Frequently Asked Questions

Active balancing is a cell management technique that moves charge from higher-voltage cells to lower-voltage cells, keeping every cell in the pack at a similar state of charge instead of simply shedding excess energy as heat. So your battery won't get hot as soon as you start using it, like before.

At a continuous 3A rate, this balancing is strong enough to correct cell drift during normal use and to support higher, safer charge currents.

Practically, active balancing means you retain more usable capacity over the life of the battery pack, accept faster and fuller charging without hitting early cutoffs, and experience slower capacity fade so the system delivers steady performance year after year.

Without active balancing, individual cells drift to different States of Charge (SoC) over repeated cycles, which means the battery’s usable energy is effectively capped by the weakest cell; that mismatch forces earlier charge or discharge cutoffs, limits safe charge rates, reduces usable capacity, and accelerates overall ageing.

If the balancing switch is on, balancing will begin when the maximum cell voltage differential in the battery pack exceeds this value and will end when it falls below this value.

For example, if you set the balancing start voltage differential to 10mv and the balancing stop voltage differential to 5mV, balancing will begin when the cell voltage differential exceeds 10mV and end when it falls below 5mV.

The recommended balancing start voltage differential is 0.005V for cells over 50Ah, and 0.01V for cells under 50Ah.

When the lowest cell voltage is below the set value of 2000mV, active balancing will not begin, even if the cell voltage differential exceeds the set value. The balancing current represents the continuous current used to discharge the high-voltage battery and charge the low-voltage battery during energy transfer. The maximum balancing current represents the maximum current during energy transfer, which does not exceed 3A.

The difference between 1A, 2A, and 3A active balance lies in the maximum current (amperage) they can use to transfer energy between battery cells.

In essence, a higher amperage rating means the active balancer can correct imbalances more quickly and handle larger cell capacities more effectively. All types use non-dissipative energy transfer methods, meaning they are more efficient and generate less heat compared to passive balancing systems.

1. Cell Overcharge Protection and Recovery
When the voltage of any cell is higher than the set value of the cell overcharge voltage, and the time of duration reaches the cell overcharge delay, the system enters the overcharge protection state, the charging MOS will turn off, and the battery cannot be charged.After the cell overcharge protection, when the voltage of all cells drops below the cell overcharge recovery value, the overcharge protection state is released. It can also be released by discharge.

2. Overall Overcharge Protection and Recovery
When the overall voltage is higher than the overall over-voltage set value, and the time of duration reaches the overall overcharge delay, the system enters the overcharge protection state, turns off the charging MOS, and cannot charge the battery.When the overall voltage drops below the recovery value of the overall over-voltage protection, the overcharge protection state is released, and it can also be released by discharge.

This 48V 314Ah LiFePO4 solar battery performs excellently with active balance and Bluetooth features. Customers said it "works perfectly" with "massive construction" quality. Fast delivery praised. One concern: the battery's heavy weight may require depot pickup rather than home delivery in some cases.

Working fine, minimizing Grid import.

I have used this battery for 2 weeks with a VEVOR Hybrid Solar Inverter, 6000W (EM6200-48L) and 3,6 kW solar panel. The communication with inverter and the optimal parameter setting/testing took a week. Finally the AGM mode via RS485 - VOLTRONIC and max. charging current=50A provide the expected operation. On sunny days the battery exceeds 100% SOC and provide enough energy until midnight by 1 kW average Load. On timely changing cloudy days (PV input 300-3000 kW) the battery discharge real-time provide the missing Load energy, so the Grid usage=0.

Integrazione consigliatissima ed economica

Ho acquistato la batteria solare a rack 48v e l'ho collegata alla power station Ecoflow delta 3 da 1 KW con il cavo arrivato in omaggio da wattcyle, ringrazio infinitamente Wattcycle, il tutto inserito nel mio camper come da foto. Soluzione eccezionale, ora ho una autonomia eccezionale ed un funzionamento veramente integrato ad un prezzo complessivo molto basso, La power Station Ecoflow riceve la carica da un pannello solare sopra il camper, 370W a pieno sole, che cosi carica il tutto.. L'installazione è stata valutata con attenzione per inserirla e fissarla in sicurezza, ammortizzata senza urti nel camper.

Sehr gute Batterie

Perfekte Qualit?t und hohe Kapazit?t (5120 Wh, die tats?chlich komplett nutzbar sind).

Ausgezeichnete Batterie, seri?ses Unternehmen

Ich teste die Batterie seit etwa einer Woche und kann bereits sagen, dass ich sehr zufrieden bin. Sie arbeitet absolut ger?uschlos und wurde in einer sehr stabilen, gut gepolsterten Verpackung geliefert.

Die Batterie verh?lt sich genau nach Handbuch �C selbst bei hoher Last (1,5/2 kW Spitze) zeigt sie keine unerwarteten Spannungseinbr��che (wie es sich f��r eine gute LiFePO4-Batterie geh?rt).

Die 5 kWh Kapazit?t wirken absolut realistisch. Jetzt, wo die W?rmepumpe nachts kaum l?uft, komme ich problemlos bis zum Morgen.

Zuvor hatte ich 16 AGM-Batterien... das ist ��berhaupt kein Vergleich.
Ausgezeichnetes Produkt, sehr zu empfehlen!

L?ste unser Problem mit Lastspitzenentgelten

Meine Solar-Firma hat f��r einen Gewerbekunden 8 Einheiten installiert. Die 100% Entladetiefe und die Lebensdauer von 6000 Zyklen haben die Konkurrenz deklassiert. Die Lastspitzenentgelte des Kunden sind um 65 % gesunken! Die Installation war werkzeugfrei �C die Module passten einfach in Standard-Racks. Der Kundendienst hat sogar remote dabei geholfen, die BMS-Einstellungen anzupassen. Absolut empfehlenswert f��r gewerbliche Anwendungen.

Bisher durchaus zufrieden

Der Akku hat alles, was unbedingt n?tig ist, und das in guter Qualit?t. Der Speicher arbeitet sehr gut. Diesen Akku werde ich auf jeden Fall bei der Planung meiner Solaranlage ber��cksichtigen.
