Dual Battery system
Overall view of my 1st caliber
24.08.2002 Add a dual battery system for more safety. I have no heli with only one battery. Here is why:
| Problems | 1 battery pack | 2 packs + mechanic Switches | 2 packs + Electronic switch |
| Additional cost of system | reference | + 55⬠| + 180⬠|
| Open circuit between battery and switch’s pack | Failure | Redundant | Redundant |
| Open circuit in one of the pack | Failure | Redundant | Redundant |
| Battery short circuit in one pack | Failure | Failure | Redundant |
| One pack not fully charged | Failure | Redundant | Redundant |
| Switch failure (assumes between RX and backup sys) | Failure | Redundant | Failure |
| Battery connector from backup system to the receiver | Failure | Redundant | Failure |
Build yourself a dual switch
