Aku laadimine

[renx]

Ei juhtu selle LiFePo4 akuga ka tobulaadijaga laadides midagi.Mul neljandat hooaega Vtx-l peal ja toimib siiani ja pole see tsikkli laaddimissüsteem mingi nutikas.Äi pole ka 1,5c juures käivitamis raskusi olnud.Ka kuu ajase seismise peale pole laetus vähenenud.Eks näis,kaua kestab.

Reaalsuses tuleks välja vahetada ka pingeregulaator, kui vahetada aku liitiumi vastu. Üldiselt on akudel oma control unit(BMS) sees mis tegeleb selle majandamisega laadimise ajal. Kui seda pole siis saab vabalt aku läbi lasta.
Liitium tahab 14+ volti saada. Tavaline aku ~13v.

Healthy motorcycle charging system p**s out about 14 volts at 2,000 rpm, and a lithium battery needs between 13 and 14 volts to charge. If your bike produces less than that because of a tired charging system, the lithium battery will not charge, and it will ultimately run out of juice, leaving you high and dry. (This charging system issue is a contributor to the myth about lithium batteries not lasting as long as lead-acid batteries.)
Since many battery chargers – including the smart ones – are designed for the 12.8-volt requirements of lead-acid batteries, they will not charge most lithium batteries.Additionally, smart chargers expect to be connected to six 2 volt cells, but lithium batteries typically have four 3.3 volt cells. So, they’re not really speaking the same electrical language. Batteries with special circuitry can work with this lower voltage. However, it won’t be an optimum set up. Consequently, it is a good idea to get a smart charger designed for lithium batteries.

A 12v lithium LiFePO4 battery fully charged to 100% will hold voltage around 13.3-13.4v. Its lead acid equivalent will be approximately 12.6-12.7v. A lithium battery at 20% capacity will hold voltage around 13V, its lead acid cousin will be approximately 11.8v at the same capacity. As you can see, there is very narrow window of voltage with lithium, less than 0.5V over 80% capacity.
