Test Results for Powerizer 4200 mAh stick pack
Anonymous (Anonymous) 7/18/2014 11:57 AM
I went out to Racers Haven to practice oval racing. *Losi XXX T- Novak Cyclone, Birdman P2K2 pro stock motor, Spektrum DX3 radio w/ Z590 Hi-Torque Race Servo and SR3000 Receiver Run Time: A- For being on full throttle 75% of the time, running for 10-12 minutes is a long time. The battery just kept putting out the juice and my truck kept going. In comparison to other drivers, I was on the track a little longer the everyone else so that was nice. Top Speed: B On the oval the top speed was decent, but not going to pass other trucks with authority. Unfortunately, there was only modified trucks at the track so it was hard to see just how fast these batteries are. I would guess you can easily race with these packs at a club race and compete. Acceleration (Punch): B Coming out of the corners there was ok acceleration. This was a stock motor so I wasn’t expecting much. Overall Performance: B+ For how long I could drive, and the good top end, I thought these are a decent pack for club racing Oval stock. I was turning 8 -9 second laps on a dirt oval about 70-80 yards round so I will have to go back and see what the guys do in the races. From this perspective though, Powerizer has a quality battery that anyone can afford. Pros: - Cant beat the price- $35.00 for a club racing pack. AMAZING!!! -Long run time. -Perfect local club racing pack, oval of off-road. -The quality of the soldering is perfect. -The clear plastic wrap really makes the batteries look sharp Cons: -Would appeal to hard core racers if they also had a pre soldered side by side pack with battery bars instead of deans plugs.

Great Batteries

At first I didn't really notice anything different from my other packs witch were 3000mAh, but about 6 minutes later when my other packs would be slowing down these babys kept on going ! They lasted about 10-12 mintes of just normal use in the grass and around the dirveway. I also notticed that it didn't bog down as much when running in the grass and up the hill that I live on. They seemed to provide a great amount of power and reliability that I needed when trying to get over obsticals and curbs.

largest selection of batteries I've found
WingRider05 (Pinson, AL) 6/29/2012 3:44 PM
BatterySpace has one of the largest selection of batteries I've found. Not only are batteries carried, but a large selection of chargers, wiring, connectors and peripherals. My order was filled and shipped in a very timely manner. My only complaint was the shipping. Not the fault of BatterySpace, it took UPS 12 days to ship one small package! I've ordered items from France and it only took 8 days. My package arrived well packed with an invoice. All parts were wrapped in plastic for protection. A set of instructions were included on the proper care and charging of the batteries. Great place to shop, a good thumbs up. The shipping was slow, not the fault of BatterySpace.
