I'm really interested in this cells as now I'm racing in ISTC modified brushless class. Normally we use 6 cells NiMh with 4.0 or 5 cells with 3.5. Since IFMAR will approve Lipo/Life in next Ifmar world. I have some questions before purchase this LIFE cells.
- Does charging procedure same as LiPO? just different voltage peak limit right? i.e Lipo is 8.4 and how about LiFE? 7.6?
- Should I go for 3.5 with LiFE or 4.5 with LiPO? from my experience Lipo may be damage with those high amp draw from 4.5 motor.
Thanks for your reply.

As for the ratings on the site that is the ratings for the specific pack not a single cell.

Yes the sequence is similar but the voltages are different. A 6.6 volt LiFe-Po peaks at 7.2 volts.
As far as what to run with each set-up as long as your geared with in the packs specs both will work.

says on ur site that this is a great pack for a b4. my TP and SMC units are 'shorter' than the listed dimensions on your pack and they just fit. 26mm vs 23.5mm. i dont see it fittin a b4, at least without tweakin somethin bad.

These packs are not designed to replace the performance of a Li-Po so no we are not pushing them for racing.
We have a B4 at the shop and the pack fits it just fine. It the same size as our 6500 Li-Po which also will fit in the B4 just fine.

Hello
I have been running 2x 2s2p a123 packs in a brushless truggy and I must say they have been working excellent. Ive been wanting to try 5s2p but they take up too much space(weight), now seeing these green packs I have to try the 16.5v 4500. How would the performance compare to a 4s lipo? Is it true that lipos have more punch?
I read a magazine test on these batteries that said they were more like nimh in performance but I find this hard to believe as the a123s ive been using are much better than nimh.
thanks

Thanks for the reply
Im already running tekins highest kv truggy motor the 2250(because of the lower 13.2 voltage I have been using). I think at 16.5v it will work great.
I would like to stick with this type of battery as I would rather not have the risk associated with lipo. I like your reference to dad and I agree, when my son is old enough for his first real rc he wont be using lipos(unless of course they are 100% safe by then).

Hello I need some guide on using the life packs on nitro 1/8th buggy. I've used 3 life packs and puffed them all my xray 808 buggy, they all puffed and went dead on me while I'm in qualifying and in the finals. I live in a tropichal country and we regularly run on a very hot days. I'm suspicious the packs went dead because of the heat especially the battery tray on my xray buggy is very close to the engine. Is this the real culprit and if it is what can I do to tackle the problem? I like the Life packs consistent voltage and I'm interested to buy your maxamps life pack but I'm very traumatic about the durability.
Btw, which of your life pack do you suggest for my xray nitro buggy?
