View Full Version : TP and UltraRC LiPo (3S1P, 11.1v) - SOLD
09-14-2006, 12:36 PM
I have standardized my e-flight power packs. So I have these packs that are not being used and are available.
Thunder Power 2100 mAh, 3cell 11.1v, 10C rated pack. Has seen light use in my Formosa. Pack reserve is good - providing 1980+ mAh discharge when tested on my Accucycle Elite. No plugs. Used, but a good pack for light-moderate use up to 15 amp. Not for a heavy amp draw application. $30 shipped
UltraRC 1000 mAh, 3cell 11.1v, 20C rated pack. A good little one that packs punch! A powerful little pack. Comes with built in circuit board that automatically balances cells when charging. No plugs. $30 shipped.
Note: shipping is INCLUDED in the prices posted.

Pack 1: Thunder Power, is a 2005 pack - original type; not a prolite. It is a good pack but I would not use it in a high 10C+ application. So I would limit it to a 10 to 15 amp setup.
Pack 2: UltraRC pack is excellent. Packs alot of punch (20C). Charge is between 920 and 1020 mAh. This pack has been occasionally used to haul the Formosa around for 15+ minutes at high power/speed feeding an AXI 2212. It is light enough to put into a foamy onto a AXI 2208/34 for some extreme power maneuvering.
I haven't used either pack very much. Maybe 10-15 times each.
The UltraRC pack looks like this:
""The function of the B.M.S. is to guarantee the voltage of each individual cell is "equalized" at 4.2 volts per cell. Once the voltage reaches 4.2 volts, the B.M.S. will "cut-off" the charging current. Two power connectors, not included, are required for assembly. ""

Can you post a pic of the TP pack? Thanks, Mike

I'm selling these because I have a bunch of old Kokam 1500 packs to use up and have standardized my battery mounting around the K1500's.
The thunder power looks exactly like this, except it doesn't have the balancing tap plug shown here.
