Compare the types of batteries used with electric bikes, advantages/disadvantages of each. SLA (sealed lead acid) NiCd NiMh Lithium Polymer LiPo Lithium LiFePo4 Weight Heavy 25% lighter than SLA 40% lighter than SLA 70% lighter than SLA 70% lighter& 50% smaller than SLA Charge Cycles; 150 - 300 500+, long recharge time 500+, long recharge time 800+, long recharge time 2000+, Rapid recharge time Amperage Output High - 40+ amps High - 30+ amps Limited - 15 amps Average - 10, 15, 20 amps Average - 10, 15, 20 amps Charging Issues Sensitive Tough - new NiCd Very Tough- can be left in Very tough - can be left in Very tough - can be left in must be charged immediately don't have memory problems discharged state for long discharge state for very discharge state for very after use periods of time. long periods of time long periods of time SLA vs LITHIUM You can get more range out of the lithium pack with the same aH rating as a SLA, because the you can get the full rated energy out of LITHIUM at high discharge rates. Also, since the voltage declines only a little as a lithium pack is discharges, you are also getting more actual watt-hours (volts*amps*time) of energy for the same "amp-hour" rating. The weight savings is very noticeable. The standard ratings for lead acid batteries are exaggerated for the discharge rates we are interested in. Most good SLA battery manufacturers provide data sheets with the energy and run-time you can actually expect to get out of them for a given power (amperage) output. |
| IMPORTANT!!! SLA Batteries do not like being left in a discharged state.Irreparable damage will occur if they are not charged immediately after use. "Re-Charge Your e-Bike Right Away" to get lasting performance. 300 CYCLES & MORE. |
| SLA BATTERIES - Will last longer if you charge them slowly (1 amp). Do not use chargers above 3 amps. - Do not use automotive or motorcycle battery charger to charge SLA batteries - Automatic SLA battery chargers are designed so that they can and will not charge defective |

| BRUSH TYPE KITs; ARE POWERFUL , HOWEVER, THEY DRAIN THE BATTERIES FASTER. IF YOU WANT MORE DISTANCE FROM THIS TYPE OF KIT, DO NOT HOLD THE THROTTLE AT FULL POWER. IT IS POSSIBLE FOR A 200LB PERSON TO GO 10-15 MILES (EVEN WITH HILLS) PRIOR TO NEEDING A CHARGE IF PEDAL ASSIST IS USED CONSTANTLY, BUT THE BATTERIES WILL BE VERY DEPLETED. 12ah; 10-15 miles (mixed terrain) is more realistic for BRUSH type CONVERSION KIT. 12ah; 12-18 miles (mixed terrain) is more realistic for BRUSH-LESS CONVERSION KIT. |
| We are selling more LiFePo4 batteries because they are lighter, longer lasting, much more powerful & require less attention compared to SLA Batteries. Try before you buy! Unless you Special Order a LiFePo4 Battery, Our KITs Come With Three Extended Range12Volt (12ah or 14ah) Batteries SLA (Sealed Lead Acid), Wired in Series (36volts) - ITS PRETTY EASY SLA BATTERIES TO GO 20 MILES WHEN ALL CONDITIONS ARE PERFECT, i.e; NO HILLS, GREAT BIKE/TIRE PERFORMANCE, WIND DIRECTION, RIDERS WEIGHT & PEDAL ASSIST. DRAINED BATTERIES ARE INDICATED BY A FLASHING YELLOW LIGHT ON THE THROTTLE (less than 20% power left). RIDING WITH A YELLOW THROTTLE LIGHT ON WILL SHORTEN THE LIFE OF THE BATTERIES. (because they are 80+% drained) TIP FOR GETTING MORE DISTANCE; IF YOU COULD MAINTAIN A STEADY 3/4 POWER ON THE THROTTLE WHILE PEDALING...YOUR DISTANCE IS INCREASED GREATLY 15-20 MILES. COMPARED TO BRUSH TYPE MOTORS...THE BRUSH-LESS MOTOR IS APPROX 25% MORE EFFICIENT WHICH TRANSLATES TO MORE MILES TRAVELED BEFORE THE LOW BATTERY LIGHT COMES ON. Slow down; 1 Mph decrease in speed could extend your range 1 Mile! WAYS TO DRAIN THE BATTERIES EXPONENTIALLY & OVER STRESS YOUR MOTOR 1) GO UP A HILL AT FULL THROTTLE & NO PEDALING. 2) TAKE OFF FROM DEAD STOP W/OUT PEDALING. Tips to Extend Battery Life 1) Even when your scooter is not being used batteries like to be charged at least once a week for about 6 to 8 hours. 2) If you are using your scooter daily plug it in daily. 3) Batteries last much longer when they are not fully discharged. 4) Batteries like to be plugged in as soon as possible after use, this also extends battery life. 5) Batteries don't like to be left on a charger for weeks or months, 6 to 8 hours up to a couple days is good enough. Hope this helps keep your batteries healthy and long lasting. Have a safe ride. Thanks for your business. |
| REGENERATIVE BRAKING OR PEDAL-CHARGING CAPABILITIES! Regenerative braking, is about 7-10% efficient &, you'd have to pedal 5 times as hard to generate power as you would to just pedal the vehicle directly. Regenerative braking adds cost and complexity to the system, while reducing reliability. A Bike doesn't have sufficient weight to use the braking system for re-gen. Some Re-Gen Controllers may state there is no resistance to generate electricity back into the batteries...Don't Believe It! |
