[NSRCA-discussion] Li Po charging and balancing

[Fred Huber]

Small Lipos... I am using a Hobbico "Quick Field Charger Mark II."  It does NiCd/NiMh 1 cell to 8 cell (maybe more cells... thats as high as I have used it for)  And 1 to 3 cell LiPo.  It can charge 2 packs at a time.  0.2 to 2 amp charge rates.  Self detects cell count, you have to cet the cell type and charge rate.  Very handy to have.

I use an Astro Blinkey ballancer and I'm finding that CHECKING ballance once every 5 to 10 charges is adequate for may packs which do not get doischarged faster than 8C, with an average flight time of 15 min.  Faster discharge rate would be more likely to cause imballance.

Relatively inexpensive charger and ballancer.    Giving good service.

Astro has an adapter available for the ballancer for cell types it does not directly fit. The ballancer is good for 2 to 6 cell packs.

Large LiPos I'm using the Astro 109 (and I ought to send for the update chip...)

  All

  I'm getting deeper into the electrics and am looking for a decent charger and balacer for "small" winter projects. I don't plan on getting any bigger than 2100mAh batteries.

  I found some interesting looking stuff at Central ...the Yuntong AC/DC charger and balancer. Very well priced and with enough capability to do the job.

  Is there any experience with these produtcs out there?

  Does the balancer include TP connector?

  Is there anything else that may be a better solution?

  Any help will be greatly appreciated.

  Thanks
  Colin
