DFI LiPoly Custom Batteries
I saw a few posts about those wanting Lipoly batteries from other suppliers because they were cheaper or maybe faster to get. I found some directly from Thunder Power that were cheaper too but DID NOT have the added custom power drain protection circuit board. For the price that we pay for these batteries I would highly recommend using the custom batteries with this added feature to prevent overdraining battery cell damage. Thunder Power says that they have a new balancer to ensure that all cells are being charged properly. But, DFI said that it was not necessary for 3 cell packs. Someone else was asking what the additional leads were on the DF batteries from Thunder Power. That additional lead is for the optional balancer. [sm=thumbup.gif]
