2.9 Lithium-ion (LiFePO₄) batteries
Li-ion batteries do not suffer from sulfation.
But Li-ion batteries are very sensitive to under voltage or over voltage².
Li-ion batteries therefore often have integrated cell balancing and under
voltage protection (UVP) circuitry.
Some reverse polarity protected chargers will not recognize a battery
when the UVP has tripped.
The Blue Smart Charger will however automatically reset the UVP and
start charging.
Important note:
NEVER attempt to charge a Li-ion battery when its temperature is
below 0°C (32°F).
2.10 Low current mode
Some lead acid batteries can overheat if charged with a current
exceeding 0.3C (C is the capacity in Ah. A 12Ah battery for example
should not be charged with a current exceeding 0.3 x 12 = 4A). The low
current mode (charge current limited to 4A or less, see technical
specifications) should therefore be used to charge low capacity lead-acid
batteries.
