Which cells to buy!!

[Oscar]

In summary, what I've heard/experienced:

Batt 4000 - Junk stay away

IB4200- Superfast, but unreliable

Gp4300- Fast and reliable, but performance begins to drop off after a few charges

Gp3700- Fairly fast, super reliable, but very hard to find for sale.

Ep4200- (Firecracker) Not many around, but supposedly fast and reliable.

gp 3700's are easy to find for sale. e.g ebay, storm racing, i can get you some if you so wish...... .
























for a fee

Hey guys,

I been using 4 saddle packs of Non matched IB4200SHV's for the last 8 month's, they are still as good as the day I purchased them but this is mainly due to good maintenance.

I have had to bring back some cells from the dead but since using this procedure I have not had any trouble. First I discharge my cells individally using my CDC v6.0 after a meeting, then allow to equalise and cool for about 20 minutes, then I put 30% charge in the pack for 2 weeks storage until next meeting. The night before a meeting I discharge each cell again and charge pack with 4000mah's of charge (This keeps heat to a minimum and stops pack from venting). I then boost the pack on race day an hour before im ready to use (takes about 7-8 minutes to fully charge). Boost function basically discharges the pack for 40 seconds at 6 amps (personal setting) this is the same amp setting as the charge rate, as this gives me a rough idea of how many mah im getting into a charged pack. (My personal settings are) charge at 6 amps, Boost discharge/charge at 6amps and single cell discharge at 20 amps.

I remember the good old days with the 1400SCR's they were a great pack, though I have been looking at trying a Nicad Sanyo 2400SCR pack as they will easierly last the distance with my 4.5 novak, they need less maintence and are lighter than the 4200 nimh.

Does anyone have any experience with the sanyo nicad 2400SCR?
