iChargers and the Maxpro Accelerator

Another interesting use of the Motor DRV function is to drive this 5-way 3S balance charge adapter from Maxpro:

Accelerator 3s
Specifications
1. Supports 3cells Li-Polymer batteries
2. Balance charge up to 5 sets at the same time without same pack capacity & cell voltage
3. Charge current: 1A / cell
4. Voltage detection precision: 10mV

The device is not yet available but if you want to track it then see this thread: http://www.rcgroups.com/forums/showt...770389&page=46

Also: Where can I buy some 106B/1010B balance adapter boards/cables?

Thanks!
Hello,
Nice questions!
Actually, the 106B with a USB port built-in to allow for easy plug-n-play firmware updates is under consideration. But there is no timeframe for it now, it will take time.
As for the balance board and cables, you may find help here: http://www.eheli.com.au/store/home.php, they design different balance boards and cables by themselves!

Regards,
Junsi

Hello Charles,
Thanks for your suggestion!
750 watts, awesome
We will expand the maximum capacity of our products step by step .We plan to develop chargers whose capacity falls within 500 watts !


Best regards,
Junsi

Hello badger-b,
We have made a test as what you set. Sorry to say that we didin't say anything wrong with the cycle mode ! Does your charger occur such odd thing occasionally or everytime when using the cycle mode?

Best regards,
Junsi

The only existing demand for 500-1000W chargers comes from A123 users since their packs can be safely charged at 20A or more. For those users, right now the best solution for such high power charging IMO is a Mastech CCCV power supply:

Mastech HY3010E-3 Dual 30V/10A (600W) - charge two A123 packs at the same time (up to 8s) or a single pack up to 15s at up to 10A or a single pack up to 8s at up to 20A (~USD$278)

Mastech HY5020E, Single 50V/20A (1000W) - charge a single A123 pack up to 13s at up to 20A (~USD$258)

You need to use an inline watt meter to monitor the mAh if you want that information and they need AC power, so to meet the requirement of running from a deep-cycle battery (bank!) you have to add a suitably rated inverter.

While not as convenient as a purpose-designed charger and not up to 20S @10A (but certainly capable of 10S @ 20A) the Mastech offer a fairly good solution for the power hounds

I still want to charge my 6S 10.000mah lipos at a full 1C. Missing some ~50W with todays 1010B, so >200W is on my wishlist

But, yes, a Mastech is probably the currently best option if you only fly A123s... A "2020B" could remedy both of those "painpoints".

Just my 2cents

Quite so . However but it would be a limited market IMO.

Consider that a theoretical 10s/20A/400W charger would draw about 42A @ 12V or 21A @ 24V. I think that a device rated for over 40A input current would be large and expensive so in all likelihood full power would only be available at 24V (even 21A input is quite hefty).

A minority of users have 24V sources so few would be able to access the full rated output power. And of course only a minority have the need at the moment.

As an A123 user, I am not denying that a 1020 or 2020 would be nice to have, but perhaps not the best target for developing volume sales.

I hope that any charger I will own, will have standard serial data available /accessible inside. Whether there will be module converting it into USB or not, is not important to me - I am afraid of common ground of charger power supply and PC, and I never ever run charger out of power supply if connected to PC by metalic wires.

- I have serial Bluetooth module inserted into chargers, which sends out charger data in simple SPP profile, and can connect easily with any notebook automaticaly (PC remembers connection and establishes it automaticaly after running LogView). Perhaps in the future, there will be applet for mobile phone or GPS navigation to use it at the field. I need simple serial data to use this. ( Junsi, what about price comparison of Rayson BTM-222 or BTM-112 SPP BT modules, versus price of USB conversion?)
- It would be usable for me to attach SD card into charger and time to time look at the charge graphs stored there. Solution is quite easy with serial data and simple atmel mcu, but I can not imagine simple solution driving USB host to do the same.

what about to develop an external "connectivity box" with all those BT, Raysons or what ever?

There is no developing, there are 3 wires directly from charger to module. Ground, power, and data out.. I do not believe in bluetooth so much to use also "Data in" for charger upgrade.
I know that 1010B currently do not send out the data, and connectivity is used only for upgrades. However, I think and hope that upgrades will not grow forever like with M$Windows, and once the development and bugfixes will finish, there will be no need for usb to use the charger at all.
