One day when i was trying to charge a small capacity 2s 7.4volt 800 mah battery with it , i saw leds go brown and within second i observed magic smoke.
When i opened to see what happened to my surprise 2 of the 3 smd 6leg chip burned. I am helpless at the moment as i couldnt find these chips . This was 3-4 months back now i dont know how to charge my new 3s as its showing 11.73 volts.
What should i do ?

save that for later, i know that u love doing stuff like that but desperate times need desperate measures.... get an intelligent charger :D really good investment and suits all ur battery needs! faster charge rates etc etc...

its a glorified charger controller,

basically, it connects to a specific charger and tells it what to charge it as and battery position.

Thanks
would a clone from www.robu.in okay to buy ?
Please consider that i will only charge <1500 mah batteries.

BUT
My friend had a clone and the battery voltage displays were off by almost 0.1- 0.3 Volts.
If thats okay; you may buy it

Was it a new or old / second hand

okay but my budget permits for a clone only . I wil upgrade the clone's voltage detection area with high quality low tolerance resistor and try to upgrade the firmware.

That's Russian.
I love that language and am trying to learn it.( only caught up with the alphabets yet)

поезд любитель- Train lover  ;D
аэрофлот- Aeroflot Airlines
ТУ 144 кабины- Tu 144
( My profile image is the cockpit of a aeroflot Tu -144 SST)

But thats a flopped concord copy.

NOT a FLOPPED concorde copy.
read about it and then say.

prabal276

By the time the TU 144 entered sercvice; the hype for sst flight was long gone because of the crashes of the concorde. Thats why the tupolev 144 did not gain much popularity. It was used by NASA to train astronauts  and ussr to transport cargo long after the death of the concorde.
there are even a lot of structural doffrences. The 144 looks much more beautiful.

Same problem with me. My B3AC charger's IC burned after a sudden spark when plugged to AC mains. Does this charger has a lifespan of only 5-6 months ?
