Is it good to upgrade graphene lead-acid batteries
Lead acid ebike batteries. When it comes to lead acid batteries for ebike use, you''ll generally be looking for what''s called a "sealed lead acid" or SLA battery. SLAs come sealed in a hard plastic case and can be turned in any orientation safely without leaking acid. This makes them appropriate for ebike use. - Download [PDF]
