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 JK Smart BMS 8S-17S 80A can carry at its rated 80 A:
| Series | Nominal | Full charge | Cut-off | Power at 80 A | Typical use |
|---|---|---|---|---|---|
| 8S | 25.6 V | 29.2 V | 20.0 V | 2.0 kW | 24 V inverters, 3.6-4.2 kW hybrid inverters, solar storage |
| 15S | 48.0 V | 54.8 V | 37.5 V | 3.8 kW | 48 V inverters, e-rickshaws, e-loaders and solar storage |
| 16S | 51.2 V | 58.4 V | 40.0 V | 4.1 kW | 48 V inverters, e-rickshaws, e-loaders and solar storage |
| 17S | 54.4 V | 62.0 V | 42.5 V | 4.4 kW | - |
Inverter, cable and fuse
On a 16S pack (51.2 V) the BMS passes up to about 4.1 kW, so it suits an inverter or motor controller drawing no more than about 4.1 kW from the battery (about 3.7 kW of AC output at 90% inverter efficiency). For the main battery leads use at least 16 mm² (6 AWG) copper cable and a 100 A DC fuse or breaker; if your load pulls more than 80 A for long, choose a higher-current BMS.
16S पैक (51.2 V) पर यह BMS लगभग 4.1 kW तक की पावर दे सकता है। मेन बैटरी केबल कम से कम 16 mm² (6 AWG) कॉपर रखें और 100 A का DC फ़्यूज़ लगाएँ।
Closest alternative: the JK Smart BMS 8S-24S 80A differs only in lifepo4 pack voltage 25.6 V (8S) to 54.4 V (17S) here against 25.6 V (8S) to 76.8 V (24S); series (cell count) 8S to 17S here against 8S to 24S, and this one costs ₹410 less than it.
