Charging Technology
Charger termination voltage is a function of series count. It is not a preference.
Multiply the series count by 3.65 V and you have the charger. Sixteen cells terminate at 58.4 V, nineteen at 69.4 V, twenty-three at 84 V. Every JRP charger exists because a JRP architecture needs it.
Architecture and charger
| Charger | Architecture | Compatible packs | Typical charge time |
|---|---|---|---|
| 58.4V / 6A | 48V Series | 48V / 30A | ~5-6 h |
| 58.4V / 10A | 48V Series | 48V / 45A, 48V / 60A | ~5-7 h |
| 69.4V / 6A | 60V Series | 60V / 24A, 60V / 30A | ~4-6 h |
| 69.4V / 10A | 60V Series | 60V / 45A | ~5 h |
| 84V / 6A | 72V Series | 72V / 30A | ~5-6 h |
| 84V / 10A | 72V Series | 72V / 45A | ~5 h |
The failure mode this prevents
A 69.4 V charger on a 48V pack pushes each of sixteen cells to about 4.3 V — far past the 3.65 V limit for LFP. The BMS will try to stop it, but a protection system is a last line of defence, not a substitute for using the right charger.
