Tried the battery tester this evening. Looks like all the batts check out except possibly one dud. Maybe should have saved our money and made our own tester too. It's just a big resistor / volt meter.

Weighty matters...

Looking at batteries, we can probably - barely - get 4 under the hood (plus the 12v battery). This'll have the front overweight though, compared to OEM...

We took out approx:

- 150 lbs, wet engine
- 10 lbs, alternator
- 20 lbs, cooling system
- 15 lbs, cat/front exhaust
------
= 195 lbs, total removed (front)

Added approximately:

+ 110 lbs, motor
+ 10 lbs, adapter/coupler
+ 252 lbs, 4 floodies @ 63 lbs each
+ 45 lbs, batt cables, controller, contactors, pot box
--------
= 417 lbs, total added (front)

= 222 lbs overweight in the front. Kind of like having a big dude sitting on the hood, it'll probably have the car squatting an inch or 2 down on the suspension.

We'll be putting 252 lbs in the back (4 batts). But there's still more stuff to take out (gas tank, rest of the exhaust). Ballpark, we're probably adding about 350 lbs to the car with a 48v setup. 36v would be like adding about 214 lbs.

The car's Max Load rating (passengers + stuff) is 695 lbs.
