Hi everyone,
I have super soco TC for one year and everything is working as expected so far. I want to extend my TC's range if it is possible also acceleration and max speed too. I have checked forums and internet with a hope to find any tutorial or something like this how to build a soco battery but I couldn't find anything. As I'm completely noob to this topic (I don't understand the difference between volt/watt/amper yet) I want to ask a couple of questions.
1- As a complete noob should I try to my own build or it is better to buy an aftermarket battery?
2-I have found a dealer on Aliexpress he claims that they are selling a BMS which is compatible with the original battery and controller there isn't any need to crack or something (Price is ~80€). Could it be true? Does anyone here have some experience with such third party BMS?
3- Can I achieve better acceleration only with a BMS or should I replace also the main controller?
4- The same seller on Aliexpress has also batteries for TC and he told me I can use a 59.5AH (~145km price: 1430$ incl. shipment) battery in parallel with my original battery which lasts ~55km. Can be this true what he says? If yes Is there possibility that too much power damages my TC?
5- If I try to build a DIY battery, I should get all the necessary tools is it worth investing all of them such as spot welding machine etc.?
Selam yetisbey hayırlı olsun üyeliğin ben de senin gibi yeni sayılırım ortama ancak bir mühendis olarak cevaplayayım gerilim ve akım bilgin olmadan batarya üretmen çok zor bir iş yani elektrik elektronik hesap kitap işi önce bunları bilmek lazım. Ancak çok iyi bir tasarım ile pekala da yapılabilir yapanlar da var yok değil bu forumda da varİ kincisi üçüncü parti üretici bataryaları şans işi biraz hazırda yapılmışı var hesabı ancak dediğim gibi alanlar da bu konuda inanılmaz memnun değiller ancak bir arkadaşımız (bu forumdaki) çok memnun olduğunu belirtmiş. Bu arada 59,5 Ah tek batarya içinde bulunması oldukça zor bunu söyleyen firmayı iyice araştır bence.
I am in the same situation as you, I want to build my own using 21700 cells so I can gain space for a later upgrade, but only have basic knowledge.
I saw the same higher ah batteries as well, probably the same seller, and I also want to know if I would be able to use it without problems, and without damaging the moto.
Maybe one of our gurus here can help ☺️
Guys, building a DIY battery requires strong electronic knowledge and a lot of care.
If you don't know the difference between volts, amperes or watts... don't start your DIY project.
The original battery is 17s12p, this mean it's big and not cheap. A genuine Samsung/LG/Sanyo cell costs ~4 €, so only the batteries may cost you ~800€ (you have 204).
Adding the BMS will jump over €1000.
Anyway if you have a good source of genuine Lithium-Ion batteries (18650 or 21700) you can start builing your battery. But read carefully this forum, the second battery should have the same capacity as original in order to work in paralel.
The best option I think is to build a higher capacity (like 40Ah or 50Ah) battery and install a separate voltmetter (because without original BMS the IC/Display will not be able to read the battery status and will show 0% and blinking) and use it until it's depleted (means no less than 20%) then switch to original battery to get home. But first make some calculation (geometry) to see if both batteries will fit the compartiment.
Hi,
thank you for your answer but there’s one point which is not clear for me.

this seller mean that I can use the bms like the original one, if it is true I can build a battery which has doubled capacity in compare to the original one and I can use it alone. Regarding the seller the display also has to work. I imagine that if one can build two DIY batteries wlth above mentioned bms range of tc can be up to 250km and with a working display. That would be awsome 🙂
for me acceleration is also very important. Sometimes in the traffic it is necessary to act quickly if you are motorcycle driver and soco is very bad about it...

Yeah that so true that you have to know what yu are doing affecting during procedure...may be better to get some advice from professinals...
@selcukkucuk I second this. There's enough energy stored in 1 pack to seriously ruin your life.
