Hello folks,
I have a thunder power tp-610c charger with an older version 5.1 firmware that doesn't have the LiFe function to charge Life batteries.
I was wondering if I could charge LiFe batteries using the A123 function on this charger instead.
I just want to make sure if it is ok, otherwise I will have to send in the charger to do a firmware upgrade.

All the newer tp-610c with firmware version later than 5.1 Has the LiFe function, but does not have the A123 function.

Also, what is the chemistry composition of A123 batteries?
Is it lithium phosphate like the LiFe batteries as well?

Thanks

Tam

Yes you can. A123 are LiFe batteries.

A123 is a brand (A123 Racing) and a packaging option (round cans) for LiFePo4 chemistry batteries.
So all A123 are LiFe, but not all LiFe are A123.

Thanks fellas for the quick and informative response.
I have a few more questions.
Can I charge a LiFe battery pack, say a 2s pack, at double it's current rating? Like charge it at 2c or 4c?

I have a small receiver pack that is 200mah and I wanted to charge it at 0.4 Amp. Is it safe to do this?
Also, do they need a break-in period like lipo, where I need to charge them at half a C for a few cycles before using them normally?

Do they swell up if over discharge like lipo?

Thanks again folks.

Bottom line - you can charge any LiFePO4 with the A123 setting on a charger. I always balance charge mine too. I figure they put a balance tap there for a reason.
