SIZING & FIT GUIDE
साइज़ और फ़िट गाइड
Which packs this BMS fits
Pack voltages for LiFePO4 cells (3.2 V nominal, 3.65 V full, 2.5 V cut-off per cell) and the continuous power the Daly LiFePO4 BMS 4S 100A can carry at its rated 100 A:
| Series | Nominal | Full charge | Cut-off | Power at 100 A | Typical use |
|---|---|---|---|---|---|
| 4S | 12.8 V | 14.6 V | 10.0 V | 1.3 kW | 12 V systems, small UPS and solar lights |
Inverter, cable and fuse
On a 4S pack (12.8 V) the BMS passes up to about 1.3 kW, so it suits an inverter or motor controller drawing no more than about 1.3 kW from the battery (about 1.2 kW of AC output at 90% inverter efficiency). For the main battery leads use at least 16 mm² (6 AWG) copper cable and a 125 A DC fuse or breaker; if your load pulls more than 100 A for long, choose a higher-current BMS.
4S पैक (12.8 V) पर यह BMS लगभग 1.3 kW तक की पावर दे सकता है। मेन बैटरी केबल कम से कम 16 mm² (6 AWG) कॉपर रखें और 125 A का DC फ़्यूज़ लगाएँ।
Same rating from another maker: the JBD LiFePO4 BMS 4S 100A (JBD) matches this Daly charger on paper, and this one costs ₹720 more than it. Both suit the same batteries; pick by price or the brand you already use.
Closest alternative: the Daly LiFePO4 BMS 4S 150A differs only in continuous discharge current 100 A here against 150 A, and this one costs ₹2,110 less than it.
Closest alternative: the Daly Smart LiFePO4 BMS 4S 100A differs only in communication - here against UART, CAN / RS485; type Standard BMS (protection board) here against Smart BMS, and this one costs ₹1,750 less than it.
