I wouldn't recommend splitting the packs after they've been one, if the pack voltage varies more than 0.1v it can cause the packs to try and balance themselves out and the too-ing and Fro-ing of current has been known to cause burning packs (Scorpion at Aylsebury is a good example).
If you can get a good PSU for cheap then do, I pretty much always charge my batteries at their C rating or close because my FW takes a lot of power out of them and I have to charge them for the next fight. 4 hours is a long time between FW fights, especially when its a 2 hour show with 2 FW fights at least .
So I can charge them with a lower current but It will take forever. Hmmm, I'll have to think about this one.
EDIT: 3.7 Ah at a maximum of 25 A would give around 9 minutes of battle. Sounds OK, that'll last three fights at least.
