Kim, Love your work. The Lipos are the way. I "Gangsta" charge them, using a Meanwell power supply which I had shipped from WA to Queensland. I run 8 x 5S 5000mA Turnigy, and charge them empty to full in around 45 minutes. Can't want to see more progress on your machine.

I've posted videos of the Turnigy's in action: http://www.endless-sphere.com/forums/viewtopic.php?f=12&t=12875

My Turnigy 8 x 5S 5000mA (as 10S4P pack) are brilliant ! I have them permanently paralleled (after lurking forever, and PM'ing people for help) and charge them "Pirate" (on a Meanwell RSP-1000-48). I run a fuel gauge when using them, to monitor balance and remaining charge. I use BM6 when...

I get it. Great idea ! This will solve one of the problems with using shunts ... as I see it, shunts effectively reduce the the resistance in the circuit as they come on ... which pulls more current from the power supply just when less is needed ! I can't wait to here more. MJH

Instead of high-jacking two other threads (Turnigy, and 1010B+ series charging) ... I've quoted and replied here ... Rc-groups has a circuit to balance LIPO's that doesn't involve shunting. The thread is here: http://www.rcgroups.com/forums/showthread.php?t=270580 It is very similar to...

How long are you thinking it will take to charge a 20S 10P pack, with 10A from a 1010B+ ? I have a 10S 4P pack, and don't want to live with the 1010B+ (too long to charge, and way too long to balance). I've arranged a CC-CV power supply for 26A at 48V (Meanwell RSP-1000-48). These are superb...

Good news from HobbyKing. Posted it back to them. Almost immediately they emailed me they'd received it ... and today I get an email that a new one has been dispatched to me. Very impressed :D The Lipo addiction is growing (I feel the need ...)

Thanks. Yes I thought about an easy fix ... but looking through the vent, everything is charred and black. I have looked for other similar symptoms, and I found a story about a PCB trace to the large capacitor not holding its weight, and the capacitor giving way. Actually, its not all bad. I...

Purchased a bit over a month ago, while running a cycle on a single 5A Turnigy Lipo (5S), and during the discharge on its first cycle, something gave way in the 1010B+ and it started smoking. Smelled the smoke, ran and unplugged it ! Now it is dead. :cry: All of a sudden, this NewB (me) has...

... and that is why I defer to people who know what they're talking about. Thank you. :) The thing that worries me ... is leaving the Bike/Go-Kart switched on - with batteries connected. One of my sons is bound to do this. I'm assuming the worst - perhaps it is even left for a week or even...

Corrected circuit ... fixing problems with delay for the pre-charge ... and adding in working values for resistors, and transistor.

I have created the circuit below, but as I am an electronics beginner, I could certainly do with some helpful comments, suggestions, or criticism. I'm hoping the circuit will work like this: 1. At the start, the battery is physically totally disconnected. 2. Press the "start" button...

liveforphysics, I'd be keen on 10s 20Ah packs, or even a number of 10Ah packs. For the next project, you understand. Regards, MJH

A very informative, excellent thread. Hopefully the right one for me to make my first post. The good news - based on my lurking research here, my 9 x 5000maH 5S Turnigy packs turned up yesterday from Hobby City. 8 of them perfectly balanced. One not so good, with one cell around 100mV low...
