explanation wouldn’t fly over the head of most people. What we are trying to say is essentially the same, but communication needs to be simplified so people can understand.
Yes, your message is too long and I was feel like going to sleep. God did tell me that what you said (all of it) is incorrect.. As for the Molicel P42A battery cell handling 45A discharge and 8A charging is incorrect it will cook those eggs for good. Their test rating is fraud. At that rate those cells will go bad very quickly, less than a month. The Samsung 40T cells on the other hand are the opposite, they handle 45 to 50A discharge and last much longer than that. It can handle 8+A charging as well. For the Molicel P42A the safe charging is at 1.5A, that is one and half amp. The owner that runs this company will run into serious trouble cause a lot of high ranking criminals are getting scammed by these batteries. You also need to be careful on the Samsung 40T cells as almost all of them floating in the public market are fake, but performs better than the P42A in charging.

Example, their cable is labeled INTERNAL CONTROLLER 1 AND INTERNAL CONTROLLER 2....so what you should do is look for your 2x controllers (hence the word INTERNAL). Thats your 2 x silver boxes. Look at the cables coming out of it. Connect it from there...
Connecting in parallel is a dangerous method,it can burn both of your batteries or degrade them prematurely,one discharging the other.The safest method is to extend the cable from the controller,tonaply a 6 pin swich(ON-OFF-ON) and to use separately the batteries,also charging separately.If y realky want to connect in parallel without switch,y need 2 new batteries with the same voltage,the same brand and the same capacity,fully charged and use the same distance of cable for connecting to controller and charger.Otherwise,y will have errors of charging batteries.
Is it possible to order a bigger battery from you guys and use as an external? Maybe like the same one the Zero 11x comes with?
As long as we have a bag that fits
@@FalconpevSg Do you know why my battery cuts out at about 39.5 volts? (it used to run the motor right down to below 36 volts). I would be grateful for your advice.
@@nicholasmorrill4711 battery cells are getting old and cannot hold the same charge anymore
@@FalconpevSg I know that because it only charges up to about 40.5 now but should'nt that mean that it should still run out to the same level as before? (about 35.5).
@@nicholasmorrill4711 no the fact that it doesn’t charges up to full capacity means that the discharge rate is susceptible too. Voltage is a good indicator but it doesnt tell the actual charge capacity of the cell.
can i use paralel connection for 2 batteries with only 1 controller or i need 2 controllers ?
Doesn’t matter the number of controllers. You can use 2 batteries or 3 batteries for one controller
@@FalconpevSg ok perfect and do i need to charge batteries separately when they are paralel ? i ordered the cables allready as soon as i saw your video
@@techgeek2994 you can charge them together
@@FalconpevSg on which port original or it doesnt matter ? thanks for your help
@@techgeek2994 if they are in parallel it doesn’t matter
If I have a60 volt battery and I add a 48 volt battery is it okay?
Only if your controller can take it
If I have 60volt controller’s? It is okay or should I add another 2 48volt controller’s?
Thank you for your help 🙌🏻
@@maxshara yes sure. But why do you want to do that?
@@FalconpevSg because I I’m adding a48 volt battery to my 60 volt scooter
Spark is bad, it's very bad, it will damage the connector and you will have to change it at some point. Just use spark protected XT 60-90S connectors.
Yea but the voltage rating is much lower. They cannot reach 60A
why are sparks bad?
You cannot discharge and charge with DC current at the same time. Your explanation makes no sense.
The correct answer is if your batteries are at different voltages the current when connected in parallel may be quite high for a short period of time. The battery discharging can likely handle this but the battery taking in that current…well nearly every lithium ion has a charge rate that is a fraction of their discharge rate. The P42A can discharge at 45A (below 80 Celsius) and is likely capable of bursting higher than that without negative consequences (the data sheets often give two life cycle numbers for a slow charge/discharge and a fast charge/discharge so keep that in mind) but the max fast charge rate of the 42A is 8.4A or 2C. You’ll see that even the best power cells from Samsung/Sony/LG typically have a limit of 2C when charging but discharging rates can be 10C.
So one battery might be discharging at a rate that is close to or within manufacturers spec but that means the lower voltage battery will be FIVE time over the safe charging rate.
Voltage differences of less than a volt typically only give very short bursts of current before declining to a much smaller rate but over one volt and you can see some very large balancing currents that last for more than 10 seconds depending on the size of the batteries. So besides voltage difference there are two other factors. Internal resistance and battery size can increase the current rate and length of time if the pack has low resistance and is very large in capacity.
This can be simulated by taking two high IR cells 1V apart and measuring the current flow vs two low IR power cells 1V apart and measuring the current flow. The low IR cells have the ability to balance each other faster albeit at higher currents. The larger the pack the longer it will take them to balance which means more time it will take for the voltage delta to change from 1V to 0.9V
Thank you for the detailed explanation.
We understand what you are trying to explain in detail but when explaining to lay person there is no way that explanation wouldn’t fly over the head of most people. What we are trying to say is essentially the same, but communication needs to be simplified so people can understand.
Yes, your message is too long and I was feel like going to sleep. God did tell me that what you said (all of it) is incorrect.. As for the Molicel P42A battery cell handling 45A discharge and 8A charging is incorrect it will cook those eggs for good. Their test rating is fraud. At that rate those cells will go bad very quickly, less than a month. The Samsung 40T cells on the other hand are the opposite, they handle 45 to 50A discharge and last much longer than that. It can handle 8+A charging as well. For the Molicel P42A the safe charging is at 1.5A, that is one and half amp. The owner that runs this company will run into serious trouble cause a lot of high ranking criminals are getting scammed by these batteries. You also need to be careful on the Samsung 40T cells as almost all of them floating in the public market are fake, but performs better than the P42A in charging.
