Hello All. Could you please help me to repair my icharger 3010B. Yesterday i used it for charging li-ion batteries. When i tried to measure internal resistance of li-ion cells charger shows string containing rectangles of display units and stopped working. Turning off and on does nothing. I...

Hi guys. Do you know what is the highest voltage that controller allows to use? And why dont you use 40152 cell. I assume that it will fit in deck spacer.

Damn BMS it turns off batteries when voltage became 23,0. 3.28 per cell. It is estimated for using with LiPo batteries and cutoff is to early. Cutoff worked at 30 km trip. The main problem is that i can't start charging it with icharger 3010b or with onboard charger. It doesn't start to charge...

Its strange but... I have charged batteries with icharger 3010b to 28.7 V and now iam trying to charge it with onboard charger to 29.5 but charging process stops just after ~ 1 minute and voltage is the same 28.7. Iam assumed that if i will turn onboard charger on it will charge batteries to its...

There is variable resistor on the charger board. But it has a glue drop on rotatable part. And i have no idea how to regulate because i can't start charger without controller and can't measure its voltage without batteries connected. It starts only when batteries and controller are connected to...

You are right. I have found that termination voltage on my iCharger 3010B for LiIo batteries is 4.10 V. So i should to charge pack to 28.7-29 V but not more. Onboard charger is estimated to charge LiPo batteries to 4.25 V per cell. Is it possible to drop down highest voltage by modification of...

I ride 20.62 km and its voltage became 25.3. So i can ride more. I think it can be ~25 km. I dont try to ride far away, i was tired of his long ride and try to finish it as soon as possible. But if i need to change this battery i will use 38140 LiFePo4 without balancer and i will use iCharger...

Hi guys. Now i know how did the esr tell me that he is ready to ride. He bliknk with all his leds at the same time. And the voltage is 29.8 It is ok because when i turned it off the voltage will brings down for ~ 0.2 Thank you guys for helping me.

Charger use a higher voltage because when it will turn off battery voltage goes down about 0.2 V. After few hours Lix batteries can be charged again for some mAh. Anyway guys who has hoverboard with lipo batteries by default tell me pls is it will stop to blinking when charges is complete or not?

I asked guys who really know what is going on with onboard charger and leds on the throttle lever. As far as i know charger always use little more voltage because when charger is turned off the battery voltage is going down. So charger turned off when voltage is about 4.24 V on cell.

I have hoverboard that was with lipo batteries by default. So charger should to stop charging when it is fully charged i think. Or BMS should to disconnect batteries. It doesn't start charging until the batteries will have specified voltage AFAICS.

I have only onboard ESR charger. And i dont know how it will show me that charging complete. Its just blinking with leds while the voltage is 29,7 and do nothing, maybe i should to wait a few minutes and it will turn off, but i afraid.

Guys, pls help What should i see when charging is complete? It is blinking with 3 led 1+2+3 and than turn off but summary voltage is 29,7 but it should be 29,5 I afraid of overcharging :-) Thanks a lot.

I've made this. I used 18650 5p7s with original goped BMS. I checked with voltmeter that every parallel group of cells after 1 hour of charge has the same voltage. And than pack battery. Now it is on charge. It took a lot of time (about 9 hours) to charge it successfully. I checked charge...

Thanks a lot, i have already saw this video. I thought about the conversion goped to Li-ion batteries. And i can use stock BMS with that batteries. But it is more expensive than 38120. Another plus of 38120 is easy assembling. Li-Ion batteries i should to solder carefully, it is not the problem...
