[RE-wrenches] Hawker versusu MK

[frenergy]

Here's a third for 2V Surrette's....... However you should discuss details 
with this list or someone at Surrette regarding your application.  For an 
example, Solar Power source? C/rate? Are you replacing a set of golf cart 
batts or batteries with similar charging needs as these large cells?  The 2V 
1766AH cells seem to prefer being charged longer and slower than say a T-105 
or an L-16 to ensure proper SG's (others please chime in hear with 
similar/different experiences).

        Yes, being easier to move is great...a handtruck or 2 bodies works 
perfect.  Dual container simplifies your battery box AND keeping the tops 
clean. The large/tall area above the plates means less watering.

        One warning though is insist on getting all the cells from one 
batch.  If your supplier has to wait for cells from some other distributor 
to make up your pack, ask to wait for all cells to come from one production 
batch.

        I know a lot of folks have and love metal cased 12V "packs" (I'm 
still working one myself) but I won't be going that route again for a 
variety of reasons.  It's a big investment, do your homework.

there's 2 more cents worth.
