Prevent Batteries from Puffing?

[Capt. Crash]

Mine didn't like 25C batts from Max Amps...but things were good when I went to 30C.

i also use the turnigy 5000mah 2s 20-30c lipos and havent
had any problems there are four things that can cause a PUFF
over charging
over discharging
not enough c rating (the batteries dont have enough amps to supply the system with what its asking for)
low quality cells ( a low quality cell might be able to supply the advertised c rating and mah but might not be able to hold it as long as a high quality cell)

mathmaticly the 5000mah 20c should be able to withstand a 100amp draw max but like was commented above buy the highest c rating you can afford and you cant go wrong plus you can always use them in other boats

Mine are 30C 5000mah batteries. both have puffed now. Seems like they are not very good if people are using 20C-30C regularly. Have some Turnigy 40C coming.
