What charge rate for the flat LiFe packs? - RC-Monster Forums

lincpimp · **What charge rate for the flat LiFe packs? -** 11.17.2009, 06:55 PM

Just bought one of these: http://www.hobbycity.com/hobbycity/s...C_LiFePo4_Pack

And was wondering what rate I could charge it at? I am guessing it should handle 2c fine, and I am not sure if my 1210I will do more than 2c rates anyways. The charger is good for 180 watts, so 4c would be about the max on 2s.

Just wondering...

You could ask the experts......>>>>>MA. I'm pretty sure Jason would love to hear from you

lutach I'm sure the MA guys love you too.

scarletboa · 11.17.2009, 07:11 PM

according to MA, you can charge at 15c....

Is there anything special about these?

sikeston34m · 11.17.2009, 07:36 PM

It says you can charge at 5C. That's 22.5 amps.

I just got some of these myself. My charger won't go 5C either, but it will go 10 amps.

I charged them at 10 amps and they didn't seem to mind at all.

i bought the exact same pack and will be charging them at 10 amps with my 1210i.

they look like theyre gonna be some sick batteries!

excited to get them

I gave a first run review in the Lifepo4 thread.

I have the same charger as you and use an Equinox balancer. My balancer can only handle up to 6 amps...so what balancer are you using to be able to handle 10amps?

MetalMan · 11.17.2009, 10:43 PM

LBA10 here (x2 for up to 12s), which is also made to interface with the 1210i. The Equinox is pretty much the older Hyperion LBA6 balancer.

Is there a real need to balance these? 2s with decent cells usually stay in balance pretty well? I had planned to not draw them very hard, 2 stock brushed motors and low gearing. Mainly bought the pack as LiFe really does not need a lvc.

t-maxxracer32 · 11.18.2009, 02:39 AM

since these are in a 2p setup wouldnt you need to balance it?

i could understand not balancing 1p but idk

lincpimp · 11.18.2009, 02:53 AM

The 2p cells will not benifit from balancing, as that only affects the series wired cells (or cell pairs in a 2p config). Hopefully the cells are matched well, and I will not be drawing them very hard. We will see, I will give them a test and keep track of the 1st few cycles.
