Alternativakku mit NMC Einzelzellen

Hi Guys,

I already drove about 100kms, now I'm about 3.4v that is about 30% of battery, and I thing is about 50kms.

I define the limits of the Battery to 4.05v and 3.05v; This is the table until now.

4.05 ~100% 0 km 145 km
3.90 ~85% 20 km 125 km
3.83 ~75% 27 km 118 km
3.75 ~68% 38 km 107 km
3.70 ~60% 46 km 99 km
3.68 ~57% 52 km 93 km
3.60 ~50% 62 km 83 km
3.55 ~45% 72 km 73 km
3.50 ~40% 82 km 63 km
3.45 ~35% 90 km 55 km
3.43 ~33% 97 km 48 km
3.40 ~30% 102 km 43 km
3.35 ~25% 110 km 35 km
3.30 ~20% 120 km 25 km
3.25 ~15% 130 km 15 km
3.20 ~10% 138 km 7–10 km
3.10 ~5% 145 km 3–5 km
3.05 ~0% 150 km 0

Don't forget is a Twizy 45 with 218ah Leah Modules;

Solved; Thanks Guys, just change de difference of voltage.

Does the "Metric 0.000V -3.3xxV" mean, there is a cell at 0.000V? Or is it including the unused cell connections 15-16 in the metric? What are the individual cell voltages?

below 3.30V (no-load Cell Voltage) there is only 7Ah left in the cells (3%). The Management should map 5% SOC to 0% User-Displayed-SOC and block discharging at that point, so the cells are not damaged when not instantly recharged, like with your charging problem.

Hallo, ich habe am Freitag auch meine Akkus aus China gekommen.

Alle Zellen hatten 3,90V, Isolatorplatten und Verbinder war vollatändig dabei.

Die Letzten Kilometer kamen der DPD - sehr kurzzeitig angekündigt.

Gekauft am 15.1.2026 für 854 USD / 742 €
Geliefert am 20.3.2026

Natürlich ist das nur ein Anhaltspunkt, da sich momentan viel verändert hat.

Jetzt BMS und Busbar kaufen / warten.
Trotzdem im Voraus danke ,für alle im Forum die hier die Tipps geben.
