New Ult Slash with the 8.4 4200mah series 4 batteries.
On the battery it states to charge at 3a for life and 4a for performance. So far so good. Using the C formulas that are bouncing around I've been charging at 4.2a and everything seems ok though the batteries do get warm. About 100degf (guessing). Truck runs strong but I have nothing to compare it too due to the weather, brrrr.
Should I "cycle" the batteries and how often?
Can I charge at a higher amp rating for more kick, say 5 amps?
What should the fresh charged voltage be? The charger says 1-2C for fast charge.
Can I safely charge a partially discharged battery safely?
Thanks and Happy New Year. Cliff
