A123 vs. Turnigy (LiPo) vs. Zippy (LiFePo4) vs. you name it

With shipping I don't think HK can beat these for the li ion low price.

Super fast shipping and low shipping prices to USA.

We are testing these and others like them.

So far so good. Waiting for a cell to go weak so I can try and blow it up but none are going weak.

This stuff is for real ? You really can buy new li ion for lower prices than HK and they show up with all good cells ?

These look like something I'd be interested in using as 4 of these would easily replace the 4 12V SLA batteries Im using right now. Keep us updated on your tests with these batteries and do you use an ordinary LifePo4 charger with them?

Ebike and lawnmower double duty testing !

I hooked balance wires to them so they could be charged with the Hyperion 1420 and they were balance charged the first 40 cycles.

The balance wires are hooked to cell log meters now and they are being charged without balancing with the Hyperion 1420 and are watched closely while charging.

I want to see how many cycles they will do before needing balancing.

So far so good with these batteries.

Etriker how are you using these baateries on your bike ? I guess the model you have dosn't have a bms ?

2 in series for 24v 20ah on a Currie kit on a Trek. 35 amp stock controller 450w brushed motor.

Last ride about 10 miles off road used about 6 ah.

I like to pedal too.

No, mine do not have the balancers like these do.

Mine are the ones without balancers like these.

I like to use a Watts up meter and lipo alarms or cell logs for discharging. Hyperion 1420 for charging.

They shipped them very fast for a cheap price and packed them very nice.
