+  * Product page: [[https://www.pytesess.com/High-Voltage-Battery/HV48100.html|HV48100]]
-  * Current HV line: HV Series (HV48100, HV48300, HV48100 SE); 51.2 V / 5.12 kWh BMU modules in series under HV48100 BCU controller, working range 200 - 870 V
+  * Datasheet: not publicly linked; see the [[https://www.pytesess.com/Catalogue/|Pytes download centre]]
+This page covers HV48100 and HV48300 Max.
+Pytes also offers HV48100 SE and HV48300 Max SE. The calculations below do not apply to the SE models.
+===== Use with the HS19 (650 - 1000 V DC) =====
+These calculations check voltage limits only. They do not establish compatibility.
+They keep the full stated battery voltage range within the HS19 and battery controller limits.
+**HV48100**
+  * Modules per stack: **14 or 15** are within the product range.
+  * Voltage range: **665 - 870 V DC**
+  * Nominal Capacity per stack: **71.68 - 76.8 kWh**.
+**HV48300 Max**
+  * Modules per stack: **15 - 17**.
+  * Voltage range across these configurations: **672 - 979.2 V DC**.
+  * Capacity per stack: **241.14 - 273.29 kWh**.
+  * A stack with 14 modules can fall to 627.2 V. A stack with 18 modules can reach 1036.8 V.
+Each stack has its own voltage range. The combined range above is not the range of each stack.
