 Solar is typically a moderate (or "soft") charging source so the guidelines above are probably close enough to start from.  Alternator charging from [[electrical:12v:directcharginglfp|combiner]] or large [[electrical:12v:b2b|DC-DC]] may be high ("firm") enough for SoC estimates to be artificially high.   Solar is typically a moderate (or "soft") charging source so the guidelines above are probably close enough to start from.  Alternator charging from [[electrical:12v:directcharginglfp|combiner]] or large [[electrical:12v:b2b|DC-DC]] may be high ("firm") enough for SoC estimates to be artificially high.  
  
-So while we can say with confidence that a 100Ah Li battery charged at 20A to 14.0v will be ~100% SoC, the same battery charged to 14.0v at 80A might only be at 75% SoC.  The amp counter will probably help here during charging although even it can be thrown off. +So while we can say with confidence that a 100Ah Li battery charged at 20A to 14.0v will be ~100% SoC, the same battery charged to 14.0v at 80A might only be at 75% SoC.  And it **could get damagingly overcharged** if charged to 14.0v very gently at something like 5A.((the BMS cannot detect this scenario))
