SIZING & FIT GUIDE
साइज़ और फ़िट गाइड
Which packs this BMS fits
Pack voltages for Li-ion (NMC) cells (3.7 V nominal, 4.20 V full, 3.0 V cut-off per cell) and the continuous power the JBD Li-ion (NMC) BMS 20S 100A can carry at its rated 100 A:
| Series | Nominal | Full charge | Cut-off | Power at 100 A | Typical use |
|---|---|---|---|---|---|
| 20S | 74.0 V | 84.0 V | 60.0 V | 7.4 kW | 72 V e-scooties, e-bikes and golf carts |
Inverter, cable and fuse
On a 20S pack (74.0 V) the BMS passes up to about 7.4 kW, so it suits an inverter or motor controller drawing no more than about 7.4 kW from the battery (about 6.7 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.
20S पैक (74.0 V) पर यह BMS लगभग 7.4 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।
Closest alternative: the JBD LiFePO4 BMS 20S 100A differs only in cell chemistry Li-ion (NMC) (3.7 V cells) here against LiFePO4 (3.2 V cells); nominal pack voltage 74.0 V here against 64.0 V, and this one costs ₹280 more than it.
