2.9 Lithium-ion (LiFePO
₄
) 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.
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.
