- Specifications are published for it, each with its source.
- 4 figures are contradicted by another credible source. Both readings are shown below, and neither is presented as the correct one.

“not series capable but can be connected in parallel up to sixteen times. Make sure that the total amount of these batteries in your config- uration never exceeds sixteen total batteries. When connect- ing batteries in parallel, ensure all batteries are within 1 volt of one another.”

It should not be used with BDGR batteries." NOT joined to bigbattery-48v-eagle-2-32ah: this FAQ names bare "EAGLE", not "EAGLE 2" -- and the sibling 20A charger's own FAQ shows BigBattery use both terms deliberately as two different items in one sentence.
Compatible carts
Sources do not establish: Which Club Car model. BigBattery name Club Car as a brand their pack works with and name no specific model, year, trim or controller rating in that statement — so this is not a claim about this model in particular. Also not established: this cart's system voltage against the pack's, the battery compartment it would need to fit, the continuous and peak discharge its controller demands against what this pack's BMS delivers, and whether this model's charger is safe for this chemistry — none of it is addressed by a brand-list statement. The same applies to E-Z-GO, ICON Electric Vehicles and Yamaha Golf Car.
