Compatible carts
These figures match. Nothing states that the packs are interchangeable — that is our observation of published specifications, not a claim by the manufacturer or a test by us. Even when every stated figure agrees, these can still differ:
- BMS communication — many packs authenticate with the cart over a data bus
- Maximum discharge current, which the capacity figure does not express
- Pin assignment inside an identical connector shell
- Mounting rail, lock and cradle — a shared case is a shared shape, not a fit
- Firmware or serial pairing, where the manufacturer uses it
Worth confirming with the manufacturer or a dealer before buying.
Only a battery of BCI group GC-2, which is how Yamaha's manual lists this cart's battery and how Trojan state the T-105's group size — check yours before buying. — applies to Yamaha Golf Car G14E Ultima, Yamaha Golf Car G16E Ultima
Sources do not establish: Battery compartment dimensions, any BMS/charger pairing beyond what the maker lists, and model years.
Applies to some of the listed carts, across Star EV
Sources do not establish: The manual's battery table gives a group size and a reserve capacity. It gives no voltage and no count, so how many batteries this cart carries, and whether a 6-volt battery is the voltage it needs, is not established here. Also not established: that either company considers the two a fit — the comparison is between two stated group sizes.
Applies to Yamaha Golf Car G14E Ultima, Yamaha Golf Car G16E Ultima

Yamaha Golf Car
Only Yamaha Adventurer Two (electric, JW3/YT2E), 2017-2018 manual edition (LIT-19626-81-18), per the manual's own SPECIFICATIONS - BATTERIES table. Corroborated exactly by LIT-19626-81-13 (2015 edition, same table, "YTF2E UTILITY VEHICLE" column, identical battery and RC figure). Check yours before buying.
Only the Drive² Concierge 6 PowerTech AC, and Yamaha's own sources disagree on its standard pack: one tab of Yamaha's archived specification page (captured 17 February 2025) says eight 6-volt Trojan T-105, while another tab of that page and the 2019 owner's manual (LIT-19626-A0-21) say six 8-volt Trojan T-875. We have not settled which is standard — check yours before buying.
Only 8 of these, which is an option Yamaha offer in place of the standard pack on Yamaha's own specification table for this model — check yours before buying.
Only Yamaha UMAX 2 Rally AC, 2025 manual edition (LIT-19626-A4-03), per the manual's own SPECIFICATIONS - BATTERIES table. Corroborated by LIT-19626-A2-52 (2023, identical) and LIT-19626-A0-18 (2019, heading its own YUM2E column "UMAX SPORTS" — Yamaha's own manual index files this same 2019 document under a "Rally" label, "UMAX TWO RALLY (48V - POWERTECH AC MOTOR - LONGBED)"), all three stating the identical battery and RC figure. Check yours before buying.
Only Yamaha state this for the 2027 UMAX AC and give no other option for it. They do not say which earlier model years take the same bank. Check yours before buying.
Only Yamaha UMAX Rally 2+2 AC, per the page's own SPECIFICATIONS table (ENGINE/DRIVETRAIN, AC tab). Check yours before buying.
Only 8 of these in series, which is how Yamaha's manual lists this cart's battery: "US Battery 6V Deep cycle GC-2 8 pcs./Series" — check yours before buying.
