Frequently Asked Questions
Will installing this kit void my warranty?
Yes, installing this kit would (we suggest) void the warranty on your SurRon Light Bee Battery, if it is still under a warranty period.
What is the difference between the Stage 1 and Stage 2 Upgrade Kits?
The key difference between the Stage 1 and Stage 2 Power Upgrades is which battery you are using or going to use in your Light Bee. The Stage 1 Upgrade is designed to work with a BMS bypassed 60v SurRon Battery, and can work with either a BAC4000 or a BAC8000. The Stage 2 Upgrade is designed to work with either a 72v Battery or increased Ah 60v Battery.
What Kit should I get the BAC4000 or the BAC8000?
The BAC4000 is perfect for the 60v SurRon BMS Bypass upgrade. The BAC8000 Upgrade is specifically designed for people who plan to invest in a larger Battery, down the track, perhaps after your 60v battery sags. This means - that you do not have to upgrade your ASI controller again.
Can I install this kit myself?
You can purchase the kit without fitting and installation.
Will doing a bypass decrease the life of my battery?
Yes, this may decrease the life of your battery. It depends on a lot of factors exactly how much this will decrease the life of your battery, e.g. age and health of the battery before the bypass, correct maintenance and care for the battery after the bypass, etc.
How much power can I expect to get from this upgrade?
The Stage 1 tune is between 7.5kW and 8kW. This is a (75-90%) increase in power. With this upgrade you get significantly more torque and acceleration at the rear wheel, and your max top speed will depend on the rear sprocket size you are running (i.e. 42-64 teeth are possible)
The Stage 2 tune gives you approximately 14.5kW. This is a (175-300%) increase in power. With this upgrade you get almost twice as much torque and acceleration at the rear wheel as the stage 1 kit, and your max top speed will depend on the rear sprocket size you are running ( ie 42-64 teeth are possible)
I do not live near an SurRon Mod Shop Supplier can I still do the upgrade?
Although it may be significantly easier for us to do the installation work upgrade your Light bee. You can do the installation yourself we do provide detailed instructions.
