New Battery Upgrade
After killing the batteries previously, the bike has just been sitting around.
I finally decided to purchase a replacement battery bank. Since there are significant performance issues with lead-acid batteries (weight, power characteristics) i purchased a Lithium-Ion battery pack.
I purchased a 48V 15AH lithium pack for bikes.
The pack came with a charger too.
Since the pack doesn't offer any impact protection i knew i had to protect it somehow.
I decided to use an ex-military ammunition box. i found that the 30 cal box was the perfect size for this battery.
The added benefit of using the ammo box is that if the battery went into thermal runaway, the box should keep most of the fire inside.
Foam pad was added to the box to help with shock absorption and to prevent movement.
The battery fit quite snugly.
A hole was drilled in the lid to allow for the power cables.
completed battery enclosure
Angle steel tabs were added to allow for the new battery to slide in. elastic Strap holds the battery in place.
The result was an immediate performance improvement with low-speed torque and overall the bike is a lot nicer to ride.
