**** UPDATE ****
I took apart the N30 Battery and found that out of the 11 Nimh sub-c cells, there was only 1 bad cell. The bad cell was the last one in series connected to the negative side. If I by-pass that cell - I was able to fire up HID. I even tried by-passing 2 cells (using only 9 cells) and was still able to fire it up. I guess I could maybe just replace the single bad cell and I'll be back in business without spending too much $$$
**** UPDATE ****
My N30 batteries are dead - not enough juice to start the HID bulb - just flickers and dies. Tried the light with a 12 volt SLA and it turns on fine. So now I have to get replacement batteries. I can think of 2 options:
(1) Replace with 12 sub-C Nimh. (E.g Tenergy 5000mah sub-c)
Northern Lights rebuilt his with 12 nimh instead of the the original 11. http://www.candlepowerforums.com/vb...30-HID-rebuilt-5-Ah-72-watt-pack-and-upgrades
Pros:
Similar as existing setup - drop in replacement (just adding one extra battery) - using existing charger
Larger capacity: If I get the 5000mah sub-c, that would be 5000 X 14.4 = 72000 Wh
Cons:
Too much self discharge
Heavier ( approx 852 grams)
(2) Replace with 4 26650 IMR (e.g Batteryspace IMR 26650 4000mah)
Pros:
Lighter (approx 360 grams),
Low self discharge
Cons:
Less capacity - 14.8 X 4000 = 59200 Wh
Need a new charging system - smart charger to charge 4 IMR in series.
Would option 2 even work with the N30 HID ballast? Is the voltage too high?
Which would you guys choose? Do you guys have any other suggestions other than the 2 above?
