Hello Harry,
Thank you for asking about our battery boxes. We would be honored to have you on our up-fitter list. We appreciate the help you provide on the forums. Please call Kim (54l-49O-4292) to get setup. You'll get discounted pricing. We also develop custom products for some of our larger clients.
The Lifeline GPL-31xt is 12.9 long vs the GPL-27T appears to be 12.1. Any chance of them fitting?
The inside of our
'fits-all-sprinter" battery boxes is 12.25" This is our most popular model as it fits all Sprinter NCV3 vans. But only on one side so just 2 batteries with this configuration. 220AH is plenty for most. We recommend using two FullRiver DC220-6 group 27 6V batteries in this box.
It is located underneath directly behind driver. This enables a short run of cables to the seat pedestal (for the DC-DC connection) and to the much used location for inverter and 12V panel inside behind the driver. (located on back of seat pedestal or on lower wall)
Related to this box, we produce solid panels for the lower wall openings behind the driver. Our sub-woofer panels (
first position,
2nd position) for these locations are quite popular and we run those same parts without holes for mounting electrical components. The 3/4" thick material we use is expanded PVC so will not rot or split. Holds screws extremely well which is great for mounting heavier electrical components. Non conductive too. Our panels fit into the wall so the front face is flush with the sheetmetal so they don't interfere with attaching wall panels. I'll run some today and post some photos to show how it they look.
We also produce battery boxes specifically designed to fit the
170WB 2500 and 3500. These are 10.625" wide so not designed for a group 27 but for a GC-2. This is due to space limitations. These and the 'fits-all-sprinter' version are deep enough for the largest (tallest) 250Ah CG2 batteries. GC2 batteries all share the same foot print but get taller as capacity increases.
The battery boxes for the 170 Sprinters locate just ahead of the rear wheels and can be mounted on either or both sides. So a total of 500Ah is possible and what we have in our Sprinter.
We feel it is vitally important to make every effort to maintain the stability of the vehicle as we add the weight of the build. That is why we place batteries between the axles and not behind them. And under the vehicle to help counter act the instability we get from placing weight up on the roof and high inside.
We really like the FullRiver batteries we get from NWBattery Supply in Portland, OR. Call and talk to Keith and tell him we sent you. You'll get a better price.
All the best,
Hein
